Interesting -
At
http://www.equipmax.net/baldwin/cgi_...empartid=GF133 they say "GF133 Cross to Baldwin PF860" so the Baldwin element may repalce two slightly different AC elements.
They also give dimensions for the PF860 as: Fuel Element Fits: GMC, White Trucks Replaces: GMC 854435; White 871646 O.D.: 2 7/8 (73.0) I.D.: 17/32 (13.5) Length: 2 1/8 (54.0) A. Gskt.: [2] Attached F. Gskt.: G338 UPC: 791440009431
A quick search for price in North America came up with $9.02 each (less in cases of 12) at
http://www.baldwinfiltersrus.com/bal..._lookup/PF860/. I have no experience of the seller.
On follow-up, I checked the Baldwin catalog for off highway applications and found that the PF860 is almost exclusive to GMC/Chev applications on a variety of engines between 1957-1965. 283 V8, 292 6 cyl, 302 6, 351 V6, 503 6, 427 6, 360 6, 348 v8. There is also a lonely reference to a White/GMC application, remembering there was a period with GM owning White. The only cross reference found to another filter was to the AC GF133, used in an AC GF30A housing.
For the trivia hunters out there - the only non-GM related application found was for a Chris Craft boat (and that might have been GM powered).
