1970 911T Fuel pump rebuild help
My fuel pump is really leaking badly. I noticed it while warming the car in the garage one day, after filling up the tank and adding a half bottle of carb , so I shut it off and thought the leaking had stopped. The next day, I went out to jack it up and take a look and there was a pool of fuel on the floor and I could see it dripping from the pump. I jacked up the front and after blowing the pump with compressed air (many, many times, with safety glasses on of course!), the fuel appeared to be coming out of the top side of the pump where the plastic electrical socket is located. This pump is the type with three lines, one to the carbs and two to the tank (in and out). This pump looks like the MFI pump, only pumping at a lower psi. I removed the pump and it is leaking where the plastic socket meets the side of the pump.
I removed the four screws and took the end off and replaced the only two seals I could get at but it is still leaking. Other than the leaking, the pump works great, it runs quietly and there is/was no shortage of fuel getting to the motor. I`ve been told that this pump may be worth fixing and that there are posts on how to rebuild this pump. I can`t find the posts, would somebody be able to give me a hand? Thanks for your help! |

The rebuild on here only explains how to fix the pump, and how to get to the brushes and all. It doesn't explain how to fix the infamous connector leak. Some company called Fuel Injection Corp rebuilds the pumps but I'm going from memory so don't quote me on it. The pump looks like the MFI pump but the output psi is different.

Thanks. I`ll try to look them up. It is looking more like I`m going to switch to the two line pump with a regulator.
BTW, You mentioned in another posting about my pump issues that you had a CD problem. Do you need one? The PO converted to MSD and I have the old CD in a box in the garage. I appreciate your help. |
