Engine/Transmission (1998.5 - 2002) Check my fuel pressure please

[diesel DOG]

I installed a Westech guage from Genos and the pressures were as follows



idle was 5. 5

cruise @ 2,000 rpm 4. 0

WOT was 2. 5



I guess this is to low and lift pump is going? I am going to the dealer about replacing windshield what should I say if it is to low? Is there a minimum? Thanks for your help.

I believe 8psi is the minimum spec from Cummins. My dealer thinks as long as there is positive pressure it doesnt need to be replaced.



Do a search and You'll find lots of information.

Appears that your LP is tits up.

I kinda figured that. I remember seeing 8 lb. on the forum. I just went on a 1200 mile trip and was worried because the stuff was back order form Geno's I have 40,000 on it now. Thanks for your help. Will be at dealer in morning.

Called Herbbie Dodge today and told them the pressures. So I am taking it in Tuesday for a lift pump replacement. Glad I put the gauge in from Geno's

I'm at 16psi at idle and 12 psi wot , it's been that way since new only have 10,000 miles on LP.

Hope it didn't damage my injection pump.

It's probably okay. You caught it early. When you do power upgrades, you'll lose pressure again.

 

[willyslover]

your old one is not totally dead... . save it in the box for an emergency spare... sometimes they go to zero pressure when they go... better to have a low pressure than no pressure in a emergency situation. . out in the boonies or something like that

Good idea, dealer wanted 200 for pump but from reading here 150 or less is available.

If you are within the 5/100000, they might replace, they have changed from a psi spec to a flow spec. If dealer replaces under warranty you won't get the old one.

 

[diesel DOG]

I took it to the dealer today and he said it was fine my guage was reading wrong. I have to call Geno's in the morning. They didn't tell me the pressure . I may have someone else check it.

Filter Minder failed

I took my truck to the Dodge dealer today and he changed the filter. I looked at it and it looked dirty but the minder just started to move. I hate to admit it but I had 39k on it and 3 filters sitting in my garage. The truck definately feels a lot faster. I have heavy equipment and they work good but are Donaldson filter systems. I dumped a ton of tools out of it last week and that helped too. Now it is really flying. It did feel like a slug lately but didn't know if it was me. I think my mileage is increased a good bit too. What a jerk I was. So much for the minder new filters at 15,000 now. I know there was a TSB if you know where I'd like to read it.
