I remember a thread on this subject where "Sealing Washers" were used on the bulkhead connectors that make up the crossover hose at the bottom of the gas tanks. I can't find those washers anywhere local. They're 1" I.D., rubber with a metal O.D. and look like large oil pan drain washers.

Does anybody know where I can order these?

You should be able to find a suitable replacement at any auto parts store.
As long as you find something with similar dimensions, it will be fine.

I would also encourage you to seal the threads with a fuel safe epoxy on
the inner, and outer side of the fitting.

No leaks

If you have access to a lathe, just cut some groves in the AN fittings that FF supplied and install O-rings. No need for any glue/sealant and easy to install.:001_smile:

Pictures?

How were you able to have a tolerance that allowed the fitting to be inserted into the tank without disturbing the o-ring yet will not leak?

If a 1" hole is made the fitting has to cut threads to be inserted. What size hole did you use?

Here's a pic of the nut still in my lathe. It's really only the o-ring on the outside of the tank that matters since fuel will always migrate past the threads...
