Just use a 911 one or are the 914 FI pumps adequate?
Thanks and hope everyone is having a good weekend. |

Are you running Webers or the Motronic? If F.I. I believe you will need the fuel pump that goes with the F.I. (IMG:style_emoticons/default/beerchug.gif)

You need to use the 3.2 pump. It was a while ago but I remember Summit had the correct pump for a lot less than the usual suspects. Then go to a speed shop and get fittings to fit.

QUOTE(mepstein @ Dec 27 2020, 07:59 AM)  You need to use the 3.2 pump. It was a while ago but I remember Summit had the correct pump for a lot less than the usual suspects. Then go to a speed shop and get fittings to fit. I’m using the GT3 pump with my DME. It doesn’t have the goofy size hose barb. The GT3 has a threaded hole instead so you can use AN fittings. Claudes buggies also sells AN fittings for the stock 914 tank. Makes connections much easier. https://www.pegasusautoracing.com/productde....asp?RecID=6119 https://www.cbperformance.com/product-p/3288.htm I used AN barb fittings with standard fuel injection rubber hose. For the track you would use steel braided lines. |

20 years ago I bought a new Audi 4000 fuel pump. It has these nice color coded screw on plastic terminals with rubber O-rings seals. (Again Audi factory) The early fuel pump location is tight. It’s super clean and I’m still running the same pump. No issues at all with fuel pressure and the car does 150 mph with no fuel starvation confimed several times..!

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
Wouldn't any external two barb (and electicial connector) in-line 30lb-ish FI pump work?
CIS needs/has a special pump, way higher pressure than an EFI pump. Where as carb pump is to low of pressure. |

Patrick Motorsports does hundreds of these conversions. Give them a call or check out there project pages.
https://patrickmotorsports.com/blogs/news/t...che-914-4-914-6 You will notice he uses a stock 911 pump. He also mounts them in the stock location on the aluminum 911 cross member. Mine is still in the 75-76 stock location. I plan on moving it someday to the aluminum cross member. The pump is pretty quiet and has not been a problem so far... |
