Yea, I bought it from a teenager who had put the new tanks on new hoses so i know he was in there changing things around, It's like the pressure builds up immeadiatly , like there's no bleedoff at all. everything is in the tanks( pump, valve etc.)don't have that same problem w/midship tank although it is slow to put fuel in. It's the fuel that should have the high pressure not the tank correct?of course it will have some. Did all this change to fuel injection etc. really improve the milage over a carb? I guess my question is there anythingother than the return line and the canister to relieve pressure. i should be looking for?

I JUST LOOKED THRU THE ON-LINE REPAIR MANUAL AVAILABLE TO ME, I CANNOT FIND THE TANK SET-UP IN IT....OR I WOULD SLING YOU A DIAGRAM, SO YOU CAN CORRECT IT.

IT REALLY DOES SOUND LIKE THE PUMP IS PRESSURING THE TANK UP, MAYBE FROM ONE TO THE OTHER....I DON'T KNOW THE SET-UP

I WOULD RECOMMEND THAT YOU SPEND A LITTLE $$$ FOR ONE OF THESE
