Ok that's something I could think about doing too. Because I need to figure out another place to put it. I could run a hose from that tap to the front of the truck and put my sensor. Somewhere more accessable as well 

I have one of these in the 1/2 inch fuel line under the hood with the snubber screwed into it and the fuel pressure sensor screwed into the snubber.

Yeah...

That's the problem you need distance from your last snubber to allow the remaining pulses to fade out.

Always have your sensor or tap for a mechanical gauge after your last filter also

So it would be on the fuel line leading up to the injection pump?

This is mine for a mechanical pump. It has been like this for 8 years. I still use my factory filter.  I cannot see any harm in the gauge tap being at the pump with no filters after the tap for the gauge. This is between the factory filter and VP.

Be aware... Now with mechanical gauges typically there is 5 to 7 feet of tubing between the tap point and the gauge. Now with electric gauges you need the same amount of tubing distance as well. A lot of people just screw the sensor directly into the tap point. This is wrong. You need to have that 5 to 7 feet of tubing yet this what allows the pulses to fade into the distances of the tubing. Still need a snubber too..

I have the snubber on the sensor right now but I bought the fittings to put hose from the tap on the pump all the way up to the engine bay to put my sensor at the engine. So should I still keep the snubber at the sensor or put it at the tap for the pump?

Tap point -> Needle valve -> Snubber -> 5 to 7 feet of tubing -> Fuel pressure sensor.
