There may be no intank pump
Oh christ. Well the 8th digit is an F and I looked over the build sheet. LB9 MM6 G92 J65 all that jazz. He gave me what he said is the stock TPI with new injectors. He said the wiring harness is MIA though because he yanked it out when he put on the carb. I also didn't think you could get a 9 bolt with anything but TPI in 87, but I could be wrong.

1320B4U: he said it's a Holley 600cfm, but I haven't confirmed via part # yet.


This thread shows a little about the Mallory AFPR for a TBI to carb swap:

I'm sure TPI has an even higher psi pump.
