when i installed my 5x14's i raised the idle and turned down my fuel screw (too hot) (but turning down the fuel alone will cause you to raise the idle) I think you just need to adjust your pump. do a lot of reading before you start so you are sure you know what your changing, especially when you get to that fuel screw. your not getting the full potential of those injectors yet.....then you will need to address the fuel supply.

the lope your getting is probably because your new injectors pop pressure is set for a p-pump i bet!

"We at FASS have systems for the First Gen's up to 150 GPH"
what is the advanteges to this? and does a fass system just suppy fuel to the pump with more pressure then the stock primer pump? and what do you do with the primer pump when you install a fass system?

Installing larger injectors coupled with turning up the fuel (IP) can result is the IP demanding more fuel than the lift-pump is capable of supplying.
Increasing the fuel pressure available to the IP will not correct a starving IP. Increasing the volume of fuel available to the IP is what is needed.
While fuel pumps like the FASS are very capable of meeting the demands of larger injectors / turned up IP, the less expensive low pressure piston lift-pump if not the 12v 2nd gen high pressure piston lift-pump (with a pressure regulator) will satisfy the demands of the typically bombed VE fueled 1st gen just fine.

I ran the same set up on my 89, that walbro 392 pump is awesome!

where does your 1/2in return line go to on the tank? cuz i know on my tank the old return fitting on top of the sending unit isnt 1/2in.
