A lot of time was spent carefully installing the fuel pressure regulator.
Here it is on the right side of the passenger (PAX) area. I had a lot of trouble getting it fitted in this tight space with the pressure sensor and the MAP connection. It has a nifty bracket that you can’t see and two clickbonds holding it in place. The braided hose was challenging too.
FGast forward to NOW. We fired up the fuel system to set the 35psi pressure with this regulator.
That didn’t work because I’d set it up the wrong way around all those years ago. RTFM? I didn’t read it carefully enough. This is how it should have been, the bottom outlet is the one that goes to the tank, the side inlet is from the engine.
Here you can see I have begun to cut some metal to make a new bracket and remount this thing.
Finally I have the new bracket made after a couple of days fiddling. The sensor also ended up needed two fittings to get it to sit in the right place. The main bracket was fabricated to use the old position clickbonds as I didn’t want to do that bit again as well.
Here it all is back in place like nothing happened. I did get it reset to the required 35psi after some work and all was well with the world. That lasted until, the next day.
The pressure was low for some reason. I could only get 10-15 psi. What was going on… some time later I discovered the problem. To get fuel pressure, you need….fuel. Yep the sump was a little low. The jokes are on me. I put in 10 liters and all was right with the world again.
Oh, see that new black pipe that was silver before? Yes with the new position of the regulator I needed a slightly longer hose. I made it and pressure tested it to 1000psi. It leaked, a tiny bit, I eventually fixed it. I hate leaks.
Here is that regulator, well hidden and forgotten. Now I had the pressure set correctly, the standby pump cutting in at around 25psi and we can move on towards engine start after this very long two day delay.
