Description

The Goodmark/ProEFX TNKGM25A is a fuel tank designed for 1971-1972 Buick Skylark and GS models. It is fuel injection ready and includes a two-piece neck design for easy connection with a 2" ID rubber hose. The tank features EFI-style internal baffling with an extra-large 4.8-liter dual tube baffled fuel tray to prevent fuel pump starvation. It is constructed from galvanized steel and powder coated silver.

This fuel tank is compatible with aftermarket 5-bolt senders and accepts factory (0-90 ohms) or aftermarket gauges. It is not recommended for use with TBI or high-flow fuel pumps; an alternative part number, TM34HN-T, is available for those applications. The fuel pump and sender are recessed for easy installation without requiring modifications to the car, and the tank provides an OE appearance when installed.
