fuel line size?

[outlander3001]

Hi all. I am ready to install my fuel pressure sensor, but I want to make sure I have all the right part before I start messing with the fuel line. I am planning on installing a new hose and keep the stock hose untouched in case I need to put it back. Does anyone know what the inner diameter of the fuel line hose is coming from the firewall to the fuel rail? I looked at the service manual, but it only tells you how to disconnect the fuel line, not the size of the hose.
Also, I noticed that the stock installation does not use hose clamps where it is pushed over barb connections. Is this ok, or should I go ahead and put clamps in when I replace it?
Lastly, anyone have a favorite online shop with good selection of hoses, connectors, clamps, etc.? Somewhere I can get everything in one place?
Thanks in advance for the help!

first off, how about some details. is it an electric or mechanical guage. what kind of car. protege? 3? why are you installing this?

the size of the line is 3/8". get yourself some thick s***. yes, clamp the line at the barb even though the stock setup does not require it. im not sure what setup you plan on running or are running, but it never hurts. when i tapped into my fuel line for my mech pressure gauge, once i started my car it was not clamped at the barb and it blew off and i lost about a gallon of gas until i figured out exactly what had happened. you can remove the stock line completely from the barb to the fuel rail and clamp the new line directly to the barb with a metal clamp thing.

also, dont forget the line closest to the driver's side is the feed and the one to the left of it is the return, and the gauge goes between the feed and the fuel rail. there should be almost no need for you to do anything between the barb and the firewall. that sounds kinda risky to me like if you **** something up, you might have to make a trip to a dealer for a really expensive part that isnt worth s***.

i actually have always used 5/16 inside diameter lines for fuel.

electrical. p5. because I need to fill in the gap above my stereo, and a couple gauges sounded like a good idea... for cosmetic reason really...

hmmm...3/8 line always works well for me with a clamp
