Hi,

So just I got home from Dallas with my 2000 dodge 3500. I am wondering if the 2000's had problems with bad lift pumps?

Are there any other issues that I should do preventative maint. on to avoid a bigger problem later?

Who makes a good repair manual for the Cummins powered trucks? (I hate the ones that include every engine that was EVER made in one manual. )

Thanks

God bless...

I picked up a Haynes manual at the parts store. I also get a lot of good step by step instructions from the tech section on this forum and forum member's web sites. Just ask and someone will probably lead you to a sight.

Someone correct me if i'm wrong, but I think it's 98.5-2002..anything with the VP44 injection pumps. Get a guage on that thing to make sure your ok :peelout

definitly a fuel pressure guage before anything. need to make sure you have at least 8psi at all times goin to your vp. once you get that taken care of you can move on from there.

Hi

cool thanks for the help. Does any one know what trans sensor helps control shifting? My trans cant make up its mind whether or not to go into OD at 40-45mph and it jumps in and out till I accelorate or slow down.

God bless...

Its is very critical that you track your fuel pressure on your VP44. If your not going to purchase and aftermarket system ecspecially. If you lift pump becomes weak. It can also make your injection pump weak. So when you/if you finally do put an after market system on. Your injection pumps will struggle. So definately get yourself a gauge. Then I would look into getting yourself an AirDog.

Do not buy a Dodge replacement lift pump. They are junk right out of the box.

Go with an aftermarket FASS or Airdog system. Put one of these on it and a fuel pressure gauge and never worry about it again. Fuel pressure should NEVER drop below 7 psi, preferably 10. Also should not exceed 20 psi or it will also damage it. These pumps are very picky. :thud:

The systems that we sell come set at 15psi straight from us. Puts you right in the middle of your max/min. pressure targets. That 15psi is for the VP 44. The rest are set to different pressures. Also you may request higher pressure settings if you would like.

My truck did the trans shifting thing once I got bigger injectors. When I had my tranny rebuilt the guy grounded one of the wire coming out of the firewall behind the air intake and it hasnt done it since. If you would like I can go look and find out which one it is.

Hi,

So I bought a Walhbro gsl392 pump and am getting ready to install it and I am thinking I will cut into the metal fuel line as close to the tank as possible and then run new line up to the fuel filter. Anything I should keep in mind?

I am huessing that the big line is the feed and the smaller line is the return line, is that right?

Thanks

God bless...
