Rusty,
I searched my files (cardboard box) over
the weekend and found the receipt for the fitting I used. It came from www.anplumbing.com. The interesting
thing is that their p/n is 991995. It looked like the one in the link I
gave earlier. Apparently, the fitting you have seals, I’m just
unsure if it is the one made for that filter. If it doesn’t leak,
then I suppose it will work. The good news is that they’re only
$5.95/ea.
I believe this is the correct fitting
because if you look into the female fitting on the GM fuel filter you will see
a shoulder at the bottom of the threads. This is where the o-ring
seats. From what you’ve said, it sounds like yours seals up at the
top of the threads. If it seals, then I guess all’s well. On
GM vehicles that use this filter, the fuel line is made to take a small o-ring
that seats at the bottom of the threads.
From what I’ve researched, this
fitting is used on “Saginaw”
power steering pumps and some TBI efi systems. Hence, the name Saginaw fitting. The
description in the anplumbing.com site calls it a Fuel Injection/Power Steering
adapter, Male O-ring Seal.

I had to
search forever to find a picture of a Saginaw
to AN6 fitting. I found this picture at the Jegs website (http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=1514&prmenbr=361).
You can clearly see the little o-ring on one end. Does the Earl's fitting
have that o-ring?
Hi Mark,
Well, I don't recall what the fitting looked like, but I
don't think that was it. IIRC, the o-ring at the outer end of
the threads, just under the hex portion of the fitting.
Next question, what makes you think you need this Saginaw fitting? I
got the part number for this fitting from a site that sold earls
fittings. They sold the normal earls filters, but also sold the GM
EFI filter in a combo with two of the earls fittings that I quoted.
Both my filters are on the output of the pumps, so they see pressure, and
they've never had any leaks. I just replaced the filters a few weeks
ago, and still no leaks.
