T&T: 120 Lehman lift pump

[bob england]

These pumps suck (pun intended). You will need to pump that little handle a 
long time to get the system primed. I suggest installing a Walbro marine 
flow through pump in line, makes filter changes a breeze, and no more hand 
pumping to prime. Plus, if your fuel pump on the main goes TU, you gotta 
backup, double plus, you can add a valve and polish your fuel at the dock.
