G'day

As i'm going to be doing my megasquirt conversion soon i'm just wondering how i can check my fuel line joins.

Can i hook it all up, the lines, the pumps, the fuel rail and regulator and then run the 2 pumps without the computer to see if anything leaks?
I should just be able to cycle the fuel through the lines, pumps and the 2 tanks that i will have?

Cheers
