Fuel PSI
Going to monitor my fuel psi for a couple days of mixed driving and see if I get any fluctuations in my psi. My pump whines, but the car pulls hard and idles well, so I think the only way to tell for sure if I have a pump issue is to monitor the psi's... So... what should I see at:
Idle?
Part Throttle?
WOT?
Thanks!

Ok I monitored it through all kinds of driving...
58-59psi Idle...
Light throttle= 58
1/2 Throttle= Maybe down to 56-57
WOT= 55-56 (definately no lower than that)
There were never any random drops or fluctuations at any time or rpm...
Like I say, car runs great, no problems.. just a noisy pump... should I ride it out since the psi's all look good?

So if it was your car would you chalk up the small pump noise to just a noisy pump? Or would you change it out? I tend to be a bit of an alarmist I guess, but I'll be pissed at myself if I get stranded in a couple weeks...but I havent decided on a pump set-up yet and I dont want to throw money where I dont need it yet...

I guess it depends on the circumstances. If you don't feel comfortable, change it. While your at it, get an upgraded pump form Lonnies Performance.
