That looks like a really good idea. Can you elaborate on the VDO stuff? Would I be able to obtain your Semmler Gauge saver in the U.S.? On the VDO stuff it looks like they are just oil sending units for cars essentially. The problem I have with that is on some applications we may run as high as 100 PSI with a surge pressure of 120 PSI. An example would be where we're running 100 PSI streaming liquid fertilizer at high volume. We run out of fertilizer so the flow control opens all the way up trying to keep our flow rate up as we shut down to re-fill. When we start again, because the flow control is initially all the way open, it will briefly surge to 120 PSI. I don't know of many vehicles that have oil pressure gauges that go up to 120 PSI.

Thanks for the info on that. It's much appreciated.
