Nope uphill to the tank is to the right. My tank just has a hose barb on it.  Anyway here are a couple of more pix that might give you an idea or two.   O, if you still want a Uni sock filter I have a new one I'm not going to use. Ten bucks shipping and all. O then there's Excise tax, labor tax, State, Local, Federal tax, Hotel tax, and Carpet tax. That brings the total to ahhhhh hey Ten bucks. I'm not in the business so maybe Rebel won't chastise me for the sales pitch. The pix is kinda fuzzy, sorry.  RD |

I found out I've been tripping a little bit over the size of the barb. I stopped by Lowe's yesterday evening and talked to a guy that really knew his crap when it comes to thread and thread sizes. he hooked me up with just what I needed....except the part is 2 big. 5/8 in pipe thread ='s 1/2 or something like that. So I got a 1/2 size peice and yeah......it fits clean over the male nipple. I'll stop by there tonight and downsize the parts I currently have then hopefully it work like a champ. It's a lot easier then I was thinking or imagining. I also have the fuel line hose to compare peices too. I'm getting wiser at least  O yeah....once I put this manual petcock in place, what do I do with the vaccume hose that's currently in use? I won't be needing it at all correct? I had fun yesterday and ordered 1 of the air scoops off ebay for the bling factor  and I ordered a torque spring??  hahaha I read where it can add more off the line snap and and more top end kinda thing and it was $10. I figure why not. Now I just gotta figure out where to install it ;D RD, PM will be sent regarding the UNI sock, thanks! |

You need to put a cap on any vacuum line or nipple that is not in use. Regarding the guy at Lowes, that is why I suggested finding somebody that had a few active brain cells. Getting somebody that knows what they have and how to use it makes things much easier from the start.

HA! i finally got the right size parts and got all excited. hooked everything up and and put some gas in. Immediately gas started dripped out everywhere I spliced  It's leaking where the 2 brace pieces fit together and on both sides of the petcock I put in. hehehe Don't forget to remind the n00bs to use clamps LOL  |

Script, One thing you need to make sure of when running a gravity feed fuel line. Make sure the line runs constantly down to the carburetor. It's ok to have a level stretch in it, but not dips. If you do air will be trapped in said dip and you will have feed problems. Your pix looks to have one.

rgr that RD, I did see the dip and I have an idea to make it level down a better but that's the next task after stopping the leaking. I troubleshot the leaking and it's coming from the brass nipple I installed lol! go figure, all this time and energy trying to figure it out and finally getting the right size (after making 4 or 5 trips total to the hardware store :  only to have fuel seep out of it. Is there some type of sealer I can put around the male nipple so I can screw the brass piece on tight and not have an leaking? Or maybe I'll just stick a hose on the end of it like RD did and get some kind of piece that'll work down from the bottom of the tank to the size of the fuel filter. grrrrrr  hahaha my wife just made a good point. the stock vaccume peice bolts on with no issues and no leaking. perhaps the peice I managed to put together doesn't have the exact same threads or something. |

If you need a new fitting, try one with a 90* instead of strait down
Then feed downhill from there, you can put the shutoff further on down
I always put my filter near the carb after the stop for ez service

As long as the fitting threaded on feeling like it was going on correctly, it is probably the right thread on it. A wrong thread would tend to mess it up and make it difficult to screw on. You can try some teflon tape on the fitting to stop the leak. I have heard of people using silicone on the threads, but I'd go with the teflon tape.
Somebody can correct me if I am wrong. The valve you replaced is a shut off device, it is not a pump. When the motor is started up vacuum opens the valve up and allows fuel to flow towards the carburetor. It is actually a safety device to prevent fuel leakage when the scooter is not in use. As far as I know any scooter that has a tank above the motor does not need a fuel pump, they just do or can run off of gravity. Once the line is connected on both ends, I don't really think a redirection up will effect the flow of gas becaus unless it goes above the level of the fuel in the tank, gravity will pull it down. The same thing happens when you siphon gas out of a tank, gas goes uphill until it comes over the top of the tank and then downhill to the end of the hose, if you take the hose end and raise it above the level of the gas in the tank, it stops flowing out.

I don't totally know what it is lol. It sounds like u could be correct. It does work via vacuum, I know that much and I think this devices causes my scoot to die sometimes but I'm not 100% certain. I'm doing this project for 2 reasons: 1 - to get the vacuum controlled whatever out of the picture. (my scooter company said the device might be bad and might create air related issues which kills my motor and leaves me on the side of the road) 2 - just to do it and get comfortable tinkering with the scoot ;D I'm gonna go by Lowe's again and get a 90* elbow, I like that idea and I'll look at getting some teflon tape and possible some rubber washers, unless gas will eat threw rubber? I have tomorrow off and the weekend's coming up, so I'll be tinkering with this little project for sure and hope to get all this ironed out and back on the road  |

yes, gas can erode regular rubber and give you problems. I can not recall the name of the kind of rubber you would need to use if you put rubber washers in there, it is what they make the fuel lines out of.
Take your adapter you created to a auto parts store and ask them if they have something like it that is one piece. Another thing you can try is to solder it to get rid of the leak where the two pieces join together. You would need some acid core solder and a propane torch to do that job, and oh, by the way you would want to remove it from the gas tanks and get a bit of distance between the two, unless of course you are fond of exploding fires.
If you want to try an solder it, all you need to do is warm the fittings with the torch and touch the joint with the solder, it should melt into the joint, make sure it goes all the way around the joint and it should be well sealed. You can not do that with the tank end of the adapter. Fumes would remain in the tank and would potentially cause an explosion, not a good idea for somebody that is not an expert.

aite cool... I used my original peice with teflon tape and no more leaking.... yay I tested a little bit around the block, so far so good. Will test more this weekend. What do u pro's think of my butchered rookie job lol  |

I don't see anything butchered, looks good to me. Is there any room for movement? You do need a little slack in the fuel line in my opinion, the motor does move up and down as you go over bumps and things.

I purchased the Uni.
And I also put the vacuumed controlled petcock back in place, after all that hard work lol.
My scoot still coughed and sputtered with the vacuumed controlled petcock out of the equation.
(That's what I was testing is too see if the manual petcock would resolve a fuel related starvation issues I would feel soon after filling up)
It didn't help, and the threads were a little off between the copper pieces I purchased and the male end of the gas tank so it was leaking just a little bit no matter what I did to fix it.
I did however check the breather hose at the top of the gas tank, it looked like it was pinched.
I re-routed that line and am still trying to test but the weather is getting colder and colder now that it's nearing winter time.

if you had even a little leak it is possible you were sucking air into the fuel line and getting problems from that.

hahaha
only to have fuel seep out of it.
