All,

I have a Honda GC160 on my pressure washer.

There are three (3) pieces of tubing: tank to pump, pump to carb, & pump to crankcase.

Before I drive 30-40 miles for tubing, any idea what the tubing sizes are? 3/16, 1/4. metric?

Thanks in advance

That is rather small, like 1/8. My guess is 1/4 ??

I would had thought those that work on these engines would know these hoses are formed fitted and not just any old hose will work or at least that is what the service manual indicates.

This forum has some crazy formating. Something is wrong.

Anyway, it looks like I need to obtain the form-fitting tubes.

Take a piece of the line with you and match it.

That was my initial thought.

It turns out that some ends have to accomodate different diameters. May bite the bullet and just pay for form fitted tubes. Damn they're expensive.

Another option that I've done many times, get some line of the larger diameter to route to where it terminates onto the smaller barb fitting. Use a short piece of the smaller diameter tubing [a piece of the old bad one] on the barb fitting and slide the larger dia tubing over the smaller tubing. If need be, you can but a cable tie or other clamp on it, or even glue the two tubes together with a proper glue/sealant, but it's rarely needed. There are many variations on this theme, depending upon how much room you have and the various diameters, but there are ways to make it work.

Yes. I have done that before.

Another issue is kinking. I just tried a piece of silicon tubing for the crankcase to fuel pump. The tubing stretched OK (2 diff nipple diameters) but kinked.

If the hose is too short or the wall thickness is too thin, or both, it would be more prone to kinking. It is exposed to vacuum/pressure as the piston cycles up/down, causing the crankcase/cylinder volume to fluctuate.

I have the same 40 mile drive for everything, gone half a day . I have pushed a piece of steel brake line inside of the hose then bend it, leave it in there , no kink , then say it was like that when you got it .
