I have all the fittings now, but i can't seem to kill the fuel pump. I have taken out the F/P injector2 fuse (makes it look like it has a wild cam!) and have taken out what i think the the FP relay (the pump doesn't prime) But the car still runs!!! I have let it idle for a few min, but i thought that it died almost instantly. Am i not waiting long enough or do i need to diconnect something else?!

 

The oil pressure switch is the backup, so that is why it still runs. Unplug the connector above your rear axle, leading into the fuel tank. That will kill your car.

Oh yeah! I remember that being said now... well, i got it on anyway. How bad is it to keep the gauge on all the time? If it is bad, are there any quick disconnect fittings i can use?

 

As long as it doesn't interfere with anything, you can keep the gauge on there all the time if you want.
