In line fuel filter may hold the answer!! Fuel contamination

Post by **philb** » Mon Oct 19, 2009 9:19 am

Hi all

Have been telling you all about running issues with Patsy. Changing points, coil, etc... rebuilding carburettor, timing, mix etc... Not getting anywhere.

Well last Thursday we fitted an inline fuel filter and were shocked to find a mix of silt, water and fuel running through it!!

No idea how on earth the tank has become so contaminated. We think it's relatively new (5-6 years old) and was fitted by previous owners at a coachworks.

Any ideas how water could have got into tank?

We are going to remove tank and clean it / check it tonight.

Any tips? Other than the serious Health and safety precautions.

Condensation! Empty, or near-empty tank contains air which has moisture. In the cool of the night it condenses and sinks to the bottom. Regular use washes it through in tiny amounts which the SU is well able to deal with. Dirt of course comes from RUST in the tank. Some coat the inside of the tank with POR and other potions - others have reported this clogging up the fuel line - so beware! A little Meths added to the tank mixes with the water and will carry it through with the fuel - obviously this can only work with a small amount of water!

Don't think tank is that old so hoping it isn't rusting away!

Any tips on removing & cleaning. Do the tanks have bevels?
