Does anyone have a source for the copper washers for the banjo fittings on
the fuel pressure regulator?
I hope to replace the hose barb banjos on my fuel pressure regulator with
AN-4 sized banjos that I have acquired from a local auto racing supply house.
They could supply the fittings but no copper washers.
Anyone care to comment on the plan?

Bob,
We evaluated using AN banjos and here are our findings:
The Rotax banjo fittings are for use with M10x1x19 banjo bolts per Rotax
parts manual. You can buy the 10mm banjos with AN-4 flared attachments from
Summit Racing under the Aeroquip or Earl brand. The washers are 10mm "crush
washers". You can get them from Lockwood or you can get aluminum ones from
Summit. After all the research, we decided against this mod for the following
reason. The AN-4 ID is 4.35mm while the OEM banjo ID is 5.85mm. The mod would
reduce the ID by over 25%. The effects to the overall performance is
unknown but we do not want to find out the hard way. Perhaps you can ask
Lockwood
when you attend the maintenance course and report back.
