Fuel leaking from aux tank?

[TomM]

The parts manual that I have (1965-1969) calls out the -1 which is what I got from McFarlane when I replaced mine. I try and stick with what the factory calls out as much as possible and makes sense. The price difference isnt all that much as you noted - albeit that you need 6 of them for a complete job.

The McFarlane parts I have used so far are have been great quality and economical. Heck, they even have an "expiration date" on the fuel level sender gaskets to help control quality.

My recommendation would be to stick with what was originally used.

To ALL. FYI, I have found a gasket manufacturer that will make the S1588-1 fuel sending unit gasket with the popular material VITON, the same as McFarland's. For about $25 each VS McFarland $36. If you replace all six gaskets it's a good savings. Currently this gasket is NOT FAA/PMA but with interest the guy said he'll go through the PMA process. The same company currently offer fuel cap gaskets for many aircraft types, including Skymaster, with FAA/PMA certificates for around $8.
Use at your own risk. Just trying to save you guys/gals some money.
