Hey guys, thought I would let everyone know that I FINALLY fixed the problem. It was the injectors. Bought some new Bosch RV275s from diesel auto power threw em in and the problem went away. Just my .02 DO NOT buy injectors from Pensacola Fuel Injection. The ones I took out looked horrible and only had 70K on them. Ryan

Thanks Rogan! I'm more than happy to help in anyway I can! I just know that if I were in that situation, someone would surely help me out. I may not get on here or post a lot but my number is listed and if anyone is in my area and needs some help do not hesitate to call! Thank you all for the kind words!Ryan

Well, now the truck doesn't haul much of anything, but I used to haul hay, which was loads in the 15k range, not counting truck and trailer and it would draw down to about 8. I had a typo, the fuel pressure stays around 11-12 and 14-16 at idle.

Well this may make sense because I noticed the rough idle started after I delivered a load of hay. As far as lift pumps go, what would be a good replacement option? Raptor? Thanks again,Ryan

9-10 psi when driving, and as far as gaining oil, I don't know what you're talking about. I have normal levels of oil when I check it. I have not tightened the t on the back of the motor, and it was replaced all OEM. I don't believe it is the injection pump. It was replaced march of last year, and hasn't lost fuel pressure at any time. Everyone else has said its something to do with the rubber lines. I'll check those and let you all know.Thanks,Ryan

So how would you go about seeing if this is the problem? Just replace them?Thanks in advance,Ryan

Well, I got my fuel pressure gauge squared away, and I'm running 9-10 psi WOT. However, the truck still has a rough idle after running for a few miles. If it's parked with uphill, the system has to be reprimed. If its parked level or downhill, it will start everytime. The rough idle will go away if the A/C kicks on or if you shut it off and turn it back on. It shouldn't be the VP44 (it and the lift pump were replaced March '10.) I've read that its most likely an air leak in the return fuel line, but I can't figure out where it's coming from. Please help, this is driving me NUTS!!! :banghead:

I did not install a needle valve, a mistake that I realized a couple of months ago. Can I pick one up at lowes or home depot? and how do I set it properly? As for a pop test I've never heard of that? I haven't hooked it up to a OBDII scan tool. There isn't a check engine light on, but I know that there are "silent codes." Can advance do this for me? or another parts store? Thanks in advance,Ryan

Hey guys,I'm new on here but I have a question that I haven't been able to find a good answer for. When I first crank my truck it is hard to start whether hot or cold. When it does crank it idles fine. After driving maybe 5-10 miles and stopping at a red light the idle becomes real choppy. If I shut it off, it will fire up normally and idle just fine, but 5-10 miles down the road the same thing happens again. I have a fuel pressure gauge and for some reason when I was pulling a load it jumped around and then stuck maxed out. Every now and then it will jump around but I never get a normal reading like I did when I first put it on. I do not have a snubber or needle valve on it, so that is probably the problem as far as the gauge goes. Any suggestions? BTW, the injection and lift pump was replaced in march of 2010.Thanks for your time,Ryan
