Hi there,
Today I finally got around to installing my fuel pump check valve. The good news is I didn't have any leaks from the valve, but I noticed my engine started idle hunting after the install, (and after it warmed up). This is new. What are your thoughts?
- I have DMC's new pump (love it by the way), but it didn't have the external check valve as it was installed before they discovered that it needed one. So now I have one.
- my engine is totally refreshed, with many new parts, including new small vacuum lines
- my CO screw has the permanent plug, so it hasn't been adjusted
As I said, the engine had a smooth idle (as of yesterday) before I installed the check valve, and that was the only part that was added today. Do you think the fuel pressure was impacted slightly by the valve to cause this?
Thanks,
Dana
