Shut it off after starting the engine. In the case of a mechanical pump failure, the Lucas elec- tric pump can be used to run back to port or the pits at low engine speeds, part throttle only. Kinsler vapor separator tanks are available 8”, 10”, and 12” tall; in 3” and 4” diameter. Use the tallest tank you can fit into the car. It is important that the tank have a proper internal vapor separator chamber, or the tank will fill up with vapor... this is built into our tanks. NOTE : The electric fuel pump MUST be on before cranking the engine to lubricate the metering unit. Alternate plumbing at main tank... no catch tank used. An electric pump at rear of car draws directly out of the main tank and pumps forward to vapor separator tank. Disadvantage: without the catch tank, the rear electric fuel pump will sometimes suck air, thus losing the pressure in the vapor separator tank. The advantage of keeping pressure in the vapor separator tank (which is regulated by the tank Backpressure valve) is that it super- charges the inlet of the mechanical fuel pump, thus preventing any cavitation... ideal for very hot and/or high altitude operating condi- tions. If you do not use a catch tank, then draw out of the rear of the main tank with the electric pump, to get good fuel supply under acceleration conditions. © 2017 NEVER use a “drilled block of metal” type angle fitting on ANY pump inlet hose... where the drills in- tersect there is a razor sharp edge that promotes pump inlet cavitation. The best solution is to make gentle bends with the hoses. If you have a really tight place, use a bent tube type hose end fitting.

On racing metering units, the shuttle stroke is controlled by a cam linked direct- ly to the throttles. The principal of shuttle metering, illustrated above, shows shuttle movement is reversed as the rotor turns. On a V8 metering unit, there are two shuttle assemblies and each assembly controls the fuel to 4-cylinders.
