Fuel Pressure Gauge

Is it easy to do?

Thank You

You can connect an adapter to the back of the fuel bowl like Maintain's set up. It is a #4 O ring boss fitting in the back of the fuel bowl and from there you can make up whatever you want.

or

you can use this type of setup: http://www.dieselinnovations.com/tec...test_setup.pdf

This way is temporary and you will need to buy a new fuel filter that comes with a new lid. In stead of using a straight hose like in the pics, use a 90* angle on the lid so you can close the hood. Make sure to get enough hose to run the gauge to the cowl so you can read it while driving.

We did a temp setup one time where we just hooked a hose to the filter drain pipe and clamped a gauge to it then opened the filter drain, quick and dirty but it worked, I was surprised the drain hose didn’t blow off the valve. Tapping the filter lid is a neat idea but those filter lids cost $$ to replace. I like plumbing the gauge into the head so I can see the pressure as close to the injectors as I can, in case something in-between is stopped up.

I now got an electric pressure gauge mounted in the cab in the over the mirror pod. It was around $10 on ebay with sensor and all. Not at all accurate but works, sometimes. I plan to upgrade in the future but nice electric fuel pressure gauges are pretty pricy.

I’ve installed two liquid filled industrial 0-100 psi gauges under the hoods of powerstrokes and both of the gauges sprung and quit working within a week or two.

Now this last part sorta has me worried. I just fired my new motor off last night and set the liquid filled guage under the hood to 68psi. My plan was to leave the liquid filled gauge on the regulator and put the adapter in the filter housing with the electrical sender for a gauge in the cab. But I really don't want to do the " hood insulation delete mod" if this is going to be a problem. Been there and done that before!

Problem I had was the needle in the gauges sprung and the gauges quit working, there was no fuel leak, just gauge no read right.

didn't know it was mechanical. i can't see the pics.
