Hi there,
I'll post a picture over the weekend as I've packed up for the day but the basic setup is line from fuel dist to T connection, gauge then shut off valve and then line to CPR. This is with the banjo bolt to the throttle position reg removed entirely.
Sorry if I'm not describing this very well. There is a wide shim (maybe it's just a washer) that goes around the hollow bolt so that inserting more of those drops the pressure since the bolt is then further away from the body of the FD and the spring is more relaxed.
Then there are some mini-shims/spacers I've added that fit on the inside of the hollow bolt and serve to compress the spring more. Adding more of these has resulted in higher system pressure as more force is applied to the valve. Is that how it's supposed to work?
With the setup as described, I get a system pressure of 4 bar then when I open the valve (without power to the cpr), the pressure doesn't drop. I'm still not 100% sure what I'm supposed to do with the banjo bolt that feeds the throttle pos reg but the fact that the pressure isn't dropping tells me I'm definitely doing something wrong!
