I want to check my fuel pressure, do I need to buy one of the expensive guages that hypertech and accel make or is there a cheaper alternative.

Casey,

You can buy an Imperial Eastman 423-CR gauge for $13.91 and a 1/4" SAE flare hose for the fitting for $9.65. You now have a precise fuel pressure gauge and hose for about twenty five bucks, brand new.

Look at catalog page 511.
