Part # PA215
One of the hardest things to measure is the fuel pressure on a TBI unit. Use this adaptor to connect a pressure gage to any GM TBI inlet fuel line. It screws into the 15mm inlet port in a TBI unit, and your inlet fuel line attaches to it. 3 pressure outlet positions allow a suitable location to connect a fuel pressure gage line to the adaptor. Sold with or without pressure gage.
