Aeromotive Stealth Fuel System Upgrade

Aeromotive provides a new gasket to seal the fuel-level sending unit.

You must transfer the sensor from the stock tank to the new one.

A new block-plate is required to cover the hole where the factory fuel pump assembly is bolted in. It, too, is included in the system.

The tank is hoisted up and strapped into place. Don't forget to reattach the vent tube!

We used 90-degree fittings coming out of the pump and for the return back into the tank. Generally, you want to have as few bends in the system, but we felt it was easier to run the lines with the two 90-degree fittings. Unfortunately, we didn't have the proper fitting for the return line and had to steal a -6 fitting off the wall at DMC's speed shop. The blue fitting is annoying, so we called Aeromotive and ordered a black one.

Upton mounted the filter behind the bumper...

...where it is easily accessible for maintenance.

Thankfully our '89 notchback is wired for an aftermarket fuel pump, saving us time. There is a relay in the trunk, and two wires were run through the floor and to the pump.

The wires are simply attached to the exposed posts. Don't forget to add a grommet to the hole; it will prevent damage to the wires.

The system might be nicknamed the Stealth, but visually, it's quite noticeable.

The name comes into play thanks to its quiet operation.

The pump is barely noticeable with the engine fired up, unlike other pumps that sound like a Boeing 747 jumbo jet spooling up its turbine engines.
