hi guys,

A fuel pressure gauge from Glowshift was given to me as a gift. (I know GS gauges don't seem to be that great but eh - it was a gift so why not?) It says to install the sensor to either the fuel filter housing, fuel rail, or lift pump. What would you guys recommend? At the moment I think putting it on the fuel rail would be best (but i could be wrong). Any advice would be appreciated. Here is the instructions to the pump in case someone wants to see how the sensor looks.

PS. I read somewhere that this particular model actually has 3 fuel pumps (90' xlt lariat w/dual tanks). a low pressure one in each tank and a high pressure on on the frame rail. I was never aware of this. not really sure where to look for it if its on my truck. Can anyone confirm this?

thank you everyone for your time!

You only have two pumps. One high pressure pump in each tank.
You tap into the fuel rail test point for the pressure gauge.
