Leaky Fuel Lines

[Livolsi, Stephane]

Hi Syl.  I do have a BTDT for you as I replaced the fuel lines from front to
back in my 86 5KTQ.  I used generic off the shelf brake lines and bent them
myself where possible.  I found it easier to buy 2 short ones for going from
the engine compartment down the firewall and terminating therewith a
coupling.  Then I got long brake lines to go from that coupling back to the
gas tank/accumulator.  At the accumulator end, I just cut off the flared end
of the brake line and used a short piece of rubber fuel injection hose and
double hose clamped at each end to connect it to the fuel line I cut off of
the fuel accumulator.  I could not undo the coupling from the fuel
accumulator as it was too corroded.  One of these days, in the summer, I
will redo that end of it, possibly with a new accumulator and proper
fittings.

IMPORTANT NOTE:  I spoke to mechanics and knowledgeable people about putting
in the rubber fuel line and all agreed it was ok as long as you use
specially made HIGH PRESSURE FUEL INJECTION hose, and not the normal run of
the mill fuel hose used for low pressure applications.  I think it has been
well over a year now since I did mine and no problems at all.

Good luck

Stephane
