What comes in the truck line kits

The fuel kits pair Teflon lined braided hose with clamps and every fitting needed from tank to rail.
With 6601-00 the regulator is a fixed 58 psi filter combo. With 6605-00 it adjusts and takes a boost reference.
Cooler kits are black covered stainless braided high pressure hose, cut to run from transmission to radiator.
The steering kit joins the LS pump to early or late style boxes.

1964-1972 truck line fitment notes

BRP truck tanks mount under the rear frame rails behind the axle, and mounting needs drilling.
The 255 LPH truck tanks are rated to 550 hp and the 400 LPH versions to 750 hp.
For the factory gauge, 1963-1966 tanks carry a 0-30 ohm sender and 1967-1972 tanks a 0-90 ohm sender.
The guide says most late model transmissions fit the factory tunnel without floor changes: 4L60E, 4L80E, 6L80E, 6L90E, 8L90E and six speed manuals.

1964-1972 C10 LS hose and line FAQ

Which line kit goes with a 1967-1972 truck tank with the 400 LPH pump?

6605-00. BRP built it for its 400 LPH tanks, with an adjustable regulator and a separate filter.

Which cooler kit fits an 8L90E in a 1964-1972 truck?

000-6630-89. It covers the 6L80E, 6L90E, 8L90E and 10L90E and includes a billet transmission manifold.

Does a bed fill or side fill tank change the line kit?

BRP does not list separate line kits by filler location. The choice follows the pump: 6601-00 for 255 LPH, 6605-00 for 400 LPH.

Will a 4L80E clear the tunnel in these trucks?

The guide lists the 4L80E among transmissions that fit without floor changes in most cases. Its cooler kit is 000-6630-80.
