just changed to Weber carb on my 87 Samurai. l can not figure out where one of the the hoses from the fuel pump goes. (1) is from tank (2) is return to tank (3) to carb (4) is to canister (5) lowest part of fuel pump, no idera where it goes... Can anyone help. l may have ruined my fuel pump by hooking it to a vacumn hose. Engine smoked out tail pipe for 20 minutes and 5 more after l diconected it. Now seems to leak oil from that hose.

There are vacuum diagrams available at most auto parts stores and in Emission control manuals. Do not guess, you can cause irreparable damage to the emissions system and could cause a fire by guessing which hose goes where.
