1992-1996 Corvette LT1 / LT4 Optispark Distributor Vacuum Harness

Regular price $ 103.87

Replace your worn, heat damaged harness assembly with our correct micron filter, check valve, fitting, and hose assembly for a GM ventilated Optispark distributor.

Our harness assembly has the correct vacuum orifice providing optimum vacuum flow without distributor damage. This however, is not an original equipment vacuum harness  from the manufacturer, we make them using high quality vacuum hose, fittings and valves, as close as possible, to the original equipment specifications and appearance. Variations can be found due to component availability. 

INSTALLING THE VACUUM HOSE ONTO THE DISTRIBUTOR CAP CAN BE DIFFICULT WHEN AMBIENT TEMPERATURES ARE BELOW 85 DEGREES F, WE SUGGEST USING WD-40, CRC OR A NON-SILICONE BASED LUBRICANT TO EASE INSTALLATION   

Can be used as replacement vacuum harness on Petris Enterprises Inc. 1992-1994 Corvette Application Opti-Spark Distributors part numbers 0457792 & 0457793
