Fuel pressure gauge

It’s a #5 o-ring boss to 1/8 female pipe adapter. The snubber I use from 4-states is 1/8 pipe male on the inlet and 1/8 female on outlet. 1/8 inch male pipe to #6 jic comping out of the snubber. #6 swivel on each end of hose to the manifold at firewall. Then same to gauge with a 1/8 to #6 male adapter on the gauge. My 379 came factory with a fuel pressure gauge that just had red and green in the range. It needed to be maxed out to read around 40psi. It was gonna take Peterbilt in Springfield something like a month to get one for mine. So I went with a Stewart Warner that the local bumper to bumper parts store had in stock. I’m Isspro and Stewart Warner both offer a gauge that reads up to 100 psi with a chrome or black bezel depending on what you need to match. The black face and white numbers make it look very factory. Seems isspro makes the factory guages.

359 will be set up the same as far as fittings and line to the manifold as well. If the manifold doesn’t have an empty hole then get a male to male #6 from Pete. Pick a spot drill it then put your male to male in. Makes it nice and clean. Nothing is trashier than a bunch of holes in a firewall with random #### ran through it.

Thanks very much again sir for always helping out, for the manifold can I pick any empty slot and use it for this or is there a specific one I gotta run it to? Also by the way I asked you a question about the parking brake about a month ago, quick update you woudnt believe what it was, whe I got my frame sand blasted I had about an inch of sand stuck between the shoes and drum on that one that wasn’t releasing I ended up taking all of them apart cleaning them thoroughly and I’m moving again but thanks for the help on that too

This is the electric sender I use now, but you can tap into the primer pump housing here for yours as well. A tee in the line would work too. View attachment 390440
