Installing a Fuel Gauge?

I want to install a fuel gauge. I don't even know where to start. I am a wana be DIY. Don't know much yet but am learning with every project. I have installed a FRx. Under the hood gauge will be fine. Need gauge recommendations, and what do I hook it too?

back of the fuel bowl lower right (from the front of the truck) is a plugged port, -4 or -5 ORB fitting, you'll need a ORB to NPT adapter then a NPT 90* and then the gauge will be in the valley but visible just over the fuel bowl

Anyone got any pics of what this looks like where it mounts.

I found 2 pics

be aware, this is only good for setting and checking idle fuel pressure, which is not the most useful, I had mine in for 2 years or so, then I got an isolated in cab fuel pressure gauge and found my pressure was dropping significantly under load.

How would I go about doing this (see in red) I am curious about my pressure under a load as well. Some times the truck just doesn't feel right when I put it under a load. Thanks.

Dont... get an electric fuel pressure gauge and be done... Once, right and safe.

Isspro, or Autometer, but I am partial to Isspro.

the isolation diaphram with gauge works great for me, I don't have to worry about a transducer failing, or a voltage problem skeuing the reading.

or if you just want to make one temporary to go under the wiper, you could do it really cheap in ipex (plumbing pvc) and then remove it after you find out what your pressure is under load, ipex is good for 300psi I believe

If I was to put a permenant gauge in the truck, Does any one make a cool single gauge pod for the truck? I already have the three gauge pod and don't want to scrap it just to go buy a four gauge pod? Thanks.
