fuel primer bulb replacement

[RibinSpain]

hi all, hope the weathers good for UK boating. I just replaced my fuel bulb, primed it by squeezing then putting finger over open end, all sealed up & nice & hard first time out..

Anyway, second time out the bulb just won´t go hard & feels like its full of air despite lots of squeezing (like 10 plus times). OB starts fine & no loss of revs but I am a bit nervous about mooring up in a remote bay with no passing boats to get assistance.

Does this sound OK? its not a Tempo bulb & it is in right direction, thought they were supposed to be hard & full of fuel, not seeming squashy & full of air.

Feedback appreciated as usual, thanks in advance.

Cheers

Check there's no air leak on the fuel line between the bulb and the tank.

....or the bulb & the engine!

cheers for replies & yes I just pulled through a few litres of fuel from primer bulb & the bulb still went soft with air after reconnection.

Having thought about it the air is upstream of the bulb (ie towards engine) as everytime I disconnect the bulb a small quty of fuel from engine end of fuel line spills out - hence the air.

Anyway, had a look & do I just pull through the fuel in engine by disconnecting mini fuel filter input line & connecting up the suction pump thingy I just bought? seems an ideal solution to get rid of any air

Thanks, advice appreciated.

Air upstream of the bulb will be compressible, so the bulb will never go hard. I'd suggest you check all the joints carefully.

Other way of looking at it, do you get any fuelling problems when the engine is pumping or puddles of fuel on the deck?
