I mounted the fuel pressure regulator on the driver side shock tower. I mounted it so that I can access all of the fuel ports to make adjustements and such. I decided to use the -6an fitting on one of the output ports of the fuel pressure regulator, the other output is blocked off. By doing that, I can use a couple of lengths of -6an hoses and fuel filter to connect to the edelbrock carb. The input port of the fuel pressure regulator uses a 3/8" npt to 3/8 fuel barb. The output of the mechanical fuel pump uses a 1/4" npt to 3/8" fuel barb. I used a 3/8" rubber fuel line from the mechanical fuel pump to the fuel pressure regulator. The fuel pressure regulator has a 1/8" npt port for a fuel pressure gauge, and I installed a gauge in that port.
Right now, everything is installed/connected and ready for a pressure test/engine start. Its raining today so I will hold off until tomorrow.

| Top view, -6an hoses from carb to fuel pressure regulator. I will have to wrap areas of the SS hoses so that other hoses and areas do not get damaged by the abrasiveness of the hose. |

| Edelbrock 8190 fuel pressure regulator installed. Outlet port with a -6an male to 3/8" npt male fitting. Inlet port has a 3/8" npt to 3/8" fuel barb. Gauge port has a Fragola 0-15 psi gauge that I already spilled gas on the faceplate! |

| Heres a shot of the mechanical fuel pump to fuel pressure regulator. At this time I am using a rubber hose. I would like to replace that with hose with -6an fittings(doing research to find the right length hose) |
