Replacing fuel lines

[Chogf22]

All,

I'm replacing a bunch of my flexible fuel lines as they are getting old and inflexible. After searching for an hour through various threads, I'm giving up and asking What size lines do i need for the header tank lines, and what about the bigger line from the main tanks in the wing root? I have gathered enough to see that Aeroquip 303 with firesleeve is a recommended application. Thanks in advance!

I might look for something without wire core for connections behind the firewall, if you are using hose clamps (tanks).

If this a stock cub.
Hose connections with clamps uses MIL 6000. (No wire braid)
3/8 ID for main lines.
1/4 ID for gage connections and smaller header tank connections.

For your line from firewall to carb it is common to use 303 aeroquip or equvelant plus the firesleeve.

I like the integrated silicone fire sleeve It’s real nice, cleans easy, and does not absorb oil.

Since we are on the subject. These just arrived for a Mooney that we have in the shop.

These came from Herber Aircraft Service. ( Call Gary - 310-322-9575 Ext 215)

ive quit building hoses and just send them out and have that done. It’s about the same price for the customer and a much nicer hose.

I recently saw a 180 on the ramp at my airport which had firesleeved brake lines.
Never seen or heard of this before, seems like overkill to me. ??

Maybe they are using the brakes too much and expecting a fire [emoji849]

It was probably an old fuel servo to flow divider line....
