All Ercoupes left the factory with that valve. It’s a safety hazard NOT to have it. It can shut off fuel from the wings to the engine in case of an engine fire. You are supposed to have it wired open with breakable copper wire.

I looked, and sure enough my passengers right foot hade pressed down on the fuel shut off lever with his right foot shutting of the feed to the top tank! smoking  Hope this helps someone.

One option is to secure it open with copper safety wire, in an emergency it can be easily broken to turn off the fuel valve

I keep an FPA 28/29 kit from Then and Now on hand, in case the diaphragm fails. I still buy the gaskets from Aircraft Spruce for the pump AD compliance. The AS gaskets are higher quality.

are you sure it is the pump and not the float ?
There are no "official" kits, at least those available to us mere mortals, That pump originally came from a 34 Buick, Check out then and now automotive,

I have a Continental C-75 in my Ercoupe. The fuel pump is weak--it can keep up at 1/2, but it cannot get the float to the top of the indicator. Float is OK, visual check in fuselage tank reveals level below overflow tube. Can the pump diaphragm be replaced? Or?

Thanks, Don
