Yep. Which always made me wonder how both generations have injectors rated to flow the same.

 

[mrcooley]

maybe different size fuel lines or different pumps.

with the vacuum line off

what vacuum line? is that some nifty trick to get better pressure?

The vaccum line attached to the FPR.

yep our FPR are rising rate so they are modified by vac and boost.. in order to set the fuel pressure you have to disconnect the vac line .. set it.. then reconnect the vac line
