In April I put in an Air Dog 150 and figured I would run the wiring across the radiator "bridge" to the alternator for power. Ran that setup with no issues. On the 14th of July I get 10 miles from the house pulling my fully loaded goose neck and looked down and I have no fuel pressure!! I look under the hood and the wires I routed across the radiator got sucked into the fan and shredded. I was able to get power restored to the pump to get it home. The wife and I switched all our clothes and stuff to another vehicle and left the truck and trailer at the house. I didn't want to chance getting into WV or Kentucky or there abouts and my VP take a dirt nap. So long story longer, I drove probably 4 to 5 miles with no fuel pressure. I know there is no crystal ball, but what would you guys do? Replace the VP or let 'er eat? I am sure its just a matter of time. I currently have no codes except a 1693 and haven't gotten that read yet. I just got back last night. Not to happy to say the least. One little 5 cent zip tie could have prevented the issue. I had one on each side of the radiator, just not the middle. Experience 1 me 0! Sorry for my rant.

Any advice, insight is appreciated, I do have the power on the battery now.

I ran mine without any FP for @ 10K miles (stupid I know) and have since put on 100K. I wouldn't worry about it.

Several years ago a customer brought in their fleet of five 2001 Rams for me to look over. None of them had any fuel pressure, and they may have been that way for months or years. I replaced all the lift pumps and none of the trucks ever had a VP failure that I am aware of. I know that low fuel pressure doesn't do the VP any good, but sometimes I think it gets overblown somewhat.

Put some 2 stroke oil in your fuel and run it.

2 stroke doesn't really appear to be useful. Gotta confirm forum info. Any comments on the attached?

hey were human and male. things happen. get your fuel pressure system in check with the pump. pull your code any friends have a smarty to pull the code. and run it. unless you rely on the truck daily if it went out its going to go out even at times of a new one in it. I would drive it.

So if you run a air dog you still have to run a lift pump and a VP44 someone break down what this stuff is and the best way to prevent any problems with it.

rattlerbob5.9

As a matter of fact yes.

So a little extra lubricity in the fuel on a pump that just may have been run a little dry and maybe galled internally you seem to think is a bad idea or have a problem with ??

It for sure is not going to hurt it and some people actually like the quieter running of the 24V motor with it added to the fuel.

RattlerBob,
I actually put 2-stroke in when I filled up and left so it was sucking lubed fuel when the pump wire was cut.

rattlerbob5.9

I would say that is a good thing so just continue to run it as you have been .

Of course watch for any symptoms of a failing vp - codes, dead pedal, ect.

Other than that not much you can do hopefully it goes another 50k or more for you.

did the engine die because of the fp wire problem??if not, i wouldn't worry about it. there's a lot of dodges out there that are still running w/out any pressure

A Fass or airdog etc, those fuel pumps are a better stronger more reliable unit that replaces the factory lift pump. lift pumps that are new are still weak in the fuel pressure readings. some say you dont want to dip below 5-6 psi. I dont want to dip below 10 psi Personally. most fass and airdog units keep you at 16psi to 22psi pending pump size. my fass 150 I have a steady 19-20 psi on cruise. to 16 psi on hard Open throttle. the aftermarket pumps will usually be mounted on the frame rail close to the fuel tank and this will be considered a pusher pump instead of the factory pump mounted close to the firewall being a lift pump. hope that helps

Yes thanks what is the best one to use I was looking at the Air Dog II 165 gph is this too much pump. I want enough but not too much if it is going to cause other problems. What can these stock engine blocks handle before reliability starts to become an issue?
