Why is carb body gasket made out of fiber?

perryjosh64 · Dec 11, 2020

Folks this question is on why carb body gasket to the fuel filter valve stem (banjo bolt) is made out of "fiber"? Working on a 1964 Ford 2000 4 cyl gas tractor. I ask because when I ask local parts store most say they don't have "fiber" gaskets and I'm wondering what's the difference and can I use any gasket material as long as its gasoline compatible

The torque that can be applied to the thin sealing area of "banjo bolts" will distorte almost any other material with the exception's of
copper, aluminum, and some hi-density fabric such as you have. Get the copper washer-gaskets and that will be the end of it.

that fibre washer is common on all fuel line fittings back then. next best is find copper if cant get the actual fibre one. gasket paper will
not work.

I would try to find fiber washers.

It's easy enough to strip out the threads in some pot metal carburetor bodies or damage the fuel filter or "banjo" WITHOUT the extra torque on the banjo bolt that will be required to seal with metal washers.

Most any auto parts store should have them or be able to get them under the Dorman/HELP brand.

Also, look in the plumbing section of hardware stores and "home centers" for an assortment similar to the one at the link below that they will sell individual pieces out of.

(Those plumbing fiber washers may not carry a label that they are "fuel approved", but I have used MANY with no issues., see to be made of the same stuff the original washers were made of.)

Go down to your local hardware store and check out the plumbing section. They will have many washers made of different materials that will work. I think mine has a couple of nylon washers or maybe one fiber and one nylon.

Sorry for dumb dumb question but are all fiber washers gas resistant or is there a specific fiber type used for gas?

Any fiber washer will work as long as it is a hard material. Gasket paper is too soft to handle the movement of the bolt as it is tightened. Avoid any type rubber washer.

If there is an old school hardware store nearby, one with the aisle of specialty drawers, they should have fiber washers.
