I have never ran a race car with a piece of fuel line just stuck in a hole.
The motors i have ran will blow any line out of a hole thus,changing the tuning on the motor,i have allways just screwed a small nipple into the pipe
and attach the fuel line to the nipple!
I dont see the problem with the repair advice?
The stab at the ntc3(ac) was just in fun,i try to add a little here and there
sorry if i steped out of line.
Cooking is my real gig, the race is the FUN.
See you soon
