This has been a good post. I purchased a turn key late model with a Wissota engine on methanol. It had 2 return lines, the one off the pump with the .160 pill and one off the log with regulator which I found odd. Looked at KSE website and eliminated the the regulator. Well when I fired the engine it looked like a top fuel dragster it was running so rich. I installed the second line with regulator and it ran perfect. Still would like to run only one return line. If I run off just the regulator and eliminate the KSE pump return line will that do the trick? Is the KSE regulator a good piece. I see it uses Holley jets which you can change to set idle fuel pressure.
Also wanted to add that my idle pressure was 3 psi. so I was surprised at how rich it was running. It must be a volume issue and not returning enough to the cell.
