You could always make a tool for it. Bend a piece of 40 x 5 flat bar into a shallow "U", file the notches to engage the ring, weld on a socket, an old bolt or file a square hole in it, and apply torque as appropriate.

I got it out in the end; Used a 4mm flat steel bar and carefully tapped away. The big flat blade was too sharp but the flat bar worked a treat.

Upon inspection I noticed why the fuel gauge doesn't work - the braided wire had broken. I think I might end up getting a complete new unit as the bottom of the bowl I found black plastic lodged in the intake and there seems to be a brown plastic part that is loose that must be part of the fuel return system. Perhaps this clogged up not allowing fuel to flow through the pump and thus overheating the pump. Applying 12v to the pump directly does nothing.

Because I have the 140L metal tank the fuel pump unit etc didn't line up with the access hole by a long shot so I had to use tin snips and cut an inch or so of the flooring back to be able get the unit out. Quite frustrating but anyways, better than trying to remove the tank lol


Any suggestions in where to buy the complete unit?


Cheers

The only slight issue I have is that the one I have has a 12" lead from the top going in to a female round plug. Also the top of mine is metal and I have a splade plug on top for another earth. Because I have a metal tank do I have to find a pump with metal top? Mine looks more like a Disco 1 3.5 unit as the one below.

A little pricey for a britpart.

Look at ebay again, here's another...

You could always find one at a wreckers and replace the pump on it.

Also if you get the cable for the newer pump assembly from a wreckers you can make an adaptor cable. Pump should fit the same. The extra earth is for the sender unit, the newer pump has a 4 wire plug with two earth connections. These are joined in the pump cable before other end of it where it has a 3 pin plug.

Also I keep reading that there are different pumps for the 3.5 & 3.9v8 and to check the vin numbers. What's the difference? different fuel pressure deliveries? volume etc? Is mine standard for the 93 classic? Or has someone put an earlier fuel pump in it at some stage with different wiring plug?

Fuel pressure is set by the fuel pressure regulator, on the engine. As long as your pump keeps up with demand, it will be fine. As I said, find a pump harness and make the plastic one fit.

Just found this at island 4x4;
