Those of you with Fuel Pressure Gauges. I just got my Autometer 4363 Fuel Pressure gauge. My question to you guys is about the sending unit. The one they sent me has a schrader valve on the end of it. The only Schrader vavle I know of is on the end of the drivers side fuel rail. Aside from the fact that they are the same gender connection(ie male to male) the instructions specificially say not to mount the sender on the fuel rail.
So how do you guys have yor sending units mounted?
Thanks guys,
Mike

Re: Those of you with Fuel Pressure Gauges. I used a connection in between to solve the male/male problem, make sure you use some teflon though to make sure it seals all the way... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Re: Those of you with Fuel Pressure Gauges. if it has a valve in it then its not gonna read fuel pressure unless the valve is pushed in or removed completely.. i have never seen one of these with a valve in it
you of course do have to remove the valve from your rail as well.

Re: Those of you with Fuel Pressure Gauges. Hey Guys,
I guess I'm getting a little confused here. Which port are you guys tapping into to get fuel pressure? ie where specifically are you attaching your sender unit? On the fuel lines there is a port with a green cap which is labels evap port or something to that effect. There's the port on the drivers side fuel rail. It looks like a tire valve. Am I supposed to rip that valve out???
The sender unit I was sent looks sort of like a schrader valve on the one end. The threading on the outside is identical. But on the inside it is solid and has a small hole in the middle for the fuel to travel. No valve setup like what is found on the fuel rail schrader valve.
I'd like to find a way not to clutter up my engine even more if that's possible. But beggers can't be choosers <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Those of you with Fuel Pressure Gauges. I use the tire looking valve on the fuel rail. Take the center out of it and get a adapter and put it on there. I had to really tighten mine down to get it to seal right.
