Fuel pressure issue

[kyleh20]

I recently installed a a fuel pressure gauge in my truck from glow shift. i know this company might not make the best products. but the issue is my fuel pressure is reading about 80 psi that seems really high and i don't know what i should do. do i need a regulated return? of riffraff makes the fuel line cross over. is this normal? i thought it was only supposed to be about 60 - 70 psi. any information would be helpful.

thanks kyle

I just today installed the Autometer gauge and my was 64. While driving it was between 60-64. It is the Autometer Rousch edition that I bought off of eBay. I put the fitting at the fuel bowl.

I too was curious as to what the pressure should be.

After installation and startup, I looked at the frame rail under the driver's side and took a picture of the pump. I assume that this is the stock electric fuel pump?

Yea 60-70 is usually preferred. Maybe your FPR is clogged up? Dirty FF? Clogged return line? Hard to tell
A RR, fuel cross over, etc. is not going to lower your fuel pressure. It allows fuel to flow THROUGH the fuel rail, THEN to a FPR which allows for more consistent pressures as well as to let any air pass through. It allows for adjustable fuel pressures but you've got another issue I think.

Yes, that is the OEM pump. There is only one, right there under the driver's seat.

well i have a new fuel filter and how would i check if the FPR is clogged or the return line is clogged? i am the second owner but they did not say there was any work done to the fuel system

You could look in the fuel bowl and see how dirty it is in there. The FPR is bolted onto the side of the bowl. Maybe the FPR went bad. The return line isn't something you can see in. You could undo it and maybe blow air through it.
