Topic: Fuel line and T-Fittings

[Shiftredline]

Ok guys, First I want to thanks everyone here making this great site. With that being said, i have a 76 cb550k that i just got running today. I have been slowly working on this this for the last 1 1/2 years.

Yes I have used the search function:
I have notice some on here have had to change petcocks and that the original had two out let and the new has one. I did what some one here said to and that was to buy a T-fitting. I notice when I went out for the first time today that is the bike was running real strong and then it was only running on two cylinders. I believe this is from uneven flow of fuel from the t fitting. If the bike is straight up and down (Center Stand) the bike is fine. I noticed this when i was turning.

Can someone send me a pic of the set up they have to give me an Idea.

Thanks

I would like to help but I have the stock fuel petcock with two outlets on my 74 550K.  I'm assuming you replaced your stock petcock with a pingel or something similar.  What was your rationale for doing this?  I've considered doing this since the petcock never really seems to shut completely off.

  Sorry, no pics at the moment. I'll try and describe my set-up as best as possible.

  "T" fitting is placed upright at the back of the carbs, just above fuel inlet for 1&2 carbs. Single line from petcock attached to the left arm of the "T". 1&2 inlet line is very short(less than 2") and attaches to the bottom leg of the "T". 3&4 inlet line is about 5" long, or "just enough" to reach the fuel inlet. The shorter the length of line to 3&4, the more the "T" will tilt to the right allowing gravity to do its job getting fuel to those carbs.

I think I understand. What I did was a half inch line from petcock to the t-fitting then just connected the rest of the fuel lines in a way that they dont kink. Would a y fitting work better the way you have it. I will try to post a pic of what i have. Thanks

My tank was so rusted that I could not rebuild the petcock. Sad thing is service honda does not carry the original petcock or any thing close. I did find the one I needed on ebay but it only had a single outlet instead of two.

My 360 petcock (2 outlets) was leaking and I noticed a 79/80 would fit but it had a single outlet. 
Just tee'd it to the carbs and has been fine.

I've had the same issue with my petcock not turning off all the way. I took it apart and cleaned it out. All I accomplished was breaking the dome and making it worse. If you want, you can read about it on my blog. 1976 CB550

Only the 76 550k came with different style petcock. It is a single threat bung style. I was able to get a nos of the petcock but with one outlet instead of two. They discontinued the original.
