Petrol tank thread size/type ?


Recommended Posts

If I change out my fuel line to something like this braided system

can someone tell me what the thread size is on the fuel tank outlet on my ‘59 3a  

 

Thanks

See your Aintree Post 

I have not checked a fitting but I think it is 1/4 BSP threaded.  Are all your fuel pipes to the pump 5/16" diameter?

With a long flexible hose from tank to pump your car will be like a TVR....regular PITA when the hose securing clips break, the pipe drops, and snags on a passing bit of road.  For me the rigid pipe is a far more secure method.

Here is the joiner (item 30) stating 1/4 BSP for 5/16" pipe.  https://www.vintagecarparts.co.uk/products/438-equal-ended-union-five-sixteenth

Moss is cheaper for the joiner (060172) https://www.moss-europe.co.uk/union-5-16-060172.html
