So i was under the coach yesterday just poking around and looking at what i can do to shore up the black tank strap with the broken mounting bolt and something caught my eye......the fuel vent line "T" by the tanks....it was a brass "T" with good clamps etc....no way they had zipties or stainless clamps in the 70"s.....hmmmmmmm Rolling Eyes

So i got a quick look and it appears that someone has been there before but and here's the but....when we picked up the coach last year and i filled it to capacity for my first time i had fuel running off the top of both tanks...now the RV was parked slightly on a slope so it was running off the left corners of both tanks so i know its not the tanks seams. So to prevent that the rest of the trip home i just didnt fill it to max capacity.

So here's the question.....if they did at one point drop the tanks and they did replace the lines within the last 10 years or so...what could have been leaking? Fuel sending unit gaskets? Could the vent lines be bad again? Would their be a particular marking on the "new type" fuel lines that i could compare to whats there? Is there other fittings that both tanks have that are not used?

I suspect i'm going to have to drop the tanks either way but i just want to be somewhat prepared.......out of every job in a garage you could pick dropping fuel tanks is the one i hate the most! Sad
