I did a few searches and came up with no pictures just a few guys recommending that the gauge is going to be 1/8" NPT and that they would need to tap the fuel rail. I just want to make sure I do the install correctly since it will be a mechanical gauge I can either tap or get an adapter from what I read.

If anyone has any pictures of how it is installed on a 2.2L I would be very greatful. I just want to have this to troubleshoot any type of fuel problems and be able to monitor how the fuel pump is acting since I have changed it out twice.

Thanks in advance for any help anyone can be.

Here is what I did on a 92-97 style LIM-


You could also tap the boss on the top of the "rail".

.

I tapped the end of the fuel rail (see the closest end of the runner/fuel rail assembly in James' picture above) and used a 90* elbow. It has been working great for four plus years. It fits nicely between the power steering pump and the valve cover, next to the P.C.V. valve.

I removed the motor mount and used a 90* drill adaptor to get to the end of the fuel rail and a colet to tap the threads. Be sure to relive all the pressure from the fuel rail, remove the fuel line and use rags and q-tips to soak up all the fuel out of the fuel line. I kept the nozzle of a shop vac next to the rail while drilling and tapping to suck up all the shavings. Afterward I blew out the fuel rail, to make sure there were no shavings left in the rail.

I have a 98 2200, and I TIG welded a nipple onto the fuel rail, right in the middle.

does your 2.2 have a schrader valve on the fuel rail.my s-tyruck does and that's where i mounted it.it's 1999 don't know if that makes a diff.

The pre-'98 has one also, but it's at the opposite-end of the head. I figure if you were to remove the core with a tool from the tire-repair section of Auto-Zone, and then install the gauge with a 90*-elbow of 1/4"-NPT... that'll work for you with allot less trouble. That is, if you don't mind having to rely on pulling the fuel-pump connection & running the engine until it dies & won't start to purge the system of pressure after such an install.


Go beyond the "bolt-on".

It's a 95, I'll look around I was hoping for a method where I would not have to tap into the fuel rail. I don't have much experience with engine work so I would rather take the easiest route. The last suggestion seems the easiest but I am not sure how to do the rest of the things that nickelin dimer is mentioning.

Thanks for the help so far. I'll have to look at some of these pictures closer when I am ready to install.

You could "T" into the fuel feed line by the firewall, before it goe to a hard line.
