Does anyone know why my REM shows 0.0 volts with the key on engine off, but 14.0 volts when the engine is running?
Edit: With the engine off my battery measures 12.7 volts with a digital multimeter.
No the XJ axle perches are not the same distance apart as the MJ ones. They will need to be cut off and rewelded.
Here is a good diagram of the difference.
The piece going through the o-rings and clip is just an installation tool. Which makes it harder to install the clip. The o-rings and spacer go inside the fuel pressure regulator and the clip goes on the fuel line. They are not meant to be installed together.
I had the same leak last year and the only parts I could find to fit the Renix fuel rail are from Crown automotive. The part number is 83502745. The cheapest place to buy them is from Quadratec. You might as well replace the o-rings on both the feed and return side at the same time so order 2. (They are the same on the Renix fuel rail)

There are 2 o-rings per fitting with a spacer in-between them. Make sure both old o-rings are removed when installing the new ones.
I agree with the above roll the window all the way down remove the lower exterior window trim, just slide it up to remove it. Then with a hook made out of a stiff wire fish around in the door and hopefully pull the latch mechanism to open the door.
Ultimately I would like to put a XJ44 under it but that will wait until I find one at a good price. If the 35 breaks I will might swap to a Chrysler 8.25 as they are easier to get quickly.
