Has anyone tried increasing the fuel pressure on there om617?
 

Recently been reading about performance benefits around increased fuel pressure.

The Fuel Return Banjo on our IPs contains a check valve that impacts fuel pressure.

The earlier om617's were adjustable, unfortunately mine is the later sealed type :(

Here's a page from the maintenance manual, which contains factory fuel pressure values and adjustment procedure.

bar to psi conversions:

0.6 bar = 8.7 psi
0.8 bar = 11.6 psi



I figured it would prob. be a good thing to verify exiting fuel pressure, before making any adjustments...so I picked up a gauge.

Being able to check pressure with only a glace seems like a nice addition :)


I have an early adjustable banjo on the way...now just need to get some fittings to plum this thing.

anyone else running a pressure gauge under the hood?
