fuel line problem?

[dewey123]

I had some carburator problems 3 weeks ago and limped back in on the trolling motor in the lower niagara. 2 weeks ago i put an inline fuel filter and also a water separator. I noticed it doesnt prime like it used to. When id squeeze the primer bulb it would be firm, now it doesnt firm up and seems like it doesnt prime the engine. My question is the loss of fuel pressure normal or and i going to have to buy a new fuel line and scrap the filters? I cheecked for any leaks and it didnt seem that anything was leaking.

First check the fuel line primer bulb by seeing if it draws suction on the fuel tank. The gasket on the water separator may not be tight and allows air to be sucked in instead of fuel. Threaded fittings may also leak.

it does draw suction on my smaller tank 6 gal. but not on my bigger 12 gal. tank.

but the suction from the smaller tank isnt what it used to be

The primer bulb needs to be bigger. The rise is 2 times that of the small tank and didn't have enough suction to draw it up the tube. I figured id post the fix so if anyone else has this problem it might help them

did you fill the water separator up with gas before putting it on the boat?
