Hi SM,
We recently had an issue when we embarked on a 3.5 weeks trip to outback SA. After 7 days, we arrived in Farina efore going to innamincka. I thought we had a dodby hand pump, but it turns out we ran the 89l tank on the Omeo dry, with minimal use, no showers or anything.
Turns out when I was filling the tank I was filling it too fast and the neck of the filler was so sullo f water it was filling the breather and the filler was overflowing heaps. Turns out that it was just that the breather was full of water, but unfortnuately the tank wasnt.
the side to side slosh method is ok, but I prefer the tap tap tap method, but it involves getting down on the ground etc. I'm thinking of whacking a gague in, but its a bitof work. Anyway...lesson learnt. double andtriple check the tank to see if its full. I'm gonna try removing the fittings and stick it waaaaaaaay down the filler......
A simple and quick gauge that is 100% accurate all the time is also the cheapest I know.
You need 2 "T" pieces to fit your tank hoses, 6 hose clamps, and enough clear hose to go the distance.
At the base of you water tank is your drain, put a 'T' piece here on the tank side so water always can flow into the 'T' before the plug.
Put the other 'T' piece on the filler hose that runs to the top of your tank.
Now join with the CLEAR hose. It doesn't matter if the clear hose isn't straight up & down it will always show the true level of water.
Also forgot to mention an extra tip to this:
2x small squares of plastic fly screen mesh or similar and 1 bright coloured round float (small enough to fit freely inside the clear hose) have seen ball or washer shaped used.
Put mesh over the 'T' piece's both ends of clear hose before joining the hose.
Put bottom hose on 1st then insert float before attaching top of hose.
Mesh keeps you float within your new gauge and also keeps possible obstruction out.
