So I am putting my 78 B back together after a long drawn out rebuild. 
Finally  put the dash back in and all the connections... what's left? go buy 
a battery... just for giggles, I put a voltmeter on my old battery 11.97V... 
hum.. a little weak, (it's been sitting 3 years) but hasn't lost a cell. 

Turn the key... no click, click click.... take the cover off, hit the points 
with sandpaper... no click, click, click.

Check the voltage to the pump at the terminal in the boot. got voltage.

Take the fuel pump out connect to battery charger... clickity, clickity, 
clickety... must be bad ground.

Put fuel pump back in place. Connect battery, manually shove fuel pump 
ground into neg. post of battery... clickity, clickity, clickety... 
alright... turn the key... it started in 3 spins after been sitting 3 
years...  turn backwards from the drivers seat and look through the battery 
box at the fuel pump and happen to see a drip of fuel. shut it down. 
Disconnect the batter neg. post.

OK... so I want to see which hose is leaking... for some reason, I held the 
ground lead from the fuel pump to the neg terminal of the battery with the 
normal battery ground strap disconnected... the result was as if I turned 
the key to the on position, the interier lights came on and so did the dash 
dummy lights.. and the fuel pump started clicking... so... I put the neg 
battery cable back on the neg battery terminal and held the fuel pump common 
to the battery... nothing... so it appears the electricals act normal when 
the ground lead is connected to the battery, but with just the fuel pump 
ground to the battery, for some reason the whole ingnition systems seems to 
turn on?
