mercury opitmax pressure gauge kit

[suzbass10]

Other than from mercury, is there any suggestions as to where I can get some gauges that will read fuel/air pressure on the mercury opitmax/tohautsu TLDI motors.

Thanks

I've been looking at this also and I think it shouldn't be to hard to make your own. Just get 2 good quality liquid filled gauges, some hose and get someone to fit the screw on tyre valve ends to the hose to screw to fuel/air rails. These are a very crucial tool for diagnosing problems with the opti's and would be good to have.

I use my Snap-On gauges.

Yep, you can use two high quality liquid filled FP gauges. Without the "blow off tube" you can't check for fuel in the air side easily though.

All I've ever used is basic automotive stuff you can buy at Auto Zone, for Opti's.
