FUEL SENDER UNIT THREAD

[Colin Cooke]

Hi Everyone,

Searched previous threads (sorry), but cannot find this information, so would appreciate some help.....

What thread is the electrical connection on the fuel level sender unit (on tank)? I think there was only one type, but just in case, this is for an RP.

All the best,
Colin

Hi Colin

I am 90% certain that they will be BA (Probably 4 BA which is 3.6 mm OD), a thread type favoured by Smiths and Lucas for electrical terminals.

If my memory serves me correctly they are BSF not BA.

Mecano screws fit

My RP sender unit ....

The electrical connection is 5 BA

The six screws to fix the unit to the tank are 5/32" BS Whitworth (same as Meccano)

Meccano Nuts and Bolts are 5/32" Whitworth

It is my firm conviction that a classic British Car is not complete without at least one meccano piece. In my case it is actually a flange which is part of the throttle linkage on the MG.

Ah yes thank you guys, 5/32 BSW, sorry for my red herring with BSF!

Hi Chaps,

That's all great info. I too, like the idea of having a bit of meccano on the car.

Thanks to everyone.

As Henry said, 
    5BA for the electrical connection and 5/32" Whitworth for the sender screws. The sender screws are available from the Autovac people.
