Water Tanks

[MAC03]

Hi brains trust, we have a 16.67-5OB and i am having trouble filling the water tanks to full capacity or so the gauge is telling me 3/4 and the rear tank is a complete ass to get any water in unless you have 4 hours to waste. Any help would be great. Mark.

Hi @MAC03. You should be able to see a clear 1 inch pipe from the filler to the tank. Sometimes they get squashed in between chassis cut-outs or kinked when installed. There's also a smaller breather pipe which returns back to the filler point.
They are never super fast to fill but it sounds like there's a blockage most likely from a kinked or curved run to the tank.

I think @twscoot is on the money there

if the breather is blocked, or too many "kinks" in the line - its a mongrel

When checking out @twscoot 's suggestion have a look and see if there is air in any of the "High Spots"... Could be as simple as an air lock?
Re-route that section of hose as straight as possible (and low if possible). Or alternatively pull that section of hose down when filling and see if it makes any difference?

Thanks all i will give it a go.

Had the same problem so i took the fitting out from the water filler point simple enough take the hose of from inside and turn the fitting in the water filling housing and it comes out i then got a snap on male water fitting , if you heat the white fitting up with a heat gun you can push the snap fitting into the water filling housing , just be sure not to push in to far as the female fitting wont snap on if you do , you can then pressure fill the tanks from a garden hose i also shorten the front tank breather up to make sure the tank filled easier
