Oops, typo’d the p/n.  It should read 991955.

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.
