Press Release : AEM’s New E85 Mustang Fuel Pump


The creation and introduction of alternate fuel vehicles and E85 had originally been planned on lowering vehicle emissions and relieve our dependency on fossil fuels in the traditional sense. But aftermarket enthusiasts have found ways to incorporate the slower burning, higher octane E85 into their own turbocharged or forcefed application.

Coupled with a low price tag compared to higher octane racing fuels, which can often times be triple or quadruple the cost of E85 per gallon, and it’s clear to see that the E85 trend that isn’t going away anytime soon.

Enter the AEM Electronics E85 320lph in-tank fuel pump upgrade specifically designed for the 1985-1987 Ford Mustangs (Part Number 50-1205). This center inlet fuel pump comes complete with a wiring harness, pre filter, internal fuel hose and clamps, end cap and rubber buffer sleeve to go along with the compact 39mm pump.
