Excellent.   I was a  bit worried I’d have to make a side trip to Pegasus on the way to That Loooong Race tomorrow…

Question: is changing from the higher pressure Holley fuel pressure regulator (1-4 psi) to the lower pressure regulator really as simple as changing that cone-shaped spring under the cover?

Somewhere along the line, it appears that I got the wrong Holley fuel pressure regulator – the higher pressure one.  Adjusted all the way to the low end, I had 4.5-5.0 psi of fuel pressure.  For years, that was just fine with my SUs, so I just left it.

But now I have switched to a different set of SUs and they’re bleeding fuel all over the place (out of the vent hole in the bowl covers and out of the jets).  So I dug around and found that I had a spare Holley fuel pressure regulator.  And it had a different color spring (red vs. silver).  So on a hunch I switched the springs.  Voila!  2.5 psi.

Is it really that simple??
