Hi Folks,

Apparently (RACQ said) the solanoid which switches between the two tanks is stuffed. I've got a diesel '89 troopy, is it a big job to repair? It seems it doesnt completely switch from one tank to the other when you press the button which means it eventually _Affordable_Storage_Drawers.aspx air from an empty tank.

I usually switch tanks and leave a good 10 lires in there, but by the time the second tank gets to half full it has drawn the 10 litres from the first tank. Might explain why I've been getting such good fuel economy!

Then there is problems because its drawing from the first tank but theres nothing but air there so I stall and and have to let the air out if the lines, then 2 minutes later its stuffed again.

Any info would be appreciated, if its going to be pricey I might just switch them back and forwards evey quarter of a tank or so.

Cheers

Mistermister,
I had a similar problem with the solenoid on my aftermarket tank some years ago. Was able to take it apart. Some detritus from the tank had become stuck in the valves, and was stopping it from operating properly. Cleaned it up and all was well. Happened again later, but without a filter in the tank, was resigned to the fact that it would happen occasionally. Just a bugger of a thing to pull out, complicated by the fact that it was a dual valve with the return fuel lines switched as well. Very confusing with all the hoses running everywhere.
Cheers, Gerry

Had the same problem with my 97 hzj trayback.
Mine has 2 solenoid valves, one for fuel feed, other for return.
Its a fiddly job removing them, you have to get the lines off without getting too much juice up your arms, plug the pipes (I used .303 bullets), then make up a set of test leads so that the valves can be actuated whist you blow/flush the offending bits of ?? out (seemed to be a black rubbery looking stuff)
With mine it happened soon after purchase, but not being the type to use warranty claims etc. sorted it myself. Happened a few times after that, but not for 3-4yrs. now. The "whatever" it must be all gone.
It is an annoying problem, can be overcome, but am sure the solenoids would not be stuffed by it (only stuffed with it!)
good luck the kesh
