fuel line size??

[pitmaster]

ok i was wondering if the inside diamitor matters i went from a os18tm to a os30
just wondering if i need to go with a bigger inside diamator line.

also fuel line how long does it need to be from tank to carb.

nope , you dont need to change fuel lines , and you should have about 10 to 12 inches of line i think , pressure line is about 6, but some may say otherwise, thats what i got.

Well that is a good question Pitmaster I bought some bigger I.D. hose to see if I could get a richer fuel delivery. but havent put it on yet. but will try it this week end and let you know what I come up with.

your pressure line can very due to motor size and enviornment, temp, Altitude, ect. so just experiment with it somtime when your just messin around.

man i took the line i had gotten from the lhs. and its super small i called the hobby store that put it on my duratrax and my revo. asked them what the i.d was. he had no clue but he said its for .10 -.15's so i asked him if he was f-ing retarded and was wondering why he put it on both my trucks. when i have 2 engines that are over that. god i can't even trust them to put lines on a truck. how messed up is that. all i asked him to do was put new lines on while i was looking in the store. looks like i will never ever go there again.

btw stock traxxas lines are 3.32 id standard and will fit .15 - .60 engines called os today after i got off phone today with lhs. thats what they told me.
he also told me that if you have to small of a i.d on a bigger engine you will run to lean but wont have much power. i thought that to be kinda odd.untel i tought about it and thats what my duratrax was doing.
