stevec Posted May 6, 2011 Share Posted May 6, 2011 The barb on the carb takes a 1/8" ID tube. The general set-up is to run 1/4" ID to an in-line filter, then 1/8" ID from the in-line filter to the carb. Quote Link to comment Share on other sites More sharing options...
dmpatanis Posted May 7, 2011 Author Share Posted May 7, 2011 To fit the 1/8"(3mm)fuel line in nipple of the carb WG-8 i must take off the white plastic in the carb nipple???... Quote Link to comment Share on other sites More sharing options...
stevec Posted May 7, 2011 Share Posted May 7, 2011 You can take it off, or run 1/4" tube. I prefer 1/8" ID tube to the carb as it seems to help with bubbles. I use the Bing blue alcohol resistant stuff as I find Tygon too soft. It's transparent so that you can see the bubbles and get paranoid about them like me!

enzo200500 Posted May 13, 2011 Share Posted May 13, 2011 There is normally an arrow moulded into the main body of the filter to show fuel direction. That looks OK in your picture. Quote Link to comment Share on other sites More sharing options...
dmpatanis Posted May 24, 2011 Author Share Posted May 24, 2011 Hello,i change the fuel line with Tygon. From the fuel tank in to filter i use 1/4'' line and from filter to the carb i use 1/8''. The motor runs fine but i saw that the filter i use doesn't fill of fuel.Why??? The 1/5 of the filter has fuel on it. I use the filter in the picture that i post.

stevec Posted May 25, 2011 Share Posted May 25, 2011 Ah. Now if you can find an answer to that I will be most impressed! I too have the same filter orientated vertically and it runs almost dry. I can only imagine that there is either a pick-up tube inside the paper element which runs close to the base of the filter bowl, or the fuel runs up inside the paper element without escaping into the bowl. I also get streams of bubbles occasionally from the filter to the carb and there is definately no leaks at the joints or in the filter (I have pressure tested the line). After changing ny fuel line/filter set up multiple times, the best advice I can give is that if it runs ok - forget about it! Steve Quote Link to comment Share on other sites More sharing options...
