Hey guys,

Got to play around with my 914 yesterday. With the help of my neighbor, we were able to figure some things out.

The fuel pump is mounted in the wrong spot. Mine was the one that was zipped tied from a previous post. Really stupid. It should be mounted on the passenger side fender area under the car from what I can tell. However, those rubber mounts at hold the bracket on are broke. No way to attach it back. Pelican parts does not have these any more.

Is it safe to install it in the engine compartment underneath the PCM or does this area get to hot? Any other places you guys would recommend?

Thanks,
Jason

Firewall underneath on the passenger side. Perfect location.
There are a few threads on the subject.

Definitely NOT in the engine compartment.

Hey Jason,

Do yourself a favor now, & just do the factory service bulletin's relocation of the FP to the front up behind the steering rack cover & below the fuel tank to the passenger side of where the fuel lines exit the center tunnel on the FRONT trunk firewall, so you can avoid the hot start/vapor lock problem.

Auto Atlanta sells the kit including rubber isolator mounts.

Do a search for topics, as it's already been discussed on here several times this hot season ... as it is repeatedly every year.

Search or Google is your freind!

Good Luck!

You can get the pump isolators from aircooled.net or most AC VW shops.

Thanks guys! I will definitely look into the relocation in the front.

Went to AutoAtlanta.com and they had it for 50% off. Thanks again!

My pump has been in the engine compartment to 14 years. Hasn't been a problem.

This has been debated many times on this forum. Front or Back. Both are okay. Back on Firewall is much easier and faster to do.

Located mine twenty years ago on firewall with no problems. Vapor problem gone! Much easier to change fuel filter too.

Elliot, you're saying the FP in the yellow 6 was in the engine compartment?

Jawja,

Thanks for posting that fuel pump picture. I found it last year and used it as the model for how I installed my new fuel pump (pic of my installation below). I didn't have vapor locking issues but my old fuel pump quit after sitting idle for several months while I installed SS fuel lines.

There was an October 1973 factory service bulletin (#213) on this subject, but it did not recommend relocating the FP. It was about redirecting hot air away from the pump area and insulating the fuel lines (with asbestos cloth!!!).

Note that the bulletin was issued near the beginning of 1974 model year production. It was not until the 1975 model year that the FP was relocated to the under fuel tank location.

Jeff, I would have been happy to leave the fuel pump in its original position but this was not possible if you switch to a 2-port pump (as shown in Jawja and my pictures). And lack of availability of the original 3-port pumps forces the switch to the 2-port pump and I'm not aware of a 2-port pump with both ports on one end like the 3-port configuration. Do you know of such a 2-port pump?

Both pictures show a two port fuel pump and mounted on the rear fire wall. I have had mine there for 7 years and driven in over 110 degree heat and no issues.

It is less work to locate it there than underneath the rack cover IMHO.

I mounted mine with riv nuts and the stock hardware.

Your choice.

Negatory on that.

Maybe you can help me source the NOS asbestos! Sweet sweet asbestos. I can quit anytime I want.

Airtex part number E8445 is an aftermarket 2 port pump that provides the same pressure and volume as the stock 3 port pump. I have been running one on Betty's car for about 6 years now with absolutely no issues.

Clay, is Betty's car running the stock FI?

I just installed a Bosch 69133 that I bought from Amazon but they don't seem to have them anymore. Your Airtex seems to be a good alternative.

I sold the yellow six years ago. I'm talking about this used to be yellow type four. You can just see the pump and filter at the bottom of the picture. I will NOT argue this subject. I'm just saying that it has worked for me for a long time.

This is exactly where mine is. On the rear fire wall on the passenger side.

Been there for six years no problems.

No arguments here

Carter pump for carbs mounted on front alloy crossmember easy to mount and disconnect the tank if needed ,easy.

It is definitely up for debate but it would seem the "Best Place" to mount it would be up front where it eventually evolved and was placed by the factory in later models.

For ease of application relocating somewhere in the engine bay may be easier and stop the vapor lock issue, but in the case of a complete restore I would pick the forward position, or maybe an adaptation and put the pump in the fuel tank where most modern vehicles have there's.

The cooler the better.

That pump pictured is NOT IN the engine compartment. It is under the shelf in close proximity to one of the stock 4 locations. Other than pointing out your error I have neither the time nor the inclination to debate the issue with you.

To chime in here, mine is in the coolest place possible.... inside the fuel tank! Nothing better than having the pump liquid cooled.

While you moving the fuel pump to the front, you should strongly consider replacing the plastic fuel lines with stainless. Tangerine Racing has what you need to do that. A bit tedious but worth the trouble.

I've done both the front trunk kit and more recently the firewall installation on Dad's car. I see no problem with either, except the front trunk location was a PITA with taking AX gear in and out every event without hitting it.

consider the 75/76 location and cover to keep things safe.

As far as the location goes, to me the firewall is fine, but I too moved it up front and I installed a few reusable or cleanable racing filters...

Rick Olah did a nice 75/76 conversion on some car...he posted pics here, it was a really clean way of doing it.

Rich

My guy put it here. Is it good to go? The filter slides out easily for changing.

Was there a better choice?

Mine is also mounted as in the previous picture, but I used some rubber isolation mounts to quiet the pump and installed a switch (with a relay) to turn the pump on and off. I think the front location is an easy choice (especially with the carbs on my -6s.

I just through mine away so over rated

Factory Mount
Easy access, from the front trunk

Where was it 15 years ago?
I assume this is your black car? I didn't know you had that one longer than the Zonker or others.
