Reo multi fuel lift pump problem

[rustexpert]

Hi,

i am working on a friends Reo.

It has been standing for several years. The fuel lift pump in the tank is completly gummed up with a soft varnishy type deposit that has come out of the fuel. Has anybody else had this problem which I assume wouldn't affect a vehicle in regular use.

Is there a solvent which will dissolve this stuff; or a readily available alternative pump.

Thanks Rustexpert

Try soaking it in fresh diesel for a day or 2. Problem with Reos is you dont know whats in the tank.
