Sometimes hours apart, sometimes not long at all. Sometimes it would read full tank when I filled it, sometimes it would read less than full.

There are those fill valves on the bottom of the canister.. on level ground it would only take maybe 1", if even, of fuel depth to get to the fuel pumps. So if the tank was quite low, it would be no surprise to have fuel pickup issues on a steep hill since the fuel pump mounting flange is about in the middle of the tank (front to rear) and so is the venturi pickup on the driver side. But since it sounds like it didnt want to run even on level ground until you added fuel, I have to assume that either the tank was legit empty (level sensor reading optimistic), the check valves are blocked (unlikely with such a new installation), or perhaps the fuel pumps are too high (i have seen people slide them all the way up in the pump holder rather than setting them so the pickups are as low as possible)

It is one of the fuel sendors. One of them is bad. I had a full tank. Went for a quick drive. 1/2 tank. Put 6 gallons of fuel in it and it still reads 1/2 tank. LOL, There done.

That is a large amount to lose. So the sensors are wired in series, out one into the other and out again to the gauge. If either of them had a broken wire or crimp that came out, the gauge would entirely die.

Ive attached a page from the service manual for determining which sensor is bad. If you fill the tank again, without having to open the tank at all, you can just unplug the tophat on both sides of the tank and test resistance across the sensor terminals. Both should read about 3.0ohm full... whichever one is way out, is your culprit. I will bet its the passenger side, since its been handled more.

Also, dont open the tank until you think its more than halfway empty, or it will make a big mess.

Hey Phunk,
I need to know what to order to replace both of my fuel pumps since I am going back in there to replace the fuel level sensor. I need to know what size hose I need to get to run from the pumps to the tophat. The size for Warlboro 450 and 525's. They are 3 yrs old. Might as well. I don't want to go back in there again for a while.
