I used the 1.5 gallon tank from Ron's fuel injection with a Holley float bowl mounted to the side of it. Ran an electric pump from the tank in the back to keep the front tank filled. Used the small tank to supply the cam driven pump. Worked great.

Ron's Surge Tank

Used on door slammers, this tank is placed high in front of the engine to gravity feed the injector pump. The tank is fed by an electric fuel pump from the fuel cell in the rear of the vehicle. This tank holds 1.5 gallons, has 1 vent, 3 returns and 1 float bowl to keep it full. 13” x 8 1/2” x 5 1/2”
