well i just ran into a problem, the truck has 2 fuel tanks, only one i use because i am afraid to run gas through the rear one because the previous owner said he never did in the 5+ years he owned it. so theres probably rust in there, but i knocked on it and nothing is in there and when i flip the electrical switch to it from inside the cab is goes to empty. the two spots i was debating on the exhaust exiting points right to it and the other is directly even,maybe 2" behind the front tank which i use, even with a turn down tip i would think the heat at idle or at a stop would build pressure in either one
