Fresh from winters hibernation, took Z out for a short ride. Hit a mile stone of 70,000 miles. All good until I returned home and found my recently cleaned motor had oil sprayed on passenger side of motor and firewall. Found the pump decided to blow oil out of the weep hole. Over the winter I bought a new Nikki fuel pump, rebuilt the top half of the original pump. The bottom part containing the rubber shaft seal appeared to be fine so it wasn’t changed. Cleaned up the mess then removed and disassembled pump, sure enough the seal was torn.. Luckily I saved the remains of the donor fuel pump, swapped out the seal and reassembled, hopefully it last another 54 years.

What exactly was the "donor" pump for?

Bought it off eBay, listing was for “BRAND NEW NIKKI FUEL PUMP 271070” for $100. Not sure what it was originally for. 
Pump only had 2 mounting holes.  I just used the guts to retain my original pump. All pieces matched fine.

Looks like jdm-car-parts sells an actual rebuild kit, for an eye watering $125.

Thanks !

The two hole pump is for L16/18/20. Four banger.  Great donor for internal parts. 

I once bought a Toyota fuel pump that was also an organ donor. I suspect that design was used on many Japanese cars in the day

The only thing with a donor pump you need to be very careful when removing the rubber seal, one nick and you’re screwed.

To bad rebuild kits are a rare item these days. Crazy how an entire pump is cheaper then a kit..
