Where is all of my fuel going?

Yeah, I'm down to about 1/4 tank right now. Should be an easy pull. I won't get around to it until next week, tho.

Motorcycle jacks work pretty good with a fuel tank. Noticed, the fuller, the better. Less sloshing to cause the tank to slide off, if you don't have a strap handy.

+1 on the condensation thing, mine sat around for a couple years with a half tank in it and I decided the middle of winter was the perfect time to fire it up and start driving it again. Every morning for 2 weeks I was on the side of the road bleeding my injector lines from the water freezing up in the fuel system on my way to work.

Well I did some more poking around yesterday. The lift pump is now very suspect. How can I tell it's done?

This weekend I got after it. Pulled out the LPLP and installed my leaky stock diaphragm pump. The stocker pushed 5psi right off the bat. After further inspection, I found about 1/4" of crap stuck to the inlet screen on the LPLP. It looked like paper towel or rag material. I have a feeling I know where it came from. I washed all that crap out and installed a clear inline Fram filter. I will be keeping an eye on this. My pressure is now 17 psi (after I installed the LPLP again) which varies a little. I may pull the fuel tank later, but right now I'm too buzy/lazy.

Plus, I have a fuel filter to catch anything else. . .

don't forget about the screen in the tank, it could be partially plugged also..

Another thing to look for is any cracks or leaks pre lift pump. They arent as pressurized, so they may not give themselves away as easy. We bad a pre lift crack give us a hard time one day. I ended up lightly pressurizing the tank until I saw bubbles and diesel. You just gotta make sure pressurize it lightly, and have a friend to watch and look.
