Title: fuel line
Post by: tvrc18 on August 12, 2008, 06:53:51 PM
This may be a stupid question but I will ask any way. Noticed that the fuel petcocks I have are for 1/4 line and the T is 1/4 but the Bing inlet is 3/16. The plastic fuel filter is also 1/4. Does one just force the small line on the filter so it will fit tight on the carb? Terry

Hmmm, that is interesting, the stock pitcocks as  remember is a bit smaller than 1/4 inch. but the bing inlet being 3/16 seems odd.. On my maico I had to use 3/16 inch fuel line from the pitcock to the fuel filter but after that I use 1/4 inch  It has held up just fine that way for a couple of years.... hope this helps...

Terry,
 Yes. We use a hair dryer to soften the line then push it on. A lighter will work but make sure no fuel has been in the line.
 You can find T's at auto parts houses that go from 1/4 in to 3/16 out and they do make fuel filters ( for yard equipment ) 3/16 if you look for them. Then you can run 1/4 to the T from the petcocks and 3/16 from the T to the filter and the carb.
Hope this helped ,

Thanks for the help. I will look for one of those T's or just heat the small fuel line.

 We found 2 ways on line to do the 1/4 to 3/16 adapt. The first was brass T reducer from MacMaster-Carr.

The auto parts house does not carry the plastic T's any longer so this should be a good replacement.
We also found a Fuel Filter that goes from 1/4 to 3/16 online

 that is the easiest way to do the same job.
Just double check that one end , the input end is 1/4 and one end , the out put end is 3/16.
Hope this helped out.

The inlet barb on my model 84 Bings are 6mm. I dont have any of them, but I guess the older screw on top Bings have a smaller inlet? At any rate, I use Honda 5.5mm fuel line, its very soft and will easily stretch over 1/4 (6.35mm) T fittings and the 6mm carb inlet.

Thanks for the help and all the input on this fuel line issue. I hope to have my tank back from the painter soon and will be needing to try one of these options.
