Fuel Line Sizes

[waffle429]

So I'm rebuilding a blaster, and I need ALL of the fuel line sizes. I have the oil pump removed. So that means I need sizes for:

Petcock to carb
Carb vents
Carb drain
Case vent

Thanks guys

[speedyslyder]

[Awk08]

. How about the case vent? 1/4" as well?

thats bigger, prolly 5/16" or 3/8"

 

[speedyslyder]

[waffle429]

[Herpderplol]

3/16 is smaller than 1/4 if you were thinking opposite??

1/4 tank to carb
3/16 carb drains/overflow

 

[speedyslyder]

nope i said i have 1/4 on my drain and it is loooooooooose it stays on but it is not the right size so there for it is not 1/4 next size down is 3/16. it is a blue parts unlimited line.

 

[Herpderplol]

all your ? marks got me confused... i was thinking you thought it was weird to run 3/16 on the drain

 

[speedyslyder]

im going to see if my shop has the 3/16 then ill know for sure ..today i bought 1/8 and it looks like it goes to a fisher price toy....my mistake guy at counter was not the guy i wanted to talk to lol and i was unpreppared i never bought them for a blaster carb before except the 1/4 sizes for the other 2 of them on there lol...mine was missing went i bought it so i did not have a example and im not bring my carb there sooo i guess thats what i get and i did not research it ....last minute although i did get some new grips and oem base gasket....shes coming apart again

WTS, has anyone heard of a measuring device called a rule or tape measure.

No need to take anything to the parts dealer other than a little bit of paper with the sizes written on it.

If you cannot explain your self it may so happen that the spare parts guy can read.

 

[speedyslyder]

i have digital caliper thank you

 

[waffle429]

Resolved: I was at my Yamaha dealer, and I asked the guy what size the carb vent is. He found the OEM Yamaha vent in the back and we measured it to be 1/8" inside diameter. Just to be clear, that is NOT 3/16". Like Blaaster said, they have these things called rulers... Lol

 

[speedyslyder]

alrighty then tommorow i will pull my lines and fit my 1/8 line if it dont fit then down to the store it is
