Good place to mount an aftermarket fuel pump? Options

[Tdskip]

I used Jawja's picture as a template and put my replacement pump in the same spot. I've had no problems since installation (once I unkinked the fuel line under the gas tank).

Thanks - how did you get the mounting bolts on to the firewall?

I used a probably unconventional, non-mechanic, low-experience approach. I decided exactly where I wanted the pump and I had a clamp for the pump (my memory of where I came up with the clamp is cloudy). I drilled a hole thru the firewall from the engine compartment side (actually a double wall I discovered, shows you how little I know about our 914s) and thru the back pad behind the passenger seat. Then I hole-sawed from the passenger side bay back pad so that i could put a nut on the bolt that held the clamp that held the pump. I covered the hole behind the passenger seat back pad with some heavy big electrical tape. Not the most elegant solution but WTF McMark moved to Michigan and I was on my own.

Hey - it worked and you got to drive the car. Sounds good to me!

Thanks for following up.

Steve - I had a chance to look at your link, the winery looks fantastic!

Thanks. My wife Carole did the website. You can also follow Lagier Meredith on FB. We're releasing our 2016 wines today!

I mounted mine to the firewall over twenty years ago. I removed the interior back pad and drilled two holes. Used very big flat washers inside with the bolt head. Created a small bracket for the fuel filter which makes changing easy.

I used to have vapor lock issues but since moving it the new location over twenty years ago I have never had another vapor lock and I live in the very hot humid south.

Since this picture was taken, I replaced my cooling flaps with new ones from 914rubber.

I am doing this right now. same spot. trying to see how you routed your fuel lines?
I have new stainless lines in. the return line goes no where. the feed line is slightly longer and I was going to cut it 4 inches shorter, then have short hose to filter, short hose to pump, then out.

For mounting, I want to use the rubber isolator mounts, but I don't think the threaded ends are long enough to reach through the firewall.

The cleanest job I've seen is that done by simonjb. Here is a pic from his reassembly thread post #1. I may get a couple of SS U-tubes like he has and redo my fuel line route. Or maybe I'll just drive it as is....

That’s perfect. Thanks.

Where does one get stainless steel tubes like the ones shown? Any time I've tried to bend tubes that much they get kinks in them.

Similar to the 928 set up actually.
