Fuel pump leak
Posted: Sun May 24, 2015 3:49 am
Hi all,
Just coming to the finishing stages of my first phase of restoration and I?ve run into a small fuel leak. My S2 elan is fitted with weber carburetors, new all metal style pump, canifure line from fuel tank to pump, and a braided stainless line connecting the fuel pump outlet to the carburetors. My leak is coming from the outlet and upon closer examination the copper pipe entering the outlet on the pump felt loose even with the nut quite snug.
Originally I installed the outlet fuel line with a small copper ferrule and after I noticed the leak and removed the line the ferrule didn?t appear compressed at all compared to images I?ve seen on this forum. I also tried to flare the copper tube hoping for a different result however the leak persisted and in a more serious state.
Honestly I have a very minimal knowledge of mechanical fuel pumps and I?m not sure how to narrow this down. Am I using the incorrect ferrule, nut, or both?? Would be interested in some of your experienced opinions.
I?ve attached some images for clarity..
Ferrule seen has been installed but doesn?t appear compressed at all to me?
Fuel line to carbs
What my fuel line & ferrule looked like immediately after uninstallation.
View inside the fuel pump & outlet.
Attempting to flare the fuel line.
