Electric fuel pumps for early Triumph TRs :

Kas Kastner says that you need 35 gallons per hour flow for a race car.

The SUs need about 2-3 lb./square inch pressure to operate.

Insufficient flow can occur if you use a pressure regulator set to regulate at the pressure that the pump puts out unregulated. The Chief Boffin here at The High Speed Triumph Research Laboratory has experimented with this phenomenon. Makes the car run terrible.

I forget the pump brand. It was cylindrical. I had a filter before the pump. I had a fuel cell in the spare tyre compartment/trunk, so I put the pump and filter where the stock tank goes. I don't know where you would put the pump if you have a stock tank.
