What comes in the B-Body line kits

Fuel kits run tank to rail in PTFE lined, black covered stainless braid with clamps and screw together rail fittings.
On 6601-00 a single OE style filter and regulator holds 58 psi, the GM LS spec.
On 6605-00 you get a separate filter and an adjustable regulator with a vacuum and boost port.
The 6L80E-10L90E cooler kit adds a billet manifold that bolts to the transmission.

1991-1996 B-Body line fitment notes

The 255 LPH Walbro pump kit pairs with the 255 LPH line kit, 6601-00.
Per the guide, a 4L60E or 4L80E fits the B-Body tunnel as is, so either matching cooler kit is a direct pick.
A 6L80E or 6L90E needs tunnel work at the tail shaft housing before the cooler kit goes on.
Both fuel line kits are for returnless rails only.

1991-1996 Impala SS LS hose and line FAQ

Do I need a new tank to run an LS in a 1996 Impala SS?

Not with BRP parts. Its pump kits for the 91-96 Impala drop a new pump onto your existing sending unit, with fittings for a BRP fuel line kit.

Which cooler line kit for a 4L80E in a Caprice?

The 4L80E kit, which also covers the 4L85E. The guide says the 4L80E fits the B-Body tunnel without changes.

Which fuel line kit goes with the 340 LPH B-Body pump kit?

BRP does not say. Its line kits are labeled 255 LPH and 400 LPH, and neither one names the Aeromotive 340 LPH pump.

Will the steering hose kit reach my B-Body steering box?

It runs from the new style LS pump to early and late style boxes. BRP does not name the B-Body box, so check yours.
