Well shoot! Guess I better find senders for water pressure and boost. I have poly lines running to the helm for both these gauges.

Totally different situation than running fuel to your helm. I was given 2 mechanical fuel gauges 10 yrs, just never had the balls to run fuel to my helm after having a poly water pressure line leak. They are still on the shelf.

Run an isolator for a mechanical gage so fuel isn't plumbed under the dash/helm.
Leaking boost pressure or water isn't as dangerous or flamable as fuel is.

Instructions
This isolator is installed in the pressure line between the carb or fuel pump (where you normally pick up fuel pressure) and the fuel pressure gauge. It has a diaphragm that prevents fuel from reaching the gauge (inside the driver's compartment). The driver's side of the isolator and the line to the gauge are filled with a fluid that transfers the pressure to the gauge.
