Petrol Pump

 The standard Austin Seven mechanical petrol pump should be adequate for my 3x stock horsepower twin SU petrol guzzling monster. 

The old pump was brand new at the last engine rebuild from A7 workshop. It has 3 problems.

1) It leaks oil from somewhere despite making numerous gaskets for it.

2) Poor starting from cold as the engine has to turn over before it pump delivers any fuel

3) It fails at high temperature on a track day, the thing just stops pumping. The main reason for the upgrade.

The advantages of this pump are as follows

1) Improve cold starting

2) Increased capacity

3) Mounts at the rear stated as ideal application

4) Improved my oil leaks

A blanking plate was needed to remove old pump permanently from the engine, that was fashioned out of 10mm alloy plate.

Here is an Index page for the build
