[Spring44]

I just revived my '84 944 last fall after seven years of storage and the fuel pump was locked up by gasoline varnish, rust and and tar. I bought a new pump on e-bay for about $30. It is a little louder than the old one but has worked fine.

Before you put a new pump on, drain the tank and unscrew the fuel strainer from the fuel tank sump and see what kind of trash is in the sump and screen. Then, go from there depending on what you find. I found my sump full of rust, gas varnish and the screen was plugged with a very viscous black tar. Use spray carb cleaner to clean the strainer screen and don't scrub on it, as it is very delicate and costs nearly $100 to replace.

I wasted a lot of time, money and effort trying to clean the tank by flushing it with gas and acetone, but only succeeded in plugging 3 fuel filters and my refurbished injectors. I finally bit the bullet and dropped the transmission and fuel tank and had the tank professionally blasted and coated inside and out. It cost north of $400 for the tank but it is well done and has a lifetime warranty against rust and leaks. (New tanks are still available but cost $1800.) Have had zero problems with mine since then.

Good Luck
