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.
