Oil & Fuel Mahindra 1526 clogged fuel tank

[Chicnranch]

There is obviously something obstructing the flow of fuel from my tank and I'm having a horrible time removing it. Would there be a solution beyond removing and cleaning the tank?

So what have you done so far to troubleshoot the problem? I guess I'm wondering why your having to remove the tank, are you sure the tank is the issue and not something else.

I let mine drain out over night (dribble at a time), then used a Rigid inspection camera (Under 100 bucks at Home Depot) to look at the bottom inside. Small bug was obstructing the fuel outlet, got it with a pair of 'grabber' tongs.

After the 2nd time, I fixed the problem with one of these inserted in the fuel outlet:

When gas level decreases to 1/4 or so, gas will reduce output flow to a dribble. If air is blown backwards into tank, regular flow is restored. I just read another 1526 owner had the identical problem I have. The parts diagram for this tank shows a screen filter in the fill neck. Mine is missing or has been pushed into the tank as the other gentleman discovered when he took the shroud and dash off to get to the top of the tank to remove the sending unit. He discovered a wasp in the bottom of the tank as well as the screen filter that should be at the top of the fill tube under the cap. If TnAndy has a 1526 and a camera can come in from the fill, I may try that. The fill has a right angle that my be hard to navigate a camera or snag tool past. Otherwise I will be pressed to duplicate the method that the other 1526 owner did to get inside the tank.

You said gas but I believe you use diesel. Since you can use air could you take a length of wire and push it up the hose and into the tank.

 

[Chicnranch]

It’s not in the hose, it is in the gas/diesel tank. I did make a small attempt to try to hook it with a wire though the hose and pull it through.

This is identical to my issue, so waiting on his reply to questions about easiest path to top of tank to open sending unit for internal access

We had an almost brand new Vermeer trencher will an obstruction in the fuel tank. Our mechanic disconnected the fuel line right before the filter, pinched off the return line, then used compressed air to blow whatever was in the tank out with the tank still full of fuel. He did all this while smoking a cigarette!

LOL, I was going to get an unvented gas cap and drill a hole for a Schrader valve, pressurize and watch it split the seams
