Leaky Fuel Lines

[ed armstrong]

Regarding high pressure fuel hose, I have also used it
to make a "patch fix"  on a 90q where the rubber hose
connection between the fuel filter exit and steel fuel
lines to engine was leaking. This OEM rubber piece was
crimped onto the steel lines and fuel filter fitting.
I used special "fuel injection" hose clamps to secure
the new hose. These clamps are more sturdy than normal
hose clamps in that you turn a solid bolt to tighten
vs a screw.  The hose I used was rated at a working
pressure of 100 psi and burst pressure of 1000 psi.
Haven't run the car yet but I expect no problems.
