Had a concerted hunt in the garage and found it
I have uploaded a picture of it but I'm not sure how to display it in this message.........
Maybe this will work.........[img]http://datsun1200.com/modules/myalbum/viewcat.php?uid=-1[/img]

Below is Stirlingmac's Nizmo oil pump

So the nismo pumps exist, where do they come from?
I've been thinking about hacking the high volume pump, what was done to keep the spacer aligned so that it doesn't bind up ? I think the spacer could be made and welded to the pump body and the whole thing made true again, that would be better than having a floating spacer there.

( this is starting to sound expensive where can i get a nismo pump?)

I got mine back in 74 from the local Nissan dealer.
The part number is 15000-25722
Good luck

hi as far as i know there is a hi volume oil pump available from ( NISMO PARTS .COM ) part number 15010-25720.

sly old fox...

Well from what I can tell they're NLA but if found here, they're a small fortune:

Holeee crap. The price on that one [see link] is somewhere about $650,....... US.
Thats a bleeding lot of semolians for an oil pump.
