Does Di procol make drive and rail pressure gauges? Because i want them but i need to know if they have these, otherwise ill have to switch to cobalts or something.
They don't sell a gauge labeled drive pressure. I have a 0-100 PSI electric fuel pressure gauge as my drive pressure gauge. They have a rail pressure gauge that comes in a kit for the Cummins but I have also heard of guys using it on a Duramax, most likely just need to splice the right wires - fairly sure Fleece could help you with which ones.
I use the electric fuel pressure gauge for drive pressure too, and a scan guage for the rail pressure
pretty much most things you can log with efi you can watch on the scan gaugeCool, i may end up buying one of those scan gauges for the rail pressure instead of buying a designated rp gauge. Plus those scan gauges can monitor numerous things right
