Help with warm start issue - Whipple

[khsonic03]

I feel like someone should have mentioned that the boost-a-pump might not have a check valve. Which makes warm starts an issue. I had this problem on my Whipple until I got a fuel system. Chances are the issue is mechanical.

Thanks. This only applies when you replace the fuel pump. I didn't replace the pump; only used a BAP. I believe the newer DW400's have the check valve now, too.
