It's true that a flexible line can cause an oscillation in pressure in the six injector lines where pressure is used to control flow and which varies by very fine amounts. However it is safe to replace all the others with standard rubber hose as long as it'll take 5 bar pressure.
My hose set is made from a semi-rigid thermoplastic, except for the one in question which is low pressure and I use standard fuel hose and an o clip for ease of install.
Best Wishes,
Martin

Yeah, some people have and that created strange fuel delivery problems that
were extremely difficult to diagnose.
The fuel lines in case of the K-Jet need to be hard and they cannot stretch
under pressure. Any rubber or similar fuel hose will not work. If you look at
the inner construction of our hoses you will notice that there is a hard plastic
line inside. The rest, all that black rubbery stuff is there to protect the
inner hose.
Stick with high quality fuel lines meant for the DeLorean. Fuel lines like
brakes are two areas of the car where you should not try to save any money on.
It’s a safety issue.

Thanks
Harold. I should have figured out that it was a hose barb since all the banjo
bolts are hose barbed. Which brings up another question. Has anyone replaced
their fuel line with hose purchase from their local auto parts
store?

Happy
Thanksgiving everyone. I believe I am on the last hurtle to getting my car back
on the road. I had to remove the fuel distribution system to get at the clutch
slave cylinder which is in and bleed and ready to go. I reinstalled the fuel
distribution system and found a leak in the hose going to the WOR. Got a new
hose, installed it and then found a leak in the hose from the frequency valve (
the shorter hose). I guess the 30 yr old hoses didn't like the jostling around.
I can't determine how this hose is connected to
the valve. It is not a banjo or any kind of threaded connection and there is no
clamp on it. Could it just be a hose barb? I want to be sure before I try and
disconnect it. I don't want to damage the frequency valve, have you seen what
those things cost?
Thanks for any help or
suggestions.
Steve
