Billet Fuel Pump Hanger and High Flow 340 Stealth Pump assembly provides a high-flow, high horsepower fuel pump installation for stock 86-98 Mustang fuel tanks, eliminating both fuel starvation and return aeration common to the factory Mustang hanger.

Rated for 700 FWHP Forced Induction EFI, 850 FWHP Naturally aspirated EFI engines on gasoline.  Reduce HP ratings by 30% for E85 applications.

The new P/N 18638 Billet Mustang 340 Fuel Pump Hanger Features a CNC machined billet aluminum hat with ORB-06 outlet and return ports, allowing the use of AN-06 or AN-08 supply and return lines, making it suitable for both EFI and carbureted engines. The new Mustang 340 Fuel Pump Hanger is constructed with a stainless steel mounting bracket and features a CNC machined 6065 aluminum hat that fits the stock tank and is bright dip anodized black and laser engraved.

The Billet Mustang 340 Fuel Pump Hanger ships completely assembled and is designed as a direct fit for the OEM fuel pump opening, providing easy installation and a leak proof seal. The internal, stainless steel mounting bracket supports a preinstalled 340 Stealth Pump preset for the correct depth and connected to the hat by OEM style convoluted, submersible fuel hose for high flow and long life. The pump sets in the stock internal baffle and the return is engineered to eliminate cavitation.

Optional Walbro "Hellcat" 525 lph fuel pump available (select above).

AFM has tested the Aeromotive fuel hat with both the 340 and 525 pumps and have concluded that the Aeromotive hat is the best flowing single pump hat on the market. Adding the 525 pump will require some minor modification (instructions included) but will allow for the best results in a single pump setup. -For best results use Aeromotive HD wiring kit pn# 16307
