I installed a new walbro fuel pump a few days ago. I want to test the system before i put the rear end and exhaust back in. I have the intake manifold on an the fuel system all hooked up. None of the other sensors are plugged in tho, as its still being re-assembled from my cam swap. Can i just put the battery in and turn the key to on to see if it pressurizes. or could this cause problems with nothing else being hooked up.

 

As long as the fuel system is closed, there should be no problem pressurizing it.

 

Thats what i figured, i just want to make sure the pump works, and there are no leaks in the system.
