As Richard said, the fuel pumps for mfi are different to those used with carbs (& have different fuel pressure outputs).
This is what the correct mfi pump looks like:

The 69 T had an electric fuel pump, same place as the S and same basic design, just a different spec.knapmann wrote:
I still dont know where the wiring for the fuel pump routes, I assume that if the T had a electric pump as well that it was placed elsewhere on the car? If it had a pump in the same position as the S then i sould have factory wires there in any case. I cant see any way to route the wire (without cutting a hole) other than through the smugglers box.
Excellent thanks for the picture. Its obvious when you know I suppose. I can see in my smugles box there is a rubber bung plugging a hole through to the area you describe. I assume the wire goes through here? I cant see any other way for it to go. In any case I'll be happy routing it through here.inaglasshouse wrote:The 69 T had an electric fuel pump, same place as the S and same basic design, just a different spec.knapmann wrote:

Please see attached pics. Pump is item 35 on the PET diagram.
The loom from the tank sender has another branch, which routes down behind the tank. This is the feed for the pump.
(Please excuse untidiness, this was early in the process of fitting the tank etc).
I believe the original routing was per my pic - just down behind the tank (not via the smuggler's box).knapmann wrote:Excellent thanks for the picture. Its obvious when you know I suppose.

Yep. Please see below for hole, and my previous post for the wiring run before it goes behind the tank.Lightweight_911 wrote:.
up to the back of the fuel tank & through a rubber grommet in the centre (just infront of your RHD smuggler's box) ...

Yes you are both right that hole is where my bung is, im not sure why there is a bung there if it would have had wiring going through there from the factory but there we go, at least that mystery is solved!Lightweight_911 wrote:.
It's a very long time since I had a '69 911E but I seem to remember that the wiring for the fuel pump ran from the fusebox up to the back of the fuel tank & through a rubber grommet in the centre (just infront of your RHD smuggler's box) ...
