The fuel pressure for a 2003 Ford Mustang GT can vary depending on the specific conditions. According to the search results, the fuel pressure on the return style system is always the same and doesn’t fluctuate between numbers. The flow of the injectors is rated at 3 bar or 43.5 PSI by Bosch and Ford. With the vacuum hose attached at idle, the fuel pressure ranges from 35 to 50 PSI, and with the vacuum hose detached, it ranges from 45 to 55 PSI.
Please note that these values are based on the information provided in the search results. It’s always a good idea to consult the vehicle’s manual or reach out to a certified mechanic for the most accurate and up-to-date information.

What PSI pressure for Mustang GT?
32 PSI
If you are installing a set of aftermarket wheels and tires on your Mustang, 32 PSI is a good average to set your tire’s pressure to. This chart is a guide to help you get your tires inflated to the correct PSI. While we strive for 100% accuracy, your specific car might be different.
What is poor fuel pressure?
Generally speaking, low fuel pressure means you don’t have enough fuel getting to the engine, and/or you have too much air coming in. The fuel-to-air intake ratio is thrown off and it will cause engine performance issues. You may have trouble getting the car started at all when the fuel pressure is too low.
What is the fuel pressure for a 2004 Mustang v6?
Normal fuel pressure on your 2004 3.9 needs to be 35 to 70 PSI , anything less would mean the fuel pump or the driver module is failing and needs to be replaced.
What is the normal psi for fuel pressure?
30 to 50 PSI
This range can vary depending on the make and model of the vehicles, but for most gasoline cars, fuel pressure falls within the range of 30 to 50 PSI.
What is too high fuel pressure?
It really depends on the type of fuel system the engine has. If it is carbureted, anything more than 6 to 8 psi will cause fuel to be forced past the needle valve in the float assembly, and soon it will be flooding the engine through the vent tube. If it is on a fuel injection system, results will vary.
What PSI level is too low?
Tire pressure between 32 to 35 PSI is most suitable for most vehicles. However, one can go as low as 20 PSI (although that is not recommended). Anything below 20 PSI is considered a flat tire. PSI stands for Pounds per Square Inch.
What is too much fuel pressure?
It really depends on the type of fuel system the engine has. If it is carbureted, anything more than 6 to 8 psi will cause fuel to be forced past the needle valve in the float assembly, and soon it will be flooding the engine through the vent tube. If it is on a fuel injection system, results will vary.
What should the fuel rail pressure be?
No matter what operating condition (short of demanding more fuel than the pump can supply), pressure in the rail will always be 58psi (or pretty close). When idling at 20 inHg, this means effective pressure will rise to 68psi because the vacuum in the manifold is adding 10psi to the rails 58psi.
What PSI is too high?
But you shouldn’t go too much over recommended PSI. You can safely over-inflate tires by up to 10%. For example, if your tires have a recommended PSI of 35, you can go up to around 38 PSI without worry. Anything more than that is too much and not recommended.
How much fuel pressure should a 2002 Mustang GT have?
| Year | Engine Displacement Liters | Fuel Pump (psi)- |
|---|---|---|
| 2002 | 3.8 | 28-54 |
| 4.6 | 35-45 | |
| 4.6 | 35-45 |
