fuel line routing - pics needed

[Svenn Ryen]

The lines from the tanks to the switch are 1/4!!! But from pump to carb the remains of what seems to be an original tubing is 5/16.

Does anyone have pics of the tubing from filter to pump and pump to carb?

Hi Svenn

First I don't know why yours would change from one size to another going through the pump none of mine change size the are all 5/16 though I will confirm the size.

Now for more pictures of the routing of the lines take a look at http://canadianmilitarypattern.com/H...INE%20WORK.htm which as a lot of shots of the engine work and close ups of the fuel, vacuum advance, and PCV tubes and the routing. Remember any photo in a blue frame has a high resolution version of the photo linked just click on the image.

You will note that the many photos of the HUP are of the uncleaned engine, I took these as the majority of the tubing and routing was original so I took these photos to document how things ran.

Let me know if these don't solve your questions, I've got more photos.

Hi Phil.

Did you check the OD on your lines?

And any pics of line from filter to pump?

Hi Svenn

I checked today the fuel line size on my HUP 5/16 steel tubing tanks to carb.

I'm just working on the fuel lines for my CMP. I am wondering if anyone has a source for the two grommets that are mounted in the frame where the lines cross through?

.... he had some nice felt gromlets at one time.....

Or take 1/4 in rubber hose.... slice lenght wise cut to proper lenght to fit the circumference of the hole.....squish it in place....... I also covered my fuel lines with a sliced section of 5/16 rubber hose...fastened with SS small hose clamps in any high rish area.......

Cheers
