Fuel Pressure Test
« on: July 26, 2019, 02:27:59 PM »
Hey guys,

I am wanting to test the pressure on my K75 from the pump and also to the FPR.

Just wondering if this el cheapo fuel pressure gauge kit would work?

It will work but you can just make up one. Mine was made up from various pieces I had lying around plus a couple of fittings I bought from the local Auto shop. The gauge was salvaged off an old regulator 100PSI is fine but 80Psi will do.

Cheers Martin

I like your crafty attitude. Unfortunately, I have no garage and very limited tools here in NYC but might drop into my local chop shop next door and see if they have some stuff lying around that I might be able to borrow. The empty lot next to my building is full of wrecked cars that the local guys build into drag racers.

Thanks for the pic it might help me talk to them as my Spanish is really bad.

Tight arsedness is the mother of invention.

it will work fine, and is cheaper than your time to kludge one from spare parts.

just tee it into fuel line between the pump and the fuel rail.
