I changed it tonight.
It's my only car, down to only the 740 wagon. It's the 8 valve and has the square ignition coil, so Regina.
The only fuel pressure regulator I could find in town was for the Bosch, it was "only" $60. The cheapest Regina I could find was $100.
It needed to be replaced as it was leaking more each day and I REALLY don't need an engine fire in my only car...while my wife is driving...my kids.
So anyways, replaced it tonight, wasn't too bad and didn't take too long. Took it for a spin, seems good.
Glad to hear that the computer will alter things to keep it from fouling the plugs and such.
Thanks so much! This forum and people such as swiftjustice44 especially have been a great help on my 740 turbo, 740 wagon and 850.
