Early type Bosch Fuel pump Rebuild

[porsche passion]

Evening all,

I managed to free up my pump today that was partially seized. During my shenanigans I knocked back the peens that hold the case onto the body. Sadly I still couldn't slide the casing off. It wouldn't budge at all! I tapped it back into position and managed to test the pump. Its now pumping away happily, but the fuel seems to be leaking out from around the casing! Arghhh.

If anyone can point me in the right direction to a rebuild video, it would be most appreciated.

Many thanks
