Generator Supply Fuel Line Problem

I'm going to search, and have already, but decided to post my question. What is the procedure to replace the fuel line from the gas tank to the generator on our 2000 National Tropi-Cal 36' gas rig.

Apparently there is an air leak in the fuel line going to the generator and I'm hoping there's an easy solution, or one that's more reasonable than having to drop the fuel tank or does someone have a better solution. Does anyone have links to the specs or diagram to help?

There doesn't appear to be any gas leaking, yet I smell gas around that generator all of the time.

Thanks for your help!!

This may or may not be your problem.

If your generator is an Onan 5500 and never modified, it will have 2 fuel filters at the generator. I had the same problem as you and found the upper filter was leaking. The "fix" is an updated setup that replaces the top filter with a new fitting that eliminates the filter. You have to go remove a few things to get to the top filter but you can do it yourself.

The fuel filter part # is 149-2341-01
The adapter part # is A026E529

I ordered from a Cummins dealer.

Not sure that's the problem because when I put a gallon jug of fuel and hook a line onto it directly to the generator, it cranks up and runs until I run out of fuel. But, thanks for that info, I will most likely locate the two filters and do what you suggested. At this point I believe there is a possible air leak (apparently even a pin-hole sized leak can cause an air leak, preventing fuel from reaching the generator.

Thanks, again, UFO Pilot.

Maybe a silly question, but you are at over 1/4 tank of fuel? Just asking.
Did the fuel line replacement on my buddies rig, and yes, we had to drop the tank.

I had this on my gold marquis generator on my dolphin 6320. I found a garage, not an rv shop, who replaced the fuel from tank to generator, they did have to drop the fuel tank, but just enough to connect the new line to the fuel tank connection which is on top of the fuel tank. Took them a couple hours and charged around $400. The line was a solid except at the ends. They did not remove the old line. Be sure they don't leave too much hose at the generator end. Thay did on mine and was plagued with vapor locks at high amnient temps. Removed a portion of the excess line and havent had any problems since. The frustrating part was i kept asking if it could be vapor lock and all said no way need new fuel pump etc. Finally i took matters in my oen hand and removed some of thr excess hose and it has worked flawlessly. Good luck

Several times we had this problem on LP generators. A wasp had plugged the vent in the LP gas regulator. Carefully check the vent to make sure it is clear.

What lead you to a valve adjustment ?

First thing to check, when popping out the intake is a stuck or burnt intake valve. A compression test would help ID that.

Was it popping before the adjustment ?

If not, it may have been done wrong.

Did not run when I bought it,trying to start it,it pops,after I did get it started,it still popped. On this forum there were suggestions that fuel mixture maybe off,carb may need cleaning,weak spark,and a few others.
After it runs a little it smooths out and purrs,so it's not the valves (luckly) but it's still hard to start and sometimes doesn't.

I had the same problem on my Ford Chassis Dolphin. A critter chewed through the generator fuel line above the tank. Generator would run and die, run and die. Took it to a local RV service, they dropped the tank saw it was critter damage , submitted to insurance, adjuster came out and authorized insurance to pay for repair. Lucked out of that one, till insurance dropped me. They stopped all RV insurance underwriting, not just me.
