Fuel line for generator

Where's the leak? If the hole is where you have access then you might be able to cut it and put in a patch. If the hole is near the main fuel tank and not readily accessible maybe you can cut a hole in the flooring above to access (lots of threads on that subject - usually associated with changing fuel pump).

Lower the tank!
Change all the rubber hoses on top of it.

2005? I agree with enblethen, change all the rubber hoses.

The hole is more likely due to dry rot than a squirrel. If so, it would probably be best to replace them all anyway. My rig is considerably older, but I had to replace all of mine. I tried to drop my tank. After removing both straps the thing wouldn't budge. And in looking at it, I don't know how it would ever drop down because of the filler neck (which does not appear to be removable). I think the tank was installed before the body.

Anywho, I measured (several times) and cut a hole in the floor. As fate (or skill) would have it, I cut directly above the sender. I was able to replace all of the lines easily. I hated the carpet anyway, so that was an opportunity to replace it with Pergo.

As stated drop the tank, run the fuel down low and get you two plus pallets and a pallets jack or two floor jack. Take the vent and fuel inlet hose off. Then the straps, lower tank and change out all hoses that are rubber. Tank only has to drop a few inches to do the work. Jack it back in place and hook up the stuff.

Along with all of that if it has an electric pump and it's 12 years old it may be a good time to replace it.

some times the hard way is the best way,

Drop the tank (it's actually easier than you think) and replace the entire length. Converting the generator might cost more than paying someone to drop the tank.

Another option would be to cut a hole in the floor over the tank that will allow access to the fuel line. Just measure twist or maybe four times to get the drill point correct. Not a lot of land marks above and below the floor to measure off of.

Jaygee,

Your coach is 14 years old, the fuel lines installed last about 10 years with they new motorfuels. It is well worth your while to empty and drop the tank(s) and replace the rubber lines now with new SAE-J30 R9 for fuel injection pressures or J30 R14 for carburetor pressures. Then you should be good for about another 20 years or until they add something new to the fuel.

Well, in the spirit of rigging things up, Yes, you can always run another fuel line. Just be sure you use fuel grade rubber / metal. It's not my 1st choice (dropping the tank and replacing is), but it can be done. It's just physics.
