So I am converting my '74 914 to a 3.0 with Webers and am going to run a fuel pump in the engine bay. The PO had the car set up with a big 4 running Motec injection using 3/8 aluminum fuel line setup running from the tank to the engine bay with a return line to the tank. There are presently two AN-6 bulkhead fittings which exit just below the battery tray which I will be connecting to.


(IMG:http://www.914world.com/bbs2/uploads_offsite/i954.photobucket.com-11663-1290530412.1.jpg)

I'm looking for suggestions on a make and model of a fuel pump to run as well as suggestions for mounting. There is an unused mounting bracket near the fittings which could be easily modified to mount fuel pump. My concern is that it does not interfere with the engine or be located too close for heat reasons. So that is a possibility.

I'm looking for a good pump that will run fairly quietly and will last a long time.

Any suggestions?

Thanks.

Thanks Rob,

There's a ground buss behind the passengers headlight. I'll pull power from the same place the original one was tied into (yet to be done). That wire now comes into the front compartment with the loom and then goes into the passenger compartment again, with the loom.

That "hardline" is a Seinesystem hood prop. Nothing but a fancy piece of fly rod in my book. An expensive one at that. I may have a line on a more competitively priced version but, have yet to see the samples.

Cooler Lines - In the second picture (previous post), follow the loom to the firewall. Look below where the loom enters... there you'll see the mouse door for the lines. They are modified early 911S lines as per factory GT's. They'll run through the drivers footwell into hardlines going down the rockers. Again, all as a GT would have it. I hope to get the lines this week so I can snap some more pictures.

My jack post was modified for the hard lines:

The sill supports were modified for the lines as well:

Here's the hole going into the drivers side foot well:

The heater tube was modified with an acetolyne torch and some drifts. I wanted to keep heat in the car. Saw this on a factory GT picture.
