This is a fully rebuilt 1986 merc 115 L6. 40 gallons ran through,break in has been done.
Im thinking i have a fuel delivery issue and i went to test my fuel pump (old style/rebuilt) by pulling the line off the top of the pump that feeds the carbs. I hit the kill switch and turned the key.. it will pulse gas out of it twice then nothing. I prime the bulb again, hit the key and it pumps gas 2 pulses and quits..
Is this correct procedure for testing?
Shouldn't it just keep pumping/pulsing gas?
All fuel lines have been changed out from tank to carbs. Only thing i havent changed was the primer bulb.. wonder if thats going bad.. it pumps gas and primes.. wonder if the vavles are allowing gas to flow back into tank.. hmm..
