FIQURE NO. 1 - FUEL TANK ASSEMBLY
Some late built 1986 C/K trucks may have been built with 1987 fuel tanks. The 1987 fuel tank contains a fuel baffle which can cause interference with
the fuel sender float arm and not allow the fuel gage to read below 1/4 tank of fuel. If the truck is equipped with dual fuel tanks, this condition can
occur in either tank. If this condition is encountered, the fuel tank must be replaced. The 1987 fuel tanks can be identified by removing the fuel tank and
fuel tank sender and checking for the reservoir (plastic) which is attached to the bottom of the tank by two studs which are approximately 4" from the
center of the fuel sender unit, See Figure No. 1. Refer to section 6C-Fuel System for fuel tank removal and reinstallation procedures.
