i keep blowing the fuel pump hose HELP I have now blown this hose for the 2nd time and had to drop the tank 3 times now
i am using 5/16 inch fuel injection hose on the line that goes from the 255 walboro to the stock housing plastic barb thing. the hose simply cannot hold the pressure. this was the hose reccomended in one of the write-ups. has anyone else had a problem like this and if so what was the solution? the hose swells up either because of the pressure or it reacts to the gas i dont know which. i think a dense plastic hose would work but i figured i would see what you guys think i should do about it. also the clamps tend to loosen up a bit(probley because of the pressure) is there any other way to make sure it doesnt come lose???? any help is greatly apreciated.

first do the trap door mod....it is SO worth it for getting to the pump. Me and my friends use hydraulic type hose...it can hold 300psi and is fine sitting in gas. My dual walbros are from my old car and that hose has been in use for a total of 5 years for me. Get you some hose at a hydraulic supply place...you have to work with it a little but probs over

They came with a hose that couldn't hold the fuel pressure.
I went to Kragen and got some high pressure 5/16 fuel hose and strapped that baby on there, Been holding up for years now...

thanks guys, just blew again today for the 5th time. ive used diff types of hose's nothing holds. this last one held for 15 WOT runs then blew all at once and didnt even stumble it flat died. had to tow the POS home. im thinking of custom making me a steel braided hose that threads on or something. im so sick of pulling this damn tank.

i found some stuff on discounthydralichose.com that is rated at like 3k PSI. its like a fiber braid with a steel layer and nitrite coat. what do you guys think? will i be able to bend it? MAYBE this could hold the mighty wally 255.
