Mechanical fuel pump beginning to leak. 1971 350 CID. If someone has the OEM Part # I'll try to find the correct OEM replacement mechanical fuel pump, unless you happen to know a correct OEM replacement Part #.

Thanks for looking...I appreciate it. I have "some" digital parts books. I did a search on CO but it's taking forever.

 

I believe I found it in the PIM. OEM Part # 6440616. OEM Gasket Part # 3705042.

Thanks for looking none-the-less.

 

Follow-Up Question....

Since they only list seven different manufacturers does anyone have a recommendation based on quality?

AC Delco 40446
BWD 40446
Carter M4503 (I believe that's what's in it now)
Delphi MF0051
Kem 40446
Pierce M16105
Spectra Premium SP1021MP

 

What a labyrinth of gobbledy gook matching part numbers. Yikes.

 

The 1971 Engine Assembly Manual shows "Pump Assembly" as 6440713, used on every 350 engine that year. Of course, there's no discussion of what comprises the "assembly". The Jan 1972 parts book shows 6470331 for the pump, and notes that it is "less return line".

 

I'll add that alternate part numbers for GM 6470331 are:

AC 40713
Delphi MF0024
Spectra Premium SP1033MP
Carter M6108

 

Joe - Thanks much for the assistance. One reason it's always a good idea to ask questions.

 

You do realize that page from the PIM is for the inline six, right? The V8 engine section of the 1971 PIM doesn't show the fuel pump because it is installed at the engine assembly level.

 

I was researching in section 6-1 (V-8 section) & I couldn't find a fuel pump anywhere & I kept researching and found the fuel pump in section 6-2; but......I did not realize I had crossed over to section 6-2 (L-6) section.
You saved me a ton of time & heartache. Thanks much.

 

It's hotter than the *** crack of a jack rabbit outdoors so let's add insult to injury in my case. I was so consumed in finding the Part #, had I been 'paying attention' to the overall picture of the fuel pump location relative to the oil filter housing, the fact the image below actually shows an in-line six w/ oil inlet cap - I find it remarkable they give me a driver's license.

Thanks again.

 

I hate to say it, but the fuel pump gasket in that drawing should have been your first giveaway.

 

No you don't...now get off the lawn.

 

I have always used Carter pumps. The last one was from NAPA under their label.

That Carter number above is for a Chevy engine, though.

 

Thought I'd be a Maverick and venture into the unknown with some confidence in another company who purports to test their filters throughout the build process - keyword "purport".

I ordered this one from RA.

Looks like a good one.

 

GMB makes pretty good stuff (Japanese, I believe).

 

Thanks for the input.

 

I concur. I've used GMB also.

 

Good to know.

 

Me again. Fuel pump removed, old gasket had some type gasket sealer. All old gasket sealer & old gasket removed down to bare metal & cleaned with engine degreaser then brake cleaner.

QUESTIONS:
1) I noticed regardless of manufacturer they ship a fuel pump w/ two identical gaskets - this GMB is no different. Why do they ship two identical gaskets? In case you botch your first attempt or some other reason? I wouldn't think I'm supposed to apply/install two identical gaskets on top each other.
2) Should I apply a gasket sealer to both sides of the gasket (including the new fuel pump)? Fuel pump doesn't need a gasket sealer? If I should apply a gasket sealer, here's what I have in my arsenal at the moment. Suggestions?

a) Permatex - (Green) Gear Oil Specialized Formula Gasket Maker - What I generally use for sealing differential covers, transfer case covers, etc.
b) Permatex - (Blue) Fast Drying Hard Setting Form-A-Gasket Sealant
c) Permatex - (Gold) Ultra Copper Advanced Formula Maximum Temperature Gasket Maker
d) Permatex - (Red) Red RTV High Temp Gasket Maker

Thanks for looking.

 

I went w/ two gaskets plus light coats of Red RTV High Temp Gasket Maker (81160). Fuel pump in, AC compressor bracket next to button it up.

 

I've always speculated two gaskets in the box were for those applications with spacers.

This is my preferred method: I use only one gasket with Permatex #2 applied to both sides of the gasket, torqued about 26# with thread lock on the bolt threads as these bolts/nuts normally vibrate loose over time.

Hope this helps.....

 

All done. Torque value is 25 lb-ft. I used thread locker. I torqued the bolts to 25.467389203 lb-ft +/- 0.000000001
Thanks for the input.
