Fuel Pump Options

Post by bbolander » Tue Jan 03, 2017 8:01 am

It would be great to add to edzz's "Info for the new guys" thread for updates or changes to the Parts Reference List, but without all the discussions to arrive at the options that have been proven. So, let us know if you've found any of these to work well and recommend. A VW thread talked about lots of problems with the Airtex pumps, lever pins falling out!

NAPA's website doesn't list the M60175 fuel pump on the reference list any longer, so I did some searching and believe these are available options for fuel pumps. A VW thread said NAPA's website sucks and you still might be able to get the M60175 from NAPA. Does anyone know?

First, here is the SAV OEM replacement:

And here is the late 60's - 70's VW pump that looks the same as Pinz OEM except the top section is rotated 180 degrees.

Here is the Carter M60175 that is probably the same pump that NAPA branded as s their's but no longer do. Available from Summit Racing:

NAPA lists 2 pumps when I searched M60175 that appear to be Airtex 1071 and 1072. They appear to be the same except the top fuel line orientation.

There also is the SAV euro replacement pump, with the parallel nozzles. Can't add another picture to this post, I'll do it on another post.

Let us know what you've found works.

Other than it's more expensive, is there any reason to choose an aftermarket pump over the SAV OEM pump? I like bringing mine back to original and don't mind spending the extra money.

I've rebuilt a few of the OEM fuel pumps and have limited experience with the aftermarket pumps, but IMHO the original pump is much better overall build quality then the aftermarket offerings.

I didn't realize I had this option, but in the NAPA M60175 box the previous owner gave me is the OEM fuel pump. The bottom tappet surface is shiny but doesn't look worn bad. So an option is to get a rebuild kit and gaskets to rebuild this one.

This is likely a very old pump and the prior owner replaced it with the NAPA pump 7 years ago.

Is there anything i need to be concerned about other than just a rebuild kit? Worn parts - how do I check? Any other parts I should get along with the kit to be sure it will be good?

While the rebuild kit is still available it has become so expensive in the last few years that rebuilding is really not worth it. The kit is $132.00 and a new pump is $147.00. Also there are a couple of parts in the pump that can wear or fail and are not included in the kit.
I didn't mean to suggest rebuilding in my previous post, just that I felt the original pump was a great piece of engineering compared to some of the aftermarket products.

Flip the diaphragm over and reassemble. Might save the need for a new one.

The NAPA M60175 fuel pump that a previous Owner installed on my 710M seven years ago is suspect of leaking fuel into the oil pan. I have a new SAV OEM fuel pump to install in its place.

Does anyone know whether the previous Owner would have had to modify the tappet rod length from OEM to put in the NAPA M60175 pump?

Wondering if I can just replace the NAPA 60175 fuel pump with my new OEM fuel pump without any tappet rod length issues?

The Carter M60175 fuel pump can be used as a one-for-one replacement for the stock pump.
Typically used on older 1.7L VW's. You should be fine flipping in the OEM pump from SAV.

IIRC, the manual tells how to measure the stroke to assure the proper length of the rod.

Here's what I recommend, and have been using it for years with no problem. MUCH easier starts, too! I use a Holley pressure regulator, but think that it may not even be necessary. This version has an internal filter and an anti-siphon valve.

I'm going to install a new SAV OEM fuel pump next week. On other vehicles, I've just coated the fuel pump tappet lever with EP Moly Assembly Lube. The Pinz repair manual says to fill the lower pump cavity with grease before installation.

What do you do, or recommend?

Doesn't the lower tappet lever part of the pump get lubricated with motor oil during operation?

We installed the SAV OEM pump and after a carburetor rebuild we started it up today.

We initially had trouble with the fuel pump not getting fuel to the carbs. Probably since the fuel lines were completely drained back into the tank, and maybe because the pump was just super stiff. We took the pump off and manually cycled the lever, heard suction going well. Then put it back on the engine, and used a vacuum pump to bring some fuel up into the lines. Then the Pinz started and ran.

Thanks for the recommendation. I have two pinzies. One has the OEM mechanical fuel pump and the other has/had a 12v fuel pump that was installed by the previous owner. The electric pump has been working fine until it crapped out last week. All Iʻve been doing was tapping power from one battery and then switching it to the other every other week or so. Anyhow, since it died I was thinking of buying a mechanical fuel pump from SAV but if this 24v facet pump works better then I might just go that route.

In terms of performance, how do they compare? Any reason for going electric over mechanical? Thanks.
