Ok, not what I was wanting to hear but it does make some sense. Next Q

1. How hard is it to change the Intake gaskets? I've never pulled anything off of an EFI engine. Older carb'd v8's no problem.

2. The check valve, is that part of the fuel pump located in the tank or is it somewhere more accessible....

I've got the manuals, but would like to hear from someone who's BTDT!
