Stock Dauntless V6 fuel pump numbers and info

Some information on stock Dauntless fuel pumps:

From Ken, (oldtime)

The 1965 and 1966 Dauntless CJ uses AC 40001 pump (Kaiser # 6414989)
This pump has 2 horizontal positioned fittings.
The threaded outlet fitting (to filter) accepts 1/8" NPT.
This has a 1/4" barbed inlet tubing to accept hose.
These fuel pumps are for Dauntless CJ's without fuel return lines.
These pumps came in two distinct forms.
The early rebuildable design (pre 1966) and the later non rebuildable design (post 1966) share the same part numbers.
It is likely that rebuild kits were never produced for the rebuildable since it was early on replaced by the non rebuildable design.
It appears that around late 1965 the non rebuildable pumps become the AC production standard.

The 1967 Dauntless CJ uses non rebuildable AC 40515 (Kaiser # 6416783)
This pump has 3 vertical positioned fittings.
The threaded outlet fitting (to filter) accepts (1/4" male flare nut ?).
This has a 3/8" barbed inlet tubing to accept the supply hose.
Also a 1/4" barbed inlet tubing for the tank return hose.

I lost my proof (not noted in pre 1972 parts catalogs) but my records indicate that ...
The 1968 through 1971 Dauntless CJ uses non rebuildable AC 40926 (Kaiser # 6470633)
This pump has 3 vertical positioned fittings.
The threaded outlet fitting (to filter) accepts a 5/16" male flair nut.
This has a 3/8" barbed inlet tubing to accept the supply hose.
Also a 1/4" barbed inlet tubing for the tank return hose.

Cary,
According to your Popular Parts reference it appears that pump repair kits were available for the rebuildable version of the AC 40001.
The picture shown is generic and is not the rebuildable AC 40001.
