You could always buy a fass. Not to knock the new in tank pump. The fass has a 4 year warranty, is rebuildable, has awsome filtration, huge flow and separates the AIR from the fuel. Its pretty neato. Built like the CUMMINS.

I had this losing prime problem on mine aways back, left me stranded in Little Rock, AR. Had it towed to a Cummins shop nad they found a bad ground on the fuel pump. When the pump wasn't running it would back-flow through the pump and lose prime. By the way Blue, I'm with you on the high pressure pump, Injector pumps are to expensive to not get as much fuel as possible to them for coolant. Over 80,000mi on this Carter and it's still holdin 12-14 pounds. Oh heck not another Trans Am freak, is there no end to yaall.

I love this cam and would reccomend it to anyone, Its a perfect mix of agressivness and streetability. A lot of LS1 guys I've talked to that have smaller cams wish they had went with my grind. BTW mine is a Thunder Racing 224/224 563/563 on a 112 LSA. Now they have much bigger cams but most of those require a gear swap and a higher stall if you have an A4 car.
Just so you know, Thunder now has a new very special grind, its called a Cheatr cam. You get way more lift & more duration on a wider LSA without having to change your converter or gears. Here's a link for you and your pop to check out.

BTW Its a good idea to go with the whole cam package which also includes stiffer springs hardened push rods and titainium spring retainers, I did.

One of the members on here (I can't remember his name to save my life) had the exact same problem as yours and I think he finally solved it by replacing the return line. You could probably do a search and find out who it was and how he fixed it. If I were you though, I'd save your pennies and replace the whole fuel system. Run 3/8" fuel line from the tank to the injection pump and mount a holley blue on the frame and eliminate the stock fuel pump altogether.
I climbed up in the bed and looked through a hole that was cut in the bed floor (for a welding machine) anyways, I see fuel all over the top of the tank. Think this may be what your talking about?

Yup, pretty good bet that one of those crap-connect, I mean quick-connect fittings has failed .....as it has already been mentioned, you can eliminate those and just use hose clamps.

Just got back from a place here in town that works on nothing but injector pumps and deisel fuel systems and they showed me that #5 was leaking and was dripping onto the return line. After 2 attemps to tighten it the mechanic told me the tube must be damaged and needs to be replaced. Do you know where I can get a tube from? The dodge dealer dosent know what we're talking about. Thanks for being so patient with me and helping me out too.

I know when I bought my injectors from Mark here on this sight at Diesel Performance Parts he said he had them available for my truck and he had my injectors to me the day after I ordered them. If this is the case, think that will be my source. I wouldn't doubt this is a problem, when I was trying to start my truck after the IP and Injector install I had a neighbor insist he was gonna help. He's to nice to just tell him to go away, so while I was cranking the truck to bleed the air he was tightening the lines as the bubbles stopped. He's no small man and I wondered if he was cranking them down to hard, guess this answers the question.

Thanks for the link. Dad's is an MN6 so I won't be swapping converters in it anytime soon. I agree on the quality of people here vs an LS1 site. I pretty much refuse to go over to them because a lot of them are very arrogant and if your not a big power maker that has dumped all of your money into your car then you just shouldn't be driving an LS1. I love this site. People are a lot better and the information is very plentiful. It's nice not having to flip through 6 pages of personal insults and tuner bashing to get one post of decent information.

Mopar has fixed the lift pump problem,take advantage of it.

With the quick couplers prone to leaking,including the ones at the module,and the restrictive nature of the the fuel module itself,You cannot be assured that the pressure you are seeing is just fuel the guage can't tell if air is mixed in.This could be why we are have so my failures of the VP44 on lightly modifiyed trucks.So all you guys running 2 pumps on the frame wiseup Mopars fix will fix alot issues.The ultimate setup is to leave one on the frame and install Mopars improved fuelpump module in the tank.
