Good point, and I should've mentioned that I dis-connected the return line and ran it into a catch can, then started the car and re-checked the pressure gauge while running. There was no difference, still running at 60 plus & the engine died as soon as I tried to open the throttle. The car-part site only has an used regulator pulled at a wrecking yard. I'll wait until I completely ruin the one I have, then give them a try. At the moment I have the bottom section of my regulator cut off, which is where the spring is. The valve and diaphram are still crimped into place in the upper section. I only cut the first layer of steel around the edge. I'm halfway done building a three piece clamp to put the bottom back on. I just need to make a few more cuts on the lathe, then drill & tap a bunch of 10/32 holes for a set of stainless cap-screws. Then I can test the original spring to see if cleaning it makes it work. If not, then I'll cut the spring slightly and re-test. The way I'm building the clamp, I'll be able to change the spring out with the entire assembly bolted to the engine. Hopefully the diaphram doesn't get a hole in it from all the funny goings-on!

Some of this is new to me, I just got an '84 turbo 2-door coupe with issues. I never had a computer in a Subaru before, so the test connectors & LED stuff is looming large in the near future! By the way, I'm dealing with too much fuel pressure. 60 when my book says max of 30. The engine starts but dies as soon as I touch the gas. None of the parts stores I tried have this regulator (westbay/napa, c.r.a.p.). I called a dealer in Gorst and they don't have that anymore. So it looks like I'm stuck with rebuilding the one I have. Either that or adapt some kind of aftermarket regulator. I hope there aren't too many more 'unavailable' parts like this on the car!

No worries, I've subscribed to this thread so anytime it gets anywhere I'll hear it. I'm just inspired by the possibility of cutting & welding what ever I want to put together. I'm thinking of putting a modified TH200 behind an EG33. It sure would be nice to see those pieces welded together....
