BX23 fuel line size & where do I get it.

[leonz]

Nope, this isn't a lot of trouble.

So far, I've had to adjust the brakes, replaces the half front drive shaft for about $110, replace the fuel filters.

I think it probably just needs new clamps but I'll probably replace some of the fuel lines just in case.

A lot of trouble would be the transmission is bad or the engine is bad. So far this has been just stuff that should have been fixed by anyone who owned it.

As it says in my signature 1300 hours.

About your fuel lines you should invest in the Racor brand fuel line for your Kubota.

The Racor fuel tubing is made with woven reinforcement to prevent the fuel hose from collapsing due to the pressure gradient created by the indirect injection pump on your Kubota tractor.

The tractor uses fuel hose not fuel tubing for the fuel line.
What is the part number for 8mm diesel fuse hose ?
Can you provide a link to it ?

About your 'fuel hose'... go to any autoparts supplier, no one is making any secret superior hose... diesel fuel hose is as common today as gasoline hose..
Unless you are buying a shipping container of hose you will not be "investing" in fuel hose... just buy the amount you need, let the jobbers and distributors "invest" in warehouse inventory... KennyV

I've already got "my fuel hose".
It's 8mm diesel rated fuel hose.

I don't need any exotic fuel hose and never did and wouldn't have bought it if I could. All I want is OEM fuel hose.

But I sure as heck don't need the 1/4" tubing which is what the dealer sold me.

It's hard to get on in the confined space.
Oh sure you could do it, but why would I use a non OEM size.

The last time I hard to get metric tubing for gasoline it was hard enough. Diesel must even be harder. I didn't even start the discussion with a parts store which would have probably tried to convince me that 1/4" tubing is good enough if they didn't have metric.

I went to a supplier who sold me the right stuff the first time.

Perhaps things have changed, and perhaps I need to change my notions. I'll check just for fun.

I've replaced the hoses that I can get to easy and all have screw clamps on them.

I was thinking I was so smart getting metric fuel hose and ran into the made in USA 5/32 inch hose, clearly stamped 7.84 mm.

I should have just used 5/32 inch hose.

Sigh.

It stuttered a bit and one by one they went away.

I need to run up and down my 1200' hill a few times at full throttle and then stop at full throttle to duplicate test conditions.

Thank you everyone for all the help.

The missing is all gone.
It seems to work just fine now.
Ran it up and down my 1200' hill twise, moved some dirt, back dragged it.
Came to a stop at the top of the hill under full throttle and it's not missing at all.

To recap:

originally loss of power, and finally would not run or start.
probably bad fuel.
would start after after a few hours.

drained tank,
replaced filters, some spring hose clamps broke.
worked much better but stuttered after 10 minutes or so.
Always started.

replaced fuel lines with 8mm diesel hose.
It was for the most part in good shape, but it showed somewhat stretched I suppose.
5/16 inch should work perfectly, it's 7.94 mm and is easier to get.

replaced all hose clamps with worm screw clamps.

It works perfectly now.
No missing at all.

Thanks everyone for the suggestions and help.
