Making an LH2.2 FPR work on a LH2.4 rail

[lookforjoe]

I needed to get a 93 245 running so I could test other issues - I knew the FPR was bad as it was literally pouring fuel out the vacuum port

The only 3bar regulator I had on hand was from a LH2.2 740T, so I cut the old FPR up & made an adaptor to go from the rail to the older style FPR

With that out the way, I was able to diagnose the other issues that the PO had created in his effort to compensate for the fuel dump

How did you install the fuel pressure tester and where?

I’m extremely interested in how you got this to work as I cannot find a port suitable to thread into my tester.

I'll add a pic later. It's an old Volvo tool, that goes between the rail and the fuel line with a banjo T that feeds the gauge.

Includes the male/female I/O to branch the feed line, and the nitrile line ending in the same union joint, which is where I added the generic gauge line

5116 is just the line that connects to the gauge. The actual adapter is 5265.
