I seem to have a fuel problem that is kicking me in the... teeth.
A short history; I bought the coach in Feb 2016. Applied GMC dropped the fuel tanks, cleaned them, replaced all fuel hoses with the good stuff, plus installed an inline canister filter and electric fuel pump by the tanks. Drove it home to Fresno, Ca. (175 mi.). The new electric pump was leaking and Jimk sent me a replacement.
I began to clean up the interior and only drove it about 30 miles with no problems until last Friday. I filled it at Costco and it took 34 gals. two blocks down the road it started sputtering and tried to die when I gave it any gas. It would idle great and start right up when it stalled. No cranking. In fact, once I figured out how to start it cold, it was pump once to set the choke then half a squirt and it would kick right over. This is a stock points distributor.

It would do about 10mph in low, any more than that and it would bog down. when I finally got it back to the shop, I changed the canister filter and the cartridge at the carb. No luck. It would run for about a mile then start acting up again. (Vapor-lock??) Maybe but The old saying if you didn't do it it wasn't done. So, I replaced the points, condenser, coil, cap and rotor. Still no luck. I needed spares anyway.

Went back and checked for blockage in the fuel lines. Clear.

I was sitting in front of the coach contemplating what to do next when I glanced under the coach and the carbon canister was dripping gas. So I blocked the leak and went home to research causes. I decided to check the separator and disassemble the canisters or maybe disconnect them entirely but I don't know that that is what is causing the bogging. It doesn't seem to be running rich.

Today I was under the rig checking my seatbelt reinforcement for Johnny Osburn and noticed the seam on the forward fuel tank is seeping. and they both look like they have been ballooned. The gas cap does not tighten so it is able to vent through there.

I'm fluxomed and need some other brains to set me on the right course. I had hoped to go to Paso for the Rally and I'm thinking I have more than one problem.

A truly happy person is one who can enjoy the scenery on a detour.
