Subject: Re: Darg Racing - Not pulling at top of gear
Regarding fuel pressure gauges, don't trust them too much. I have had about 4 or 5 of them and found that the liquid filled apparently heat up and give a faulty reading. I have one to each carb at the regulator and the liquid filled will say I have little to no fuel pressure while the standard gauge will say anywhere from 5 to 6. I found that they appear OK to set the pressure when the engine is cold but after that it's pretty much guess work. I do not re-adjust later.Rich Kinsley '64 Dodge Polara LeRoar 4dr 324 poly w/goodies--

hi don,
from your description, it sounds like a fuel problem. some questions:
- on the dyno, was your motor still making power at 6300 rpm? or was
the HP dropping off precipitously? did you have the electric fuel
pump on during the dyno?
- where did you put your electric fuel pump? should be as close to
the tank as possible as it is easier to push fuel then pull fuel.
- did you remove your mech fuel pump? if removed, what regulator are you using?
- does your e-fuel pump require a return flow back to the tank?
- do you have enough amps to run the e-fuel pump?
a fuel pressure gauge is critical to understand where you stand.
