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. |

I've got a 3.0 with webers and mounted my pump up front. It's a facet blue top. Not the small facet. Althought I have a fuel cell it's mounted below where the stock tank would go. I have a Fram filter between the cell and pump. I made a steel line from the pump through the tunnel to the engine compt. This was done before any ss kits were on the market. Check with Chris Foley at Tangerine Racing he can make the ss line with an fittings. You'll just need one unless you plan a return line. A fuel regulator near the carbs would be good too...Here's the regulator/pressure gauge.

QUOTE(jt914-6 @ Nov 23 2010, 02:47 PM)  regulator/pressure gauge. I was just working on this last night - now I am concerned too. My plan was as diagramed below. I was not aware that a return line was needed. I based it on what I *thought* I saw on many 911's, as well as the pic above. Looked nice and clean. Is this incorrect? My carbed 2.0 ran the cheap Faucet pump for 15 years with no problems - although the carbs were plumbed in series verses going to a central distribution and then branching off. Attached image(s)
