I have the same issue if I leave my valve on "main". The dihedral of the wing places the main tanks higher than the aux tanks. That will push the fuel through the aux and out the overflow if your valve does not seat properly or if valve is out of sync with the selector handle. Mine stops if I turn the valve to "off"

Fuel leaking from aux tank?
Hello ALL.
Has anyone used the fuel sender unit gasket S-1588-'2' which is thinner than the original S-1588-'1'? McFarlane has them for $23 each VS $36 for the original? Their gaskets are make with Vilon a special material for fuel environments?? Thanks, BILLS PS: Cessna wants between $80-$104 each,FYI. |

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. Thanks, BILLS |
