Yeah, do a quick search for glowshift and let the horror stories commence.

There's a fuel line connecting the filter housing and injection pump. IIRC (at least, the one I have) is bigger than 1/8" NPT and has to replace the banjo fitting where that line goes into the injection pump, as it's too big to go in the filter housing side. Then you can screw whatever 1/8" sensor accessories you have (or the sensor itself) into that. The more you have between the sensor and the snubber the smoother your readings will be at the gauge.

Marshall Gauge 0 60 PSI Fuel Pressure Oil Pressure White 1 5" Diameter Liquid | eBay. This is the gauge I went with. It was almost perfect size to fit in the CIG lighter hole with a little motivation. I drilled a hole in the banjo bolt for the supply line to the pump. Drill from the inside out and tap from the outside in with 1/8npt. Works great took maybe an hour for the install

Just remember if you drill it to clean it good before reinstalling. This is after all your filters and should be only clean fuel here. That is a needle valve there just in case something went wrong and you got a leak you can shut it off and still be in businesses no matter what or where u are

Here is mine.

You just beat me.
I had to do some digging. It has been a while.
Hope it helps.
DD:rocking:

I ran into a rather large problem i tried placing my banjo bolt where coors_man_2005 had his in the pictures and the bolt that i removed was larger then the 12mm banjo bolt. I did not find where diesel duo placed his. is that a different size then where i first attempted to put it?
