I think those two pipes are a breather and a drain, both from the fuel cap.
re. pump and tap....
1) with a manual tap, could the diaphragm pump be damaged if you start up without remembering to switch the fuel on...?
2) Some monsters had an internal electric fuel pump (not the round one in the base of plastic tanks, but one fitted through the filler neck and secured with clips inside). See Dukedesmo's project thread for details.
