Ford Mustang 3.8 V6 Walbro 255 LPH Fuel Pump 1994-1997

This pump will fit every model, type or style for every vehicle listed and can flow anywhere from 0-115 psi, which is determined by your fuel pressure regulator. This is an aftermarket performance fuel pump and some small modifications may be needed. If you receive the pump and have read the included directions, but still have questions, please email us for install help. All of our pumps are always in stock and will often ship the day of payment.

Remember, having too big of a pump is not a problem, but in some applications with an OEM stock regulator you may need to upgrade the regulator to avoid issues with too much flow for the OEM components. Return style fuel systems, such as all the vehicles these pumps work with, have any extra fuel returned to the fuel tank through the return fuel line. Because of this, as large a pump as the stock lines can support is fine, even with a stock engine!

Boosted applications that see higher fuel pressures can still make 500 hp with this pump, but not when over 90 psi because the fuel heats up and can cause problems. Also, a fuel pump can't pump when it doesn't get enough voltage. If you are running high horsepower in the 450+ range you should upgrade your wiring and relay to support your new high flow fuel pump properly or your fuel pump may suffer low flow rates due to low voltage if your stock wiring is too thin and relay too weak.
