I just finished up an install of -10AN supply and -8AN return fuel lines on my M818. It replaces push-lock hose and fittings I installed in 2010. There was nothing wrong with that system I just thought this looked cooler. The braided nylon/steel hose and all the black anodized fitting are Made in USA products from Fragola Performance Systems. The hose separators are from Billet Specialties. I replaced everything from the left tank (primary tank with my fuel storage system) to the filter, filter to PT pump and from the hard return line back to the tank. While at it, I also replaced my priming hand pump, and all it's associated tubing and fittings.
The -10AN to 3/4" inverted flair adapter fitting on the fuel tank is a Speedflow product from Australia, but I was able to order it through the big auction site near the Bay.
In order to neatly transition the return line to a -8AN fitting, I replaced the "unobtainium" Cummins issued tee with a non-compatible 45 degree flair with a custom tee. The custom tee consists of a 5/16" inverted flair (return line) to 1/4"NPT male fitting, 1/4" inverted flair (cooling line) to 1/4"NPT male fitting and a 1/4"NPT male to 1/4"NPT female fitting all attached to 1/4"NPT female tee. With this set-up a -8AN to 1/4"NPT female adapter can readily be installed.
A test drive around town today and all was good with no leaks and normal throttle response.
