RagunCajun Posted May 19, 2009 Report Share Posted May 19, 2009 I been noticing fuel leaking every so often from where the fuel tubing meets the carb. The little brass outlet. It seems the "nipple" or bulge could be a tad bigger because it's not sealing up as well as the stock carbs did. Even with the fuel line clamp on there it still leaks. I just put a new piece of tubing some RTV gasket maker on one(left side) giving me problems. I heated the line up with a hair dryer before and after to help the line flex and settle. That will hopefully seal it up nice and good. Anyone else had this issue? If so, how did you fix it? The fuel line is just the regular one from FAST. Worked fine in the past. It's just that these carbs seem to have a slightly smaller bulge where the fuel line connects. picture for reference: http://rc.superdave2u.com/MyBanshee/banshe...b%20problem.gif Quote Link to comment Share on other sites More sharing options...
BellicoseBanshee Posted May 19, 2009 Report Share Posted May 19, 2009 On my 35PWKs, I use small hose clamps rather than the wire-style claps. I also route my fuel line to ensure the fuel line bends around the pipe and is straight inline close to the barb, or at least the best it can be with cannons (Shearers)...

DallasGDub Posted May 19, 2009 Report Share Posted May 19, 2009 I also had this problem with the wire clamps. I switched to small hose clamps and problem was solved. My 28PWKS came with what looks to be the same tubing. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted May 20, 2009 Author Report Share Posted May 20, 2009 (edited) Fuel is still leaking from one the carbs. I guess ill have to try to find some smaller tubing. Guys the hose clamps arent working too well. One carb it works but the other i open the petcock and fuel pours out from the circled area in my OP.

TexasBansheeMan Posted May 20, 2009 Report Share Posted May 20, 2009 Small 1/4 clamps man, dis all you need. Quote Link to comment Share on other sites More sharing options...
DallasGDub Posted May 20, 2009 Report Share Posted May 20, 2009 Are you sure it is coming from the carb, and not running down the tube from the petcock or tank? I dont see how it could get past the hose clamp. That thing is air tight on mine. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted May 20, 2009 Author Report Share Posted May 20, 2009 (edited) 100% positive that's where it's leaking or should i say pooring out of. It has to be the fuel tubing im using. I will have to find some smaller tubing. I guess i will go to the hardware store tomorrow morning and get some. But then if it's too small, it wont fit on the "T". Hopefully heating it with a hair dryer will do the trick. There's a chance that tubing is split so ill replace it tomorrow morning. Either way i have to try smaller tubing. Grrrr.

TexasBansheeMan Posted May 20, 2009 Report Share Posted May 20, 2009 Never had to run smaller tubing on mine??? But I have a trick, boiling water, dip the tube in it for a few sec, slide it on the carb and clamp it. It should be soft enough to reform. The HD will likely not get it to the needed softness with out making it brittle. 2 diff kinds of heat. Quote Link to comment Share on other sites More sharing options...
LIM_Whiteboy4life Posted May 21, 2009 Report Share Posted May 21, 2009 Im using some home depot hose that barely fits the T with No clamps on the carbs and i have zero leaks... im not gonna leave it that way just saying.... hope this helps lol. :beer: Quote Link to comment Share on other sites More sharing options...
shanYE west Posted May 21, 2009 Report Share Posted May 21, 2009 I had a similar problem when I switched to the 5/16 line. I had to use 2 of the hose clamps.. but make sure you put the tightening screws on opposite side of the line Quote Link to comment Share on other sites More sharing options...
dragbanshee Posted May 21, 2009 Report Share Posted May 21, 2009 Same problem, when I got them a while back ran all new lines had it lookin good, turn the fuel on and was pouring out. Had to get some auto fuel line and a new T with smaller ends. Pain in the ASS. Tight now! pain to get off. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted May 21, 2009 Author Report Share Posted May 21, 2009 thanks for the help guys! What size and brand did you use dragbanshee? To update yall, i just went put a new vynal line from the T to the carb that was leaking. I went get the cheap 28 cent a foot vynal line from the hardware store. I then tightened the hell out of the hose clamp. No leak at all. Hopefully that takes care of my bubbles in my line. http://rc.superdave2u.com/MyBanshee/fuel%2...1%205-20-09.JPG My bike kinda cuts out at WOT after a few seconds but im pretty sure that's why. Can a dirty screen/filter in the tank cause air bubbles in the line? I noticed my fuel isnt flowing to well right now. Probably cuz im so damn low from all the fuel leaking. Ill go mix up 3 gallons in the morning and see what i can do. Clean it etc. Quote Link to comment Share on other sites More sharing options...
dragbanshee Posted May 21, 2009 Report Share Posted May 21, 2009 Im not sure, went to auto parts store and got a package of T's assortment and Im thinkin 3/16 maybe 1/4" fuel line and made it work. Tired of f>>kin with it! Keep an eye on that line if its not fuel line, never know! Quote Link to comment Share on other sites More sharing options...
Woolfman Posted May 21, 2009 Report Share Posted May 21, 2009 Can a dirty screen/filter in the tank cause air bubbles in the line? I noticed my fuel isnt flowing to well right now. Probably cuz im so damn low from all the fuel leaking. Ill go mix up 3 gallons in the morning and see what i can do. Clean it etc. I would have to go with no. The air has to come from some where and dirt doesn't make air. Dirty screens cause slow flow and could cause your WOT problem but not bubbles.

Ill go mix up 3 gallons in the morning and see what i can do. Clean it etc. I had the same bubble in mine after I switched to the OKO's, The supply line from the tank was almost vertical, at the connection of the T. I shortened the lines to the carbs and the bubble went away. When banging on her hard the bubble would go away, but com back after I got out of the gas or let it sit for a while. After I changed the length I had 0 problems with it. Quote Link to comment Share on other sites More sharing options...
