Unknown origin.

However, since the A12 uses standard size flange and threads (a Ford number F1 filter fits), you could theoretically use a Ford adapter with a cooler core from any vendor. The stock pump is probably adequate for just adding the cooler. To use the F1 filter you need to grind about 6mm off the block (I'm referrring to the early A12).

A cooler is useful for constant high-speed use.

Where did you get the adaptor from Melb datto dude I want one?????

Gents, I have these similar items which I'm just about to advertise.

I am selling a genuine Nismo A-series oil gear pump and a oil cooler, Earle's sandwich plate and stainless steel braided oil lines.

Photo's of these items are in my photo album.

Gary.

how much and do you sell them seperately??

The oil pump has just been sold

Would like to get $150 for the oil cooler assembly, you can't see it in the pic , but the adaptor bolt is in the sandwich plate.

The sandwich plates are available from Earle's and the oil coolers are available from Jeff Taylor, Pirtek made up the hoses for me.
