I purchased this a while back but never got around to installing... It is the BBK Fuel Regulator.. The part/model number is 1714.. As per Summit Racing it will work with the following vehicles:

1985 - 1992 Chevrolet Camaro 5.0 TPI
1987 - 1992 Chevrolet Camaro 5.7 TPI
1985 - 1991 Chevrolet Corvette 5.7 TPI
1985 - 1992 Pontiac Firebird 5.0 TPI
1987 - 1992 Pontiac Firebird 5.7 TPI

I am asking 60 shipped ... Item is brand new.. Ordered it from summit racing but never got around to having it installed.. Recently sold my Iroc so no longer need it...
