Fuel Pump

[orforester]

So today I tried to start my long in the shop project 85 K100 RS converted to RT.  Starter worked fine and the fuel pump worked, but I heard this funny noise after letting off the starter.  So I opened to fuel cap to see fuel coming out the top of the pump (between Aluminum cover and the black plastic top) in several areas in a small stream? 

So I drained the gas and took the pump out and used a screw driver and dead blow hammer around the edge of mounting cover, to seal it again (or so I believed).  Replaced it all again and started it again, same thing? 

I have replaced the fuel line and filter, double checked the direction of the fuel filter, in case that was plugging it up.  It was correct flow.  I have replaced all the outside fuel lines and vacuum hoses over the winter, so everything is new.

Is there something I am missing? 

Mine is the old style pump with no hose off the filter basket under the pump and again it is an 85 so has the fuel sender in the front.

Time for a new one?

Or search a new gasket, if you want to keep the costs down.

Ok Inge, is there a link on how to "undo" the aluminum case and then I can search for o ring, and likewise put the cover back on, tightly?? 

Thanks

Fold back the alu at the top of the pump, use a suitable dia. plastic tube or similar inside the alu in the bottom of the pump.

Put the plastic tube at a table (not in the living room) grip the alu housing with both hands (rubber gloves helps) press, push, knock the internals out of the alu housing......to only reach the top gasket it isn't that much needed.

If you don't find a o-ring, you can do as in this link (don't know if the result was successful, tho).

Alternatively, you can stick a Ford pump in there And be done with the expensive OEM once and for all. They're cheap and mine has been going for 6 years now.
