LP Pressure
Hey guys I just bought an other 2001 dodge ram 2500 4x4 that I thought it was a good deal I bought it for $3000 with the transmission out it has a NV5600 the guy tore that thing out I had it rebuild for $1500 the truck has 226000 miles , it cleaned out pretty nice . I am not planning in putting a lot of money at the time other than what it needs but I also want to prevent spending more like the Vp44 going out so I have installed a fuel pressure gauge and this is my concern, at idle I am getting 11 psi and at WOT between 7 and 8 psi but when I am taking off and I step on it some times it gets pretty close to 5 psi sometimes almost under it when I step on it hard so I've been taking it easy and being very careful not to get under 5 psi. What do you guys think?

Well, with those numbers there are 2 issues.
1. the lift pump is likely gone or going. Replace it with something with filters on it (read Air Dog or FASS or whatever else)
2. the VP44 may be prematurely worn as a result of the low WOT pressure but by not goosing it and addressing the LP you may be ok - it is tough to say though.
Throw a code reader on it and see if there are any issues beyond what you now see.
