Fuel Problem

WallyGatorFL · 07-16-2001, 02:30 PM

I've got a problem with fuel pressure. I have 24# injectors in my mustang and a 155 lph in-tank fuel pump. The car runs fine around town but when I run it at the drag strip I keep running out of fuel! I keep running a 15.04 at 75 mph! This is really discouraging... If anyone has an an idea of what to do please let me know.
thanks
Walt

If you don't have an adjustable fuel pressure regulator you will need one. Set the pressure to around 38-42lbs with the vacuum line off. If you already have one, what kind of pressure are you running now? Do you have a fuel pressure gauge that you can see while at full throttle? What happens to your pressure as you excellerate?

When was the last time you changed the fuel filter?

Just some thoughts as I read through your post. Need a little more information though.
