5035 running out of fuel

   / 5035 running out of fuel #22  
just my 2cents worth but before I spent all the time and effort on replacing fuel lines etc. I would:
1. drain all the fuel out including the lines and filter bowl.
2. pour some clean fuel thru to wash it out.
3. replace all of the fuel filters, clean any screens.
4. refill with clean fuel + additive and prime.

I have spent more than my fair share of time tracking down gremlins that turn out to be just bad fuel, but it is usually the last thing that you look for. anything that sits for long periods like boats, tractors and motorcycles tend to develop fuel problems.

may not be it but if it solves the problem it is a lot less expensive/ time consuming.
Good luck and let us know how it goes.

Good advice sir. You are right for sure. And I'll have a nice clean fuel tank when I'm done, even if it doesn't fix it.
I believe I found where the tank drain plug is during a web search, so if it's there, it should be relatively. easy to do the job.
I will keep you updated.
Thanks again.

My 4550 had an issue like yours. Took it to dealer under warranty. Dealer found that the screen at the tank shutoff valve was pluged up with debris. I believe they just removed the shutoff valve to get to the screen

That's what I have been talking about!

but there is a factory-installed screen in the outlet.
Do you mean inlet? (Where you pour the fuel into the tank)

No, at the bottom of my tank there is a fuel shutoff valve that feeds the fuel to the engine. It's so you can shut off fuel from the tank if necessary. I was told that there is a screen on that valve that got plugged with debris in the tank.
Check your tank for a valve that goes from the bottom of the tank to your fuel line to the engine.
If there is a valve you may need to drain the tank to remove the valve unless you can unscrew the valve and quickly plug the tank.
Proberly easier to drain the tank

Thank you for the input Svendawg. As Fx suggested, it will be a cheaper, simpler check to do before going through the hassle of swapping/repairing the fuel lines, although that seems to be inevitable.

I did not see any sort of tank shutoff valve. I believe I will have to remove the protective metal plate that is blocking any sort of view of the bottom of the tank.
this is the best I can come up with for a parts breakdown of the 5035's fuel tank, although this view is for a 4035, which I believe are somewhat the same except for the extra cylinder for the 5035. Can I assume item 29 is a drain valve?
This image, IMO, is not very helpfull as far as fuel lines used or location of the tank shutoff valve location but it's the best I can find.

Note item 31. That is the screen filter for adding fuel to the tank.
It is in place and has no tears or damage.

Appreciate the input.

Yes, fx. Svendawg concurs.
Yes. inlet. typo on my part.
Number 31 in the diagram.
I will begin the drain and clean upon arrival of the borescope.
Need to find where that tank shutoff valve is though.

Appreciate your input.
Will keep providing updates as I progress.

Good input Svendawg. I believe I will have to remove the protective sheet metal that is covering the bottom of the tank before I will see that fuel shutoff valve. I'll remove the plate and report back.
The image I posted shows what may be the drain plug as item 21. I did not see it but may not have gone far enough along the tank to see that low-hanging section.
Or it may be covered by more protective sheet metal.

Borescope should be here tomorrow. I'll begin the drain and clean task soon after and will keep this post updated.

Thanks All for the recommendations.
Appreciated.
