Super Jet Water line and fuel line diameters?

[catfish4767]

What size lines do you guys run? I want to replace my water lines with a red line and found high pressure air hose by the foot at Ace Hardware. It was 5/8" OD and 3/8" ID. Thats big enough for water lines isnt it?

Fuel Lines I was going to use 1/2" OD and 1/4" ID. Or should I stick with the 5/8 line for everything? Thanks for the help

You're correct. 3/4" for cooling and 1/4" for fuel.

3/8 for cooling

1/4 for fuel

IDs matter, not OD. Unless you have huge CC engines, our cooling lines are all 3/8" ID. Fuel line is likely 1/4".

That's what I thought and ran on my 550s but didn't know if it was the same for a SN. Thanks guys
