Removing Fuel Sending Unit
Q: Removing Fuel Sending Unit
I have a leak around where the fuel lines come out from the fuel tank. How do I remove the fuel tank sending unit? Do I need a special tool?
A: You don’t really need a special tool to remove the sending unit lock-ring. First clean off the area around the unit, (I like to use a shop vac and a brush). The ring should have 3 or 4 tabs; using a small brass drift, tap the ring around to the un-lock position. I try to use the tabs evenly so as not to distort any 1 tab. When removing the s/u, do so carefully, the filter element is usually fragile with age. Under the sending unit flange is an o-ring. Make sure this isn’t damaged and clean prior to installation. In my case I had a gauge problem and decided to repair and replace the s/u. I couldn’t find a new or rebuilt anywhere. So, disassebled it and carefully cleaned it and it has worked fine ever since.

In the Service Manual I received from the Gentlemen I purchased my ’68 350 Coupe 2bbl it states that one of the connectors (looks like upper fuel tank filler neck to the filler neck retainer?) has to be soldered as well as requiring tool J 22554 for removal/ install of the sending unit. I looked online and You Tube to see if I could find this process being done to no avail. I am not familiar at all with soldering at all so if this is not a “requirement” for proper install of the new sending unit I’d like to avoid it. As far as that part goes, I see that it is a sending unit removal tool but it seems like that can be carefully done with a couple of “taps” evenly around the tabs. Anyone done this or as a group, feel soldering and “finding” the tool is a requirement for proper install. Thanks for your feedback.

Not sure if my previous posted (don’t see it; thought it sent) so apologize if it a redundancy; The Manual shows that the installation process of a new sending unit will require solder. Just wanted to see if that was an actual need process? I am not familiar with soldering so if I can avoid it, I will. Thanks for your reply and assistance on this.
