Fuel pressure gauge recommendations

[jrsavoie]

Does anyone have fuel pressure gauge recommendations for a 1994 Chevrolet 6.5 diesel?

I am installing a gauge Tee, sender and snubber before the fuel filter and at the injection pump.

I have a 30 psi Maxtow gauge here and could buy another to match.

I would rather find something smaller.

I haven't figured out where to mount one double gauge or a side by side.

I found an aeronautics gauge I liked, that would work just like I would like. It was out of my price range - over $1,000

This is the gauge I have now.

Something like this.
I haven't heard good reports on glowshift gauges

I like this one. Other than the price.

Any standard oil pressure gauge will work.

Do you have anything you'd recommend?

I don't have time to do things twice

Without knowing what your end goal here is I am hesitant to recommend. Where I use fuel pressure is on a couple of old tractors to monitor when the filters are starting to plug and the pump is starving for fuel. You with wanting two gauges I'm not sure of what your end goal is, so what is it? testing, monitoring, tuning or something else.

Since I'm putting one before the fuel filter and one at the injection pump. It will tell me the if the filter is plugging and if the injection pump is being adequately supplied with fuel.

And that the lift pump is supplying enough fuel.


One after the filter will tell you you're short on fuel, but it won't tell you if your lift pump is working

I would suggest that you mount one of the above style gauges under the hood and have one gauge in the cab if you are worried about size. The above gauge has contacts that can set off a light in the cab if there is a problem.

Something is wrong if you're plugging filters.
