have you checked the line and junctions for leaks/weeps? can't be just the check valve can it? from the way you describe it, sounds like there is a weep somewhere in the system that is contributing to the slow drop in pressure.
All the joints in and around the valve and the regulator are dry. There are only a couple others in the whole system. I will double check all these before I get the truck back on the ground but I don't expect to find any leaks. But as I mentioned, the pump has no issue bringing the pressure back up instantly compared to when the fuel was drained out of the system and it had to refill the line.

If you need to return that check valve' date=' feel free to do so![/quote']
Im gonna leave it just as a space filler. Otherwise I have to rework everything. Thanks though. And thanks for your emails.

Update:
After going back and forth with James and not quite knowing what direction to take I decided to try replacing the "new" fuel pressure regulator. It wasn't an ebay one but it wasn't an Aeromotive either. So I ran to jegs and got an Aeromotive unit to try out.
Its 90% fixed!
It takes several minutes to bleed off to zero. It does bleed to 40 pretty quickly but then very slowly after that. The pump seems to be able to bounce back a lot quicker as well as soon as I put power to it. Its still weird by the check valve wouldn't hold the pressure in the line even with a junky regulator.
I have the worst luck with junky parts right out of the box. Even when I try to buy OEM parts a lot of times I get dead ones.
Either way Im satisfied with it for now.

again, sorry for the hijack
Well when you put it like that it seems to make sense to spend the extra money - it's a real value to have easy to find sensors, plus actual port fuel injection, an dedicated and calibrated ignition system, and a cpu that can be easily accessed by an android device. I see edlebrock makes a setup for pontiacs so it might just make sense to port match the manifold that comes with it since it's not a big job.
And its not really any extra money compared to the Holley when you add in the cost of the timing control. Its basically the same cost with the added "benefit" of port injection. Even though this typically doesn't make more power..

Coincidentally to this question, I've been watching "Snidertron3000" and Hoonigan...and both of them were using Holley Snipers in their traditional Chevy V8-powered truck projects.
How do you have a coolant temp sensor and a fan switch wired up to the FI box? I thought I remembered something affecting the system operation...not sure if that affects the injectors remaining opened to bleed off fuel pressure maybe?
The coolant temp sensor is hardwired to the holley unit. And Im not using their fan control. I have a separate Dakota Digital unit for that. Neither of these to my knowledge could affect my scenario.
-
as a side note, how do you like the holley sniper and the Fi-Tech stuff in general? been thinking about this system for the GTO down the road, the Fi-tech price makes it hard to pass up, but people say the sniper is the better computer/throttle body.
I haven't had any issues with the actual hardware or software.
Its been a lot more work than I initially intended, no fault of Holleys though. Between switching fuel systems and ignition systems its been time consuming.
I recently added their hyperspark distributor, coil and module to add timing control to the system. This required a complete rework of the wiring in the engine bay for the most part.
I havent' gotten a chance to drive it yet due to the weather.
The software seems pretty simple to operate. Ideally Id like to take it to Brian Turner and have to smooth out the tune once I some hours on it. Ill do some on my own just because I can but not having it on a dyno Im just guessing.
I like the look of that edelbrock system. Now that its cheaper and knowing what I know I would have seriously considered that instead of my setup.

You can use a https://www.jegs.com/i/JEGS/555/15276/10002/-1 fuel sample valve to ensure you aren't bleeding back at various points in the fuel system. The check valve you are using bleeds off at less than 1DPM (Drip per minute).
What does the pressure gauge say at the regulator? What sniper part number is it?
Shoot me an email and I can help you. james.flanary@jegs.com

Soo, Ill try to make this as short as possible.
I built a new fuel system for my C10 to get rid of the FiTech fuel command center and go with a more normal in-tank mounted pump with a returnless feed to my Holley Sniper.
I set it up like any other fuel system I've seen.
Holley Hydramat mounted to a walbro pump in the tank.
I have 2 lines coming out of the tank. 1 supply to the pressure regulator (filter before) and 1 return from the regulator back to the tank. I then have the supply running up to the Sniper with a gauge at the Sniper. As shown below.
The sniper primes the pump when I key on. But as soon as the pump turns off the fuel pressure bleeds from 58psi to 0psi in about 10 seconds. So I figured this particular Walbro that I had/found/barrowed didn't have a check valve. So I ordered one from Jegs and installed it after the regulator. It does the exact same thing. I took the valve apart and everything seems to function as it should.
Here's the valve.
If I key on but don't start it right away the truck definitely long cranks when the pressure dies off before it can build back up again.
I don't know where to go at this point? Im can't think of any good ways to diagnose where or how the fuel is returning back to the tank. Ideas?

I don't have my 4 wheeler anymore, but loved to ride.
I think what you'll find is most ATV guys don't like the side by sides, they take up more of the trail and are slower then a lot of quads. Same reason the dirtbike guys don't care for quads. In Wayne or Perry I can't believe they allow side by sides because most of the trails aren't big enough, and there's certainly no room for them to pass each other.
They are limited to 60" or something right? So small'ish side by sides. Pretty certain they don't allow full sized ones.

Never seen one before... The front is not bad but that rear...

1) Buy a $150 truck.
2) Go off of the road.
3) ???
4) Profit.
I was comparing the $15k Roxor to a $15k side by side.
-
Curious what the side-by-side UTV crowd thinks of the Mahindra Roxor?
It doesn't look all anime, razor-bladed styling with Chinese alloy wheels and a motorcycle engine...but looks like it would be a fun off-roader.
That's neat'ish. Ive never seen that before.
Im curious as well what someone with more experience thinks. Ive never offroaded in a jeep/truck. I feel like for the same money a side by side would be the better choice. Better suspension for one. That would be enough for me I'd think

I've been to Brimstone with my brother. I'd highly recommend it. Its massive. Ive heard good things about Rush Offroad which is a bit closer as well.
I'd love to own a SXS but can't justify it as I have no place to ride one even in the state.
We've rented them all over the place though. Anytime we go on vacation we try and rent them. We've ridden at Silver Lake & Manistee in Michigan. We rode in the White Mountains in New Hampshire. The east side of Lake Tahoe in Nevada. Last fall we rode for about 8 hrs in Sedona, AZ. Love it, we always rent RZR 900 or 1000's. Anything less is a waste.

Its because I bought winter tires this year that our winter has been warm....
-
We went to the Hartford fair and saw demo derby a couple years ago. It was on par with the ones I saw as a kid up in Knox county when it was a big thing.
-
It was incredible and saddening at the same time. To be that gentleman and have all those cars means he was buying a couple a year. And to have fixed /restored many of them seems unfathomable. Even just to store them/maintain them in all those barns/garages seems like an inpossible task even if it was financially feasible. Hoarders sure are an odd bunch.

Funny because I have the opposite view. Wasn't a fan of Nelson from a course design perspective. Also, our event was the same price or more than a single day at mid Ohio, where are you finding cheap Nelson track time?
Rymer and I are doing gingerman in May, and I'd like to do Pitt also but we will see. Let me know if you plan a Pitt event.
A friend of mine in Cleveland met some guys that run their once a month during the week for cheap. So Ill be joining them. Ill let you know if they are looking for some more folks.
Ill probably do Pitt for Carfest in September with Auto Interest. Ill let you know if I do something different.
Derek, sorry to hear about your experiences at Mid Ohio. I'm a big advocate that if someone can be fast at Mid Ohio they can be fast just about anywhere they go, really rewards a technically sound driver and doesn't require a big HP car to be quick.If you like Nelson then you should go check out Putnam, similar flowing layout, generally cheap events, nice facilities and maybe 40 minutes further of a drive than Nelson.
...but you should all go to Pitt first!
Andy, I believe you completely. I do feel sorta overwhelmed at MidOhio. I feel like if I had the option for loads of private track time there I would get to the point of enjoying it. Much of my dislike comes from never having traffic free laps. I always end up with 25 cars on track and so you never get a good feel/flow for what Im doing.
I do want to get to Putnam. Ive heard good things. And yes, Pitt is my favorite, by far.
-
Yeah, Derek, why do you do Nelson over mid Ohio?
Do mid Ohio with us...
I wish I had a good answer. I just DON'T like Mid Ohio.
I just don't have fun driving the track. I don't have a good reason why.
And...everytime I've gone in the past 3-4 years the weather is crap.
Im not saying I won't go with you guys but I'd much rather spend less money and have more fun @ Nelson. Ill take the the extra money and to go to Pitt once a year as well.

I plumbed in a new softener and holding tank in my basement last year. In that corner of the house is where my outside faucet is plumbed for the porch and driveway. I decided to add in a hot faucet for winter car washing. I extended the hot plumbing to that corner and just put in a new faucet next to the cold one. Its awesome! I want to find a Y that I can introduce cold water so that its not 120* but Ive had trouble finding one that doesn't restrict the flow badly. I love it though.

shucks, just replaced mine 2 weeks ago.

There are laws but if that specific liquor can be sold in Ohio then you can buy it from out of state and shipped into the state
Good to know. Thanks

Isn't there a state law against having hard liquor shipped into Ohio from another state?

For sure. I didn't do enough research on changing out my existing low pressure parts for a high pressure setup. I thought I was gonna have to buy an expensive FI tank and run new lines, etc.
In reality it would have been cheaper to just do this from the start. Hind sight is always pretty clear.
I was able to get decent money back on eBay for my fuel command center. I think I had it to the point where it would work well but I just didn't trust it after having it strand me right off the start.
btw, I follow your guys' stuff on YT.
