On this episode of project stoopid we are digging into high pressure fuel delivery methods. The system operates in the area of 45 PSI. The slaves in the dungeon are playing dumb. The fuel rail has these quick disconnect thingys that look similar to an air fitting. Without the threaded portion.

research finds everything from PTFE lined braided fuel line, aluminum tubing, AN fittings, nylon braided, hydraulic hose, all the way down to " just get regular fuel hose and claamps.
l have both halves of disconnect thingy, but the hose attached is a hard plastic stuff that appears to be shrunk on.
The run from the fuel cell to the pump is easy, just hose. (No pressure).
From the pump to filter to the regulator to the fuel rail reguire something else.
hard tubing isn't going to work. Anyone that has tried that has dealt with the leaks, cracks etc.
the fitting pictured is $50+ at Jegs so that won't work either.
So the question for our panel of experts:
What is the opinion of you smart as.. errr l mean experts?
yeah, l know 90% of ya guys are using gravity fed fuel.
