28260, Fuel Pressure
Posted by EclipseZero99, Jul-23-02 03:59 AM
What can I do to raise fuel pressure ???
cant use a piggyback regulator (because my regulator is connected to the fuel filter) and cant use a stand alone regulator (because no fuel return line) Can anyone tell me what I might can do ????

First off, why do you want to raise it?

Without knowing that, all I can say is the following:

For non-turbo: You'll have to replace your stock regulator with another unit that will allow you to adjust your base Fuel pressure. You might not have to, but it's the easiest way.

For turbo: If you want your pressure gain per boost to be higher, you'll need to put in a riser such as the vortech fmu. The ratio will have to be determined by the size of the turbo among many other factors.

OK, then you can ignore the turbo part...but still the question -> why do you want to raise fuel pressure???

I agree, why do you want to raise it?? Our cars run super rich from the factory. Raising it will cause you to run even more rich, which causes you to loose even more power.

Most people don't realize they run rich from the factory, mainly at WOT.
