Best guages? Add a vacuum guage also?

Postby mortarsprayer » Sat Aug 16, 2008 2:01 pm

Hello Listers,
I am wondering about which gauges to order for my conversion.
The first gauge will be a temperature of the fuel right after the FPHE
The second will be a pressure gauge near the same location similar to Sun's install.

I am wondering if a vacuum gauge right before the lift pump would also be helpful.
Any suggestions or guidance would be appreciated.

Thank you,
Nolan

Hello Sun,
One more question. Is a 15psi gauge enough for the lift pump pressure on the Dodge? Here is the gauge I am about to order;

No you need 50psi for a 94-98.5 cummins, since they hit 35psi often. Its hard to guess when you don't say what its for, put it in your signature.

If you do pressure you don't need a vacuum.

Thank you SunWizard.
I just updated the Signature.

In the same style that matches my other gauges, I see this 0-60psi Boost gauge:

Other than the annoying BOOST tag on the front would there be any difference from a fuel, air or boost pressure gauge?

Can boost gauges be used for fluid applications? I know little about auto-gauges, but I thought that a boost gauge was for turbo/air intake.

Rather than call a manufacturer I thought I would ask here, now that it has been brought up. Some boost gauges will read from 15inHg (vacuum) to 45psi.

Thanks for the reply. I wrote to Auto Meter to confirm there is no difference other than the lettering on the gauge. I also found an inexpensive alternative:

These gauges don't match my others and don't read as easily but the price is right.
