Siamese fuel line size and sources?

[John Gragg]

I found a decent pressure tank for my CD12 and QD15. Needs work, but decent.

I took one of the fittings off a motor to O’Reilly and tried to match the fuel lines. They (the fuel lines carb to fitting) ‘measure’ at 1/8″ ID, but the nipples refuse to go into that size hose. However, 5/32″ is perfect, so I bought some for the motors.

Now I’m trying to get my hands on 5/32″ siamese line and can’t find it anywhere?

West Marine has 1/8″ siamese, but like I said I’m pretty darn sure that is too small.

What size should I be getting and where can I get it?

Thanks in advance…

Sources for the dual line hose are MarineEngine, ebay, Amazon, NAPA. Some may have other places as well. Someone once posted this: “The OMC line is 5/32″ – If you want the more available/cheaper 3/16″ fuel line just go to your local Advance or other Auto parts store. No part number needed. I’m not sure Sierra sells it by the foot? I don’t see a part number for it anyways. I buy it in the 50′ roll. I have been told some NAPAs will sell the Sierra by the foot, but not my local one.”

Sierra use to be available at MarineEngine but not right now, but you could use that number 18-8051 or SIE18-8051 for searching the other sites.

John put a little heat on those 1/8″ lines and they will go right on.  Heat like a hair dryer or heat gun.
