OK, I finally got around to fixing the sometimes small fuel leak in my
93
EV. The clamps and fuel line were cheaper then a fire extingisher
anyway.
Not sure where that logic goes. I may of found a reason for the
leaking!
Many have said that the blue return line is the one that leaks more. But
this does not make sence since the return pressure is much lower the
the supply pressure. And my blue return line was the one that was
sometimes leaking.
I started with the blue return line. It came off with an easy pull on
the crimped end. The other end with a spring clamp came off just as
easy, only after I removed the clamp! No big deal replacing it, cut a
new section of
7x3 mm fuel injection line the same length as the old one. Used high
quality fuel injection clamps. And the fuel line I used was the exact
same as the factory stuff! The same marking ID numbers.
Now the other line. This is the black supply line. I could not make it
come loose on the crimped end! Instead of risking damage to the plastic
tubing I used a hacksaw to cut a slit in the metal crimp. Now with the
old line off I saw from the markings and size that this supply line
was 7.5 x 3 mm! Same inside diameter but 1/2mm larger in out side
diameter then the return line! I replaced it same as the return.
But here is the question: Is the metal crimp part the same on both the
blue return and the black supply line? I can not say as I damaged the
old supply crimp in the replacment precess. Can anyone with original
lines go out and measure the metal crimps?
If this is the case and they are the same then we have the smoking gun
as to why a few of our EV's have burst into flames. And VW will have
hell to pay to explain this one away!
