You're the type of owner that wants the most accurate systems information you can get, so you run mechanical gauges. You're also the type of owner that disapproves of having fuel inside the cabin of your truck. There are options to ensure you can use those mechanical fuel gauges, while keeping the go sauce out of the cabin. The ISSPRO Fuel Pressure Isolator is here to keep the fuel where it belongs, while feeding you the critical accurate information you want and deserve.
Don't feel however, that you're limited to just fuel pressure. If you have fluids you want to monitor, tie this in, run a 50/50 mix of coolant and water to the gauge itself, and you are off and monitoring.
