In my '68, one year only, which turned out to have vapor lock issues due to whomever removed the air pump, after Porsche petitioned the US agency controlling thr new for '68 smog sniff tests, and received an exemption to the rule, allowing the removal legally, but the access hole for the steel tube plumbing to enter the end tins on each side, was left open, allowing the 'cooling' air, now heated after moving through the oil cooler, became the heat source causing my vapor lock condition. These fuels here, are so volatile that with any engine heat they can evaporate the float bowls dry, at an extended refuel stop.

Perry, I have run electric 'boost' pumps in my air cooled cars, since before the much more highly volatile PC 10% ethanol fuels hit the US market. also note 180° tubing for easier routing )

Complete installation kit includes: wire, override toggle switch, installation hardware, and instructions.(In progress, also added dual circuit master cylinder.

The Aeromotive FPSC does not reduce voltage! The FPSC emits a pulse modulation signal that is harmless to the pumps motor. Avoid any device that reduces voltage to your fuel pump. LED indicators confirm correct ignition signal hookup, verifies activation of the manual override circuit, and indicates when the circuit is providing full voltage to the pump.Complete installation kit includes: wire, override toggle switch, installation hardware, and instructions.View Installation Instructions Download Instructions for P/N 16302 (gen1 FPSC).This product is not legal for sale or use on emission-controlled vehicles except when used as a direct replacement part matching OEM specifications.Billet 6061-T651 aircraft aluminum housing, protected with a beautiful bright dip black anodized finish.A solid-state transistor circuit, rated up to 40 amps, replaces the relays recommended in most fuel pump electrical circuits.LED indicators confirm correct ignition signal hookup, verifies activation of the manual override circuit, and indicates when the circuit is providing full voltage to the pump.Avoid any device that reduces voltage to your fuel pump.Its like an automatic transmission for your fuel pump.

When demand increases, the FPSC returns the fuel pump to 100% duty cycle for maximum flow. At low demand, the FPSC slows the fuel pump down, reducing the chance of suction side cavitation and vapor lock. For any brush style pump, on any type of vehicle, the Aeromotive Fuel Pump Speed Controller (FPSC) minimizes fuel heating and vapor-lock problems by matching the duty cycle of the fuel pump to engine RPM.
