P1800ES Fuel Starvation

Post by kenmgregory » Fri Jan 22, 2016 5:16 am

My '72 ES runs great for about an hour, then the fuel pump starts whining and it loses power. Clogged tank outlet? It sat 6 years without being run.

Thanks,

Ken

I would start by dropping the tank and checking it for sludge and clean/replace the tank strainer.

If it's like my 73 ES, you can't remove the fuel pickup without cutting the tank open. Also, it's hard to clean the tank out due to the baffles inside. Try loosening the gas cap and blowing air backwards into the tank through the pickup tube. That will often break any crud lose that might be restricting the screen.
