89 fuel line issue

[tahititreat]

I have air locks in my fuel lines. I take the line off at the carb, pump the fuel til it's a steady flow then put er back on. Within 10 min. i am no longer moving and have to do the procedure all over again. I replaced the lines, the carb and removed the filter to run a direct line from the tank to the pump to eliminate possible air leaks. Any ideas? Fuel pump? It pumps but not real hard. Thanks

They do not pump hard check the vaccum line to the crackcase for leaks....

I would check the pick-up tube in the tank. If it has even a small crack in it, it will give you an air lock. Like sucking through a broken straw. Could also be a small crack in the diaphram in the pump. Not likely but not impossible either.

Check your lines... you have a leak. That walbro style pump will never make more than 7 psi pressure... when it's new maybe. 4 psi used. Vacuum style pumps work better in volume , not pressure. You have a line leaking that's sucking air somewhere. I have seen plastic fuel filters seams leak.
