I found a mechanical fuel pump for sale for carbeurated 914's on the automotion sight, but I've never seen one before on a 914, VW yeah.
http://www.automotion.com/porscher-fuel-pu...-1970-1974.html If it actually fits I think I'd like to try it, but, I don't wanna throw away $120 to find out it only works on a specific engine block produce only during the month of August for blue 914's with camel interiors. Can anyone fill me in? |

All 914/4 engines used electric fuel pumps.
There is a un-machined boss on the left rear of the engine for a mechanical fuel pump that was used on the VW Type-IV. That is what the pump would fit. Unless you use a bus case, that pump won't work for you. |

We dont have any such thing.... |

When Eckler's bought Automotion, the level of knowledge on Porsche parts went downhill fast. This is not a correct part for a U.S. spec 914. There 914s sold in other markets that had two Solex single barrel carbs, but I'm not sure whether they used electric or mechanical pumps.

We dont have any such thing.... It probably won't clear the 914 heat exchanger, and being right above the heat exchanger would probably cause vapor lock. With electric pumps, especially carburetor pumps being so cheap, why would you want to put a mechanical pump on the car? |
