Low pressure light or shut down is very easy to setup, I have had a prolight in the GTX since the 80's and the Reliant has had one for some time.
Can't miss when one of these are set off, blinding at night. In the Reliant and GTX both have 20 psi sending units.
I had a company that did coatings on the gears, next motor will have done for insurance.it would be nice to be able to have the oil pump driven by a shaft without a right angle gear setup.... or get those parts hardened somehow or create an oil jet on the gears to keep them well lubed.
