lift pump is history

[Cobra]

Hey Guts,

Just one month ago I put gauges on my truck. I was very happy to see 14 to 15 psi fuel pressure at idle and never less that 10 psi at WOT.



The other day my fuel pressure dropped to 3 psi at idle and even lower going up hill at 55 mph.



Convinced that it was the gauge I took it back to ADT and Andy used a mechanical gauge. 3 psi at idle.



Tthis morning I went to the dealer, they first said they thought it was the gauge, but upon checking with their gauge, found it to be 3 psi at idle. They ordered a new pump. Hope the truck runs until the new pump comes in. About a week he said.



Oh yeah. 10,000 miles on the truck and yes warranty.

I just hope that they get the newest model pump.

Cobra, I would park it until the replacement pump is installed.

I'm with TopFuel, do not drive your truck until the lift pump has been replaced.

Thanks for the advice guys. I put the beast in the garage and there it will stay until I take it back to the dealer.



Andy at Advanced Diesel Technology, told me they have a new generation pump that is better than all the rest. I hope I get that one installed.



Has anyone heard of the new pump or have any info.

My fuel pressure low too!!

As soon as I started it tonight, FP was 0, after about a minute it slowly started to rise. It took about 3 minutes to get to 15 psi and then it would drop like a rock as soon as I got on it. I shut it off and tried it again and some thing. Is my lift pump headin' south for the winter? With only 2600 miles, I hope not!

Does Advanced Diesel Technology have a website?

Cobra,



Check the fuel filter and overflow valve before changing the pump... It's probably the pump, but its good to check the other stuff out too. Use regulated air pressure to check the overflow valve. It should open up at 11-12 psi. BOMB on.

Over flow vavle??

Where is the over flow vavle? I hope I can fix this, I don't want to mess with the stealer.

Turboman,

I'm not sure you have a lift pump problem by the sounds of it. Even Backs advice is good, and you may have a bad fp gauge.



Even Beck,

Thanks for your advice, that was already done. Thanks again

Our 2002 runs 16+ PSIG fuel pressure at idle. At WOT towing, it will drop to 11-12 PSIG. 4700 miles on truck at this writing. Will this new design live... time will tell, I guess.
