Fuel tank

The tank in this special was always going to be bespoke. There was no chance of the standard Ruby tank fitting the space in the Super Accessories bodywork. I was going to get Bryn Jones of AliFab  in Wales to do it but he appears to have gone out of business. I was given the name of Simon at Sifab who does an equally good job. The drawings went through a couple of iterations but produced a good tank in the end result.

 

Jim Pettigrew gave me some help to run the fuel lines and the wiring harness along the chassis legs.

Next job is to obtain a sender and make some rubber gaskets to mount it on.

Wiring harness

The Seven Workshop sell a very nice PVC insulated modern fabric covered wiring harness optioned with flashers and dual filament dipped headlights P/N AE0346 +  options. They also provide a diagram to decode the colours but the options are missing from the diagram. The harness installed very nicely in the chassis but I had to figure out by deductions how the options were configured.

To help you should you choose to do it this way I have included a diagram modified from the original John Comforth diagram but adding the changes associated with:

* Flashers
* 12V conversion
* Dip headlights using a relay and a switch

Radiator

The 750 Special I am building requires a radiator cowl 22 3/16" high. These are very rare these days as they were fitted to much earlier cars so I took the standard ruby radiator and lopped 2" off it. Then I made custom side supports. The radiator core was also reduced in height to accommodate the new cowl. The radiator mounting brackets remain standard.

The next job is to paint all the chassis components ready for the fuel tank return. Then a test drive.
