A & E Hand Tools’ Star Products brand has introduced their GM T.B.I thru Filter Adapter Set with Manifold (part no. TU-26). This adapter set contains all adapters necessary (including the manifold) to cover GM T.B.I. cars for testing fuel pressure at the filter. With this set, the technician removes the fuel filter near the gas tank. Selecting the same adapters as the fuel filter, the adapters can then be screwed onto the manifold by hand. The manifold is then connected to the fuel lines in place of the fuel filter. The TU-26 is a great time-saver when comparing old style testing under the hood.
