fuel line

[gavinvader]

I know Jim had a post earlier that shadetree has 7/32 pink fuel line.......what is the exact size for primer line?  and is there any other application on an invader that calls for any different sizes?  I want to replace all fuel lines after i get engine back together

1/4" line will work if you cant find 7/32",,, you just need to use clamps or zip-ties

primer line is 1/8"

you'll probably need 1/4" for the fuel pump pulse line,,, and the oil tank to pump line... (the fittings are a little too big for 7/32" unless you heat the line up a little)

dont forget a fuel filter,,, clogged jets = disaster

me personally,, i use 1/4" and 4" zip-ties for everything... a local shop has nice stuff for pretty cheap and i can have it now if i need it...

I can order a roll of blue poly 7/32" if that is something you guys are interested in.  I already stock 1/8", 3/16" (used on powerjet carbs), & 1/4".

I have had the blue line leak after a year or so, the pink(ish) stuff seems to hold out a bit longer. I don't care for the hose clamp stuff so I use the 7/32 stuff (except for the tank to the fuel pump)

Would be nice to have a supplier that would sell smaller chunks than a 50 ft roll.

There must be different kinds of blue.  I had someone tell me last weekend that they used a blue that was hard after a year.  My current blue line has been on my Sportfire for 5 years since I rebuilt it, still flexible, no issues.

Has to be.  Line on my Intruder is 5 yrs old too and is still flexible.
