Surplus tank and sending unit
First, this site is the best..It has answered almost all of my questions and the people are great. I have purchased the surplus tank and am in the process of getting all the parts to install it in my 72 lwb. I have searched and searched and almost got all the info I need. I still have questions about the sending unit and how it is going to be hooked up..I have only found one part number on the site for a sending unit for the surplus tank and it is FG05f..which this is a 3 outlet type.
question is: what do you hook up all the outlets to? I do have the charcoal canister up front, I know one goes the there, one is the fuel line, and the other I think could be used for filler neck vent?? is this right? Also I have seen sending units that are drivers side or passenger side w/eec and wo/eec, what are the diffs? The filler neck is going to go on the drivers side so to me that means I need the drivers side sending unit? Also on my stock tank I have two outlets, what is the second one for? and it the one on the passenger side the tank vent to the cannister? I have pics of my tank and the new sending unit ![]() ![]() ![]() ![]() any other tips or suggestions for a sending unit that will work is greatly appreciated. |

Re: Surplus tank and sending unit
The smaller connection may be for the fuel return line. Unless your engine has already been equipped with that emissions feature, you shouldn't need it. I'd pull my pump assembly out and match the connections to the new one, based on the old one. I'd simply cap the unused port.
Okay, I re-read your post and I don't know squat. If you have the canister, then I don't have a clue. So, you still have questions and I don't have answers. Sorry.

Re: Surplus tank and sending unit
I am going to say that is a return line that comes from the pump. What does the floor look like what the line come through is there 2 or three holes? another picture might help.

Re: Surplus tank and sending unit
I have a question for you. Were you able to use the old send unit or did you have to purchase a "repo" unit? If you purchased a new "repo" unit where did you get it. I have a similar question posted regarding my problems with a send unit from LMC that has failed twice. Looking for another source. Thanks.
