No fuel for generator......line to gas tank?

Found out a mouse had eaten the supply line at the top of the gas tank. They ran a new line ($220) and working great again. First time in 14 years I've had a animal issue, but easily fixed. Thanks for all the replies!!

One way to test your fuel line is to push air back through it with a compressor. Make sure you open the filler cap first.
You should be able to chase the line as well - check for wire ties pulled to tight, kinks in the line, or anything else that would restrict the flow.

I've posted pictures of the sender/pump/pickup assembly from when we replaced the pump in our '00 E350 (chassis year 1999), but here it is again:



The generator pickup line is the smaller line starting at the lower right, crosses over and extends up to the left.

Full size images of the entire project are located at Photo Sharing Site - Fuel tank pump replacement.

I also replaced the pump in the generator as it would run for about 5-10 minutes, then quit. I researched this issue & found this to be the typical symptoms of a failing generator fuel pump.

Let us know what you find!

I just had the same problem last year on mine. Metal portion of fuel line was rusted and cracked by tank. Bought new length of rubber line and replaced the whole thing from top of fuel tank to generator. No more issues. I did it without dropping the tank, was pretty tight but it can be done.

Just had the same problem. Finally took it in...it was a split fuel line. They had to drop the main tank so I delivered it with 1/8 tank of fuel left which substantially reduced the cost and time. Runs fine now.

Here is something else you can try.

Unscrew the motor home main gas filler cap to relieve all negative pressure in the main fuel tank. If the generator then runs fine, you may have a weak generator fuel pump, a partial obstruction in your generator fuel line, or your chassis fuel evaporative system has developed a problem causing too much negative pressure. You would not necessarily have a crack in your generator's fuel line.

A crack would show up as a wet fuel line and the smell of gasoline. If you don't have either, maybe it's one of the other things I mentioned.

Another thought. Are you using the carb prime function? On mine, you hold the off position on the switch (does not say anything about prime) for a few seconds or until the clicking stops. Just thought I would ask.

X-2 Thats the switch at the generator.

See if you can trace it, working backward from the generator, and see if you can find a cracked, pinched, or rubbed spot. I haven't tried to work on the fuel line connections, but I was able to change the filler and vent lines on our tank without dropping it.

Thanks! Tank was full so 1/4 issue not a problem. Assuming the crack in line is the reason for no fuel, so will hope for the best.......love asking the board for advise before getting the big SCREW from the mechanic shop.

ditto above, and cracks in the line can cause it to suck air and not fuel. Attaches to the top of the tank alongside the other fuel lines and "should be" fairly easy to replace. Depends on how easy or hard it is to access the top of your fuel tank. Worst case may require drain and drop the tank to access.
