Sometime back, a poster described his experience when changing the fuel
pump on his '88 Chrysler mini-van.

He mentioned that the fuel pump and inlet screen were coated with a
thick gooey substance, which I am guessing was varnish.

Is there anyway to prevent this type build-up from occuring? I know
that fuel tank additives are not recommended, so what other options are
available? Are some gasolines better than others in this regard?

Thanks,

Kirk Matheson

If you use your car regularly, I can't see how you would get the goop in your
tank.

Yeah, don't be one of the people who used Shell gasoline in 2003.

Well, tourniquets are not recommended on healthy limbs either, but if
you're gonna die without one, maybe you should consider using one.
Seriously, why make a hard and fast rule that you will never use an
additive? Nothing wrong with using them with common sense and a real need.

I would think that an alcohol-based additive like Dri-Gas™ would help
dissolve and disperse that kind of thing in a harmless maner. Might be
some other types that will work better if it will put your mind at ease
to use them without doing any harm.

Continuing with the tourniquet analogy, of course it would be better not
to rip your arm off in the first place - IOW - avoid the problem in the
first place. But if goo in the gas tank concerns you for whatever
reason, by all means use an appropriate additive.
