Fuel leak
I dropped the tank on my 94 Explorer and found that the outlet coming out of the sending unit was leaking badly. I pulled the clip off the flexible fuel line but can't get the line off the outlet on the sending unit. Is there a trick to it, or am I just not pulling hard enough? Also, does anyone know the best place to buy a new sending unit? Locally they are about $110.00, pump included. I really don't need the fuel pump if they are sold separately. Thanks for the help.

If you are talking about the fuel line exiting the pump you will need a special tool to unlock the line. If it is leaking on the pump side of the connection you will have to replace the pump, these lines are known to rust and perforate

If that pump hasn't been replaced in a while, I'd replace the whole assembly... it will just be a matter of time before you end up dropping the tank again to replace a worn out fuel pump... why do all that work twice?

I'll be replacing the pump also. It seems most sending units include the pump as well. The next problem I'll be facing will be getting the tool to remove the fuel lines. I will probably have to see if any of the local auto parts stores rent them out.

When I replaced my fuel pump, I tried using the "ring" shaped plastic tools that I got at Autozone. I don't remember exactly why, but I couldn't enough behind them to get the tool to slide into the fitting. Ended up going to Napa and getting a different shaped fuel line fitting tool (kind of like double ended pliers) that worked better in that application. Neither style is very expensive, but I found the one style more effective at removing the lines at the pump.

The trick with the line release tool is to insert it as far as possible into the outer fitting then push the 2 lines towards each other, the outer one will slip over the tool and release the lock, then pull the tool and the outer fitting (together) away from the inner line. Found this to work best especially for the cheap plastic tool.

Hey don't knock the cheap plastic tools! I've used my $10 set for over 6 years now hundreds and hundreds of times for everything from A/C lines to fuel lines!
I also have the "scissors" metal tool, and have never gotten that to fit anything correctly!

I was under the impression that the purpose of this forum was to assistance those in need, but maybe that isnt so anymore.
