Have a 1996 Johnson 150 FastStrike. Boat would not start/turn over and discovered a cut in the old fuel line. Per recommendation from this forum I replaced it with a 3/8"ID fuel line I purchased from Bass Pro. To replace I pulled the old line off the thru hull metal fitting (which goes to the gas tank) and off of the engine. Cut the new line to a similar length and put it one. Used metal, ratchet style clamps (worm screw I think...tighten with a screwdriver) to tighten at each end. Pumped fuel bulb (took alot of pumping). Eventually boat turned over. Took it out today. 2nd time starting engine it would not start/turn over. Found fuel bulb would not really stay firm. Sounds like air could be in the bulb. Therefore I believe either I installed the fuel line improperly (maybe need to fill line with fuel before attaching to engine?) although I did ensure flow was towards engine lol. Other option is it's a crappy fuel line....doesn't feel real 'sturdy'. Appreciate any ideas!

Thanks,
