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.

Nice job John and thanks for the help on a source.

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.

Try "Wicks Aircraft Supply
, they carry all sizes of "T's" and some are mil spec and fuel safe.
go to any autozone. they have packages of various size plastic tees for auto vacuuum applications. they work well and they are dirt cheap. chi jer
