Replacement site glass tubing

I can’t recall which posting it was a question about replacing the site glass tubing. The photograph showed what looked to me to be reinforced water hose.
The question on the form was what were the dimensions of the tubing. I can’t find the post. (Was just looking at it! ??????)

We replaced ours on our ‘03 42EU couple of years back.

The dimensions on the tubing was 1/2 OD, 3/8” ID. Tygon tubing rated for Diesel fuels.

Attached is the receipt where it was purchased. I hope this helps.

McMaster Carr:

$ 0.98 / ft.

Flooting ball

I also placed a small floating plastic ball inside the line, and several black o-rings on the outside as adjustable markers.

I would not use the 98 cent a foot stuff from McMaster it is only rated at 120 degrees and my engine room can reach that temp . although the clearer stuff would be nice .

I was thinking the exact thing! My question is where and what do you get for the "red ball" float? TIA, Ken

I have used small fishing floats.

Hate to be stuck on easy but Same Place:

These are hollow aluminum 5/16" diameter. This assumes use of 1/2" od x 375" id hose. Other sizes are available as well.

Isn't your diesel in pretty colours over there?
Why would you need a float?

Here’s a discussion thread about tubing for sites tubes. Versilon/SE-200 sounds like the way to go. Pick up the discussion around post 6.

My pre-purchase survey tagged the plastic hoses in my sight gauges and required diesel rated hose, recommended Tygon which is what I purchased/installed after close.

The Black O-rings to record prior fuel level are a great idea and one that I will be copying.

As our hose is already in place, electrical ties do the same job.
