The International Cessna^® 170 Association

While draing the gas from my fuel tanks, to replace fuel tank hoses and gaskets, I found the fuel selector valve will not shut off in the closed position. My valve is the late model illustrated on pg. 106 Fig. 64 of the 170B Parts Catalog.

I have assumed the O-rings are gone. But before pulling the assembly out of the plane, I am seeking advice from others who may have had a similar problem and repaired it, i.e. removal/re-installation procedure and parts to examine for potential problems.

Also, need a parts source for the fuel valve cover gasket (PN0513125)

See my previous post titled: Fuel valve rebuild and manual mistake WARNING.

You get all the info your looking for. The valve is a pain in the butt to get in and out but can be done. I went throught the top where the flap handle comes through the tunnel and throught a inspection hole in the bottom of the aircraft. (My A/C is probably a '52 fuselage)
Took me about 45 minutes to get it out after draining the tanks and about the same amount of time to reinstall.

Bruce, thanks for the reply. Have read your earlier forum post and it answers all my questions. Now just have to bit-the-bullet and do it.
