So the bastarbing fuel line was leaking,
I must have linked it at some stage.
$25 / 10ft worth of nylon 5/8"fuel line ordered.
Not knicking the barbs on the fittings was taken care of by burning off the old line.
Then just heated the barbs and the line to get them together. All seems to be leak free now thankfully!
What seems like an infinity later, I'm very well acquainted with everything leaking under the car.
Somehow I ended up with an extra 4 inches (TWSS) of fuel line and did a quick loop and additional bracket
A job I hope to never do again. It's not in tank fuel pump bad but I have crud in pretty much every orifice!
Great thing is that there's no visible crud/ varnish in the fuel up to the filter at least.
I ran some bigger fuel hose over it to sheath it around the engine bay, just kept it away from top so I could see the leaks if any !
The little 8mm bolt that holds the sheathing on entrance to the Bay was a bit of a pain in the face !
But done, hopefully forever!
