Fuel Line Question

[ski_bum]

Hi Guys,
I'm a total rookie, I have a 71 Merc 7.5 hp. I bought a used plastic fuel tank with the newer style Merc connection and a new fuel line with the old Merc motor connection on it. I cannot get any pressure in the bulb. Could it be a problem with the tank? No fuel is leaking from anywhere when I am pumping the bulb... Help please!! Cheers.

You might have a bad bulb if its not pumping at all, or the pick-up line is off in the tank.

The bulb has small arrows on it showing the direction the fuel should be going. Are they pointing towards the motor?

Point the arrow towards the motor line and point the arrow up when squezing (priming) the motor. Make sure the vent on the tank is open.

I found the culpret, I bought the fuel line new from Canadian Tire, it had these clamps on it that were not doing their job, I installed new hose clamps and it pumped up firm right away! Thanks for the help!
