Any good ideas for cleaning the inside of this line.I have already ran a piece of wire through the line ,hooked my compressor to the line.When i put my tank back in the car and put alittle bit of gas in the tank [3 gallons] the gas barely trickles out of the end of the copper line.It should be flowing out right?

Copper line? What line to you mean? The line through the tunnel? Or the tank outlet?
(Incidentally, even if it looks to be copper, it's only copper plating. VW did not use copper fuel line, the factory lines were steel)

Do you have a fuel reserve lever/valve? Those can get old/buggered up and act like a clogged fuel line. The brass screen in the tank can also get clogged and restrict flow.

Id clean out the gas tank. Take it out carefully, watch the tank's vent hose.
Check that in-tank filter. Id replace that, then you know.
A trick I have done over the years re: fuel lines, etc. is buy some cheap clear vinyl hose - of the right size - that you can get at Ace Hardware by the foot, and place some at each end of the metal line. Put the lower hose into some laquer thinner and suck on the other end of the line until you see the thinner starting to come up out of the clear tubing.
(Give yourself enough tubing so that you wont suck the thinner right into your mouth.) (And DONT breath in the fumes). If you can perform this task, you can then release the fluid back into the container along with all the contaminants in the line. Do it numerous time until your fluid is clear of contamination, and then you know your line is clean.
I know it sounds scary but if youre up to it, then its a good way to make sure your metal tubing lines are clear. |

#1 Yeah - you should have a good stream of fuel.
#2 Make sure its not the tank
#3 When blowing air through the line in the tunnel - tie a white sock or rag over the other end to tell if you have any debris coming out.

it may have been less work to just replace the metal fuel line  |
