Re - HOW TO GET RID OF LAST OF CROOK FUEL IN A BUILT IN FUEL TANK

[patrol50]

Hi all - have a problem - my quintrex coast runner has a built in 60 L fuel tank of course and i got some crook fuel ( both water and some greenish looking crap mixed in WITH it ) when I WAS up north recently in it - fortunately i did not run the 60 hp ob that day on the main tank as only put it in the river so ran it on the portable auxillary 20 l tank which was ok fuel

Have drained out the crap fuel out now but reckon i do need to flush the tank out as probably a few litres still in there so any suggestions as how to best to do that with a built in 60 L tank - read somewhere i think that metho is good for that but any other experienced advice would be appreciated

cheers and thanks

http://www.fueldoctors.com/ add some fuel or metho with it and slosh it round and hand pump the bulb till its it empty again.. remove your filter if its before the bulb.

yeah fuel doctor is the go I was working with they guys when the developed this stuff and it works great

[ifishcq1]

park the boat with the pickup at the lowest point
then disconnect the outlet tube from the motor and take off the end and put the hose into a bucket
then put a couple of pound of pressure through the breather (I used a compresser turned down low so I didn't pop the tank)
this is pretty well the best way short of pulling you tank out
it gets as much crud and water out as possible
then use clean fuel and check your water trap when you pump the new fuel through
I got the idea when I saw a guy blow back into a bong many years ago, all the water and crap came out the hose

Don't put in additives to compensate for contaminated fuel in the first place or you will end up with a bigger problem and mess. additives are not miracle products and they are designed to treat good quality fuel in the first place.
Drain your tank like ifishcq1 said is a good idea.

Isn't the floor removable in a Quintrex?

yep it is noelm - crap piece of 16 mm structural ply with marine carpet glued to it that softens up real fast if it gets wet ( dont get me started on quintrex QA system ) but on a quick inspection it looked like the fuel tank may be very hard to remove - will have a good look at it when i get the floor out at over christmas - nothing on a quintrex coast runner is an easy fix

thanks captain rednut good advice i am uneasy about adding additives as well although 4 or 5 litres metho should be ok - and yep reckon ifshcq suggestion is the way to go

Pull the tank out and drain it, then flush it, and replace all your lines as well. Easier to do that in the shed than be caught out in the briney. My 2 cents.

[Noelm]

Yep, that's why I asked if the floor comes out, do it once and do it properly, no brainer as far as I can see.

Seems like a lot of hard work just to pull a bong!
