Routing fuel lines

[Tatesteinborn]

On my 1997 GTI, i got it without an engine. I recently put an engine into it. All the lines were still there but I'm confused on the fuel lines. Does the line running from the water separator feed the carb and the other the is the return????

Yes. If it still has the gray tempo lines you need to replace them all and also replace or thoroughly clean the fuel selector valve.

I have ran new lines but I will clean the selector. I put a in line fuel filter, do you think that could restrict fuel flow or no???

 

[Ankeneyou]

The bad part about paper filters is that if they get any water in them they can restrict flow. If it's after the water strainer you are probably ok or get the K &N mesh screen type filter.

It's after so I will check to make sure, how long should it take to get the fuel all the way threw the lines???

Maybe 30 seconds of cranking in 5-7 second intervals to ensure you don't fry the starter.

For some reason I have cranked it about 10-15 times and it still won't fire over

Fuel selector is On and you are sure all lines are connected correctly? The fuel baffle lists On/RES/RET/Vent near where all 4 lines connect.

Check pulse line from the crankcase also. Did you rebuild carbs with new mikuni kits and ensure fuel pump is working?

I reconnect the lines exactly how they were before. It looks like there needs to be hose clamp on the pulse line. I replaced and put new seals in the carbs. I will disconnect the line to the farthest carb,it has a dual carb set up, and check if it's feeding fuel. Thanks for the help

Fuel inlet is on the bottom fitting of carb
