There seems to be alot of knowledge here, so ive got a question for u guys. Im at almost 110k miles on my 01 ram. From reading some of these posts it seems as though i should be thinking about replacing mine. My questions are 1-is the pump inside the tank 2-what kind of pump can i use, can i use a holley or is there a special pump, i want to do this right but not spend a ton of money 3- what fittings will be required 4-how many psi should be going to the injection pump. I think thats all for now. Any help is apprecieated. Ryan

 

Please see this link on the fuel system components and location. Once there you can look around and find out other things you may want to see. The fuel pump is located on the left side of the engine. My first pump went 95K. I caught it just in time. There is also a test procedure at this site. If you can't find it let me know.

Ryan, there's a lot to learn! A couple of things you might do is first of all, fill out your signature line so we know at a glance what your rig is and how it is configured. Secondly, use the search feature on this forum and you'll get lots and lots of answers, and most of them pretty good. And one more thing: if you don't at least have a fuel pressure gauge, you're flyin' blind; you've gotta have one! There are good sites to get hardware at, such as Diesel Manor, Geno's Garage, and Transitowne Dodge in NY state if you want MOPAR at a discount. Hope this helps.

 

Like yukon said, get a fuel pressure guage, either in or out of the cab. in-cab is preferable, but under hood fine for starters. If you have 12psi or above at idle your probably alright for now. superduty has a couple of good threads in the gen diesel forum, it is alot of reading but is very informative. He is using a hi pressure pump regulated down to feed his cummins/ford conversion.

 

Not really....you need the incab guage because you need to see how well the lift pump is working at Wide Open Throttle (WOT)....the lift pump pressure at idle is essentially meaningless.

 

You have a good point,,,,,,,,,,,,, However,,,,,,,,, under the hood is better than nothing and if the pressure is below 10 psi at an idle,,,,,,,, you can be assured that you are in need of a lift pump. I started out with one under the hood till I got the one installed in the cab. I run both now,,, one before the filter and one after the filter. One thing is for sure,,,,,,, FLYIN' BLIND is no good. I saw a guy in TN that was complaining of poor performance when he towed a barrowed 5er to a meet,,,,,, when we hooked up a temporary test gauge,,,,,,, it was showing a vacuum! The VP-44 was doing all the work and he never knew it till then.

 

i have a 2002 3500 dodge cummins. 5in exhaust and hypertech chip. when i go under a load or up to 3 rpms it cuts out. have replaced the apps sensor and i am going to get another under warranty. new air and fuel filters. 161,000 miles. any suggestions?

 

At 3000 rpm's its possible the computer is defueling the engine.

 

At a 161,000 miles where did you find an extended warranty,I want one!

 

Thanks,guys I guess i better be getting a pressure guage, wheres the best place to get one. Oh yea i think i fixed my signature

 

You now are an OFFICAL DTR MEMBER!

True enough Dennis....but a temporary or underhood guage wont show much if your lift pump suddenly takes a crap. Luckily, most dont , they die gradually.

But, for $19 why not have an incab FP guage?:

Ok guys heres what i have. I used a standard fuel pressure test guage today to see where i stand. Its an actron test guage. I hooked it to the fuel pressure test port.......................and absolutely nothing, at all, needle doesnt even move. is it possible im using the wrong guage. And also anyone have any links for in cab guages?? Thanks Ryan

 

Yes, it's possible. Your fitting needs to be similiar to a air chuck, it should have a thing to depress the schrader fitting (or you'll get nothing)

Look in the end of the hose you connected.

Heres a good spot for gauges:

You don't need anything fancy, I think a f/p gauge with related tubing is about $35.00
Search threads here for needle valve installation.

 

Short term you can gut the schrader to get a FP reading. The tool you use on a bicycle or car tire will work.
