I am so fornicatingly angry with myself.....


I am an absolute pain in the bottom about many things, one of them is getting out of the damn vehicle when it's being refuelled to make sure the right nozzle goes in the hole.

So.

We all know what comes next right?

yup, pulled into the fuel station, phone rings, hand the keys over to the attendant for the first time in a very very long time, and ask him for a tankful of unleaded. BIG MISTAKE.

I mean, in my head, I've always thought it's just a little bit anal, because the diesel nozzle can't go into the unleaded neck - the checking is just a hangover from when I drove diesels more often. The attendant can't screw up - right?

WRONG.

sign the slip, off I go, 2km down the road the misfire starts....

pulled over and turned it off immediately. sighed. picked up the slip. yes. diesel. f******* hell. .




SO - for anyone who is interested, the JK fuel relay is actually soldered into the TIPM. I mean. really? FFS.

SO - to run the pump without the engine running you pull fuse M25 and put a test light on it. one pole will go live for 5 seconds when you turn the ignition on, and then go off. Apply a wire to positive to the other pole. fuel pump will run (you have bypassed the relay)

for interest sake, it takes around an hour for the pump to pump out 8 5litres of fuel . sigh.

It restarted with a bit of grumbling and puffing and blue smoke but she's back to her old howling self again now the tank has been refilled with nice clean cold unleaded.

Ironically, the 'check engine' which has been on for 40 000km or so because one of the o2 sensors is unhappy has no gone off and the diagnostics indicate all the o2 sensors are now happy.

more WTF for the day.

It’s actually interesting. I always wondered how the hell you get the wrong fuel out.

What would you do if petrol was put into a diesel car?

petrol in a diesel vehicle is a much worse thing to happen.

In a petrol engine, diesel just doesn't ignite from the ignition spark. you might oil up the plugs but thats about it. clean it out and it will chug until the fuel runs clean.

petrol in a diesel can shatter a piston. it rattles badly, temperatures go up etc.

but on a modern common rail diesel it's the same procedure. unclip the fuel line at the fuel rail, bypass the pump relay so the pump runs until the tank is empty. chuck what came out and fill up with fresh (correct) fuel

Glad it all turned out ok.
Strange enough, my old man believed a little diesel now and then in the tank, would help with lubrication. Don't know what all it could help with though.

There must have been 2SO in the diesel and it cleaned the O2 sensor(s)

But on a serious note, I'm glad all is OK, there should be no serious problems.

If the pkugs get a bit oiled up a good few kms driving will burn any oil off.

Similar thing happened to my wife's Cross Polo TDI, but it was R100 petrol that was added to the tank, thankfully not a full tank, the car drove all the way home, but then wouldn't start, I ran the fuel pump as much as possible, when I got it started I added 25 litres diesel and drove the the petrol station and filled up so any left over petrol would be diluted into a full tank, sold that car and it never had any issues related to that day

New diesel cars have a 'DIESEL' sticker on the inside of the filler flap? Yes?

0 - 100 in under 10 seconds for the first time ever... but only once...

Well, a wrangler doesn’t have a filler flap.

But generally , yes, there is a diesel sign somewhere. The diesel wranglers have one inside the recess.

I went to the station , apparently the attendant couldn’t get the nozzle in so he just held it against the neck and the prsssure must have forced the flap open .

That would be amazing...

no fuel tank sump plug ?

nope.

that would be something to knock off when offroad.

It's not something you really see on modern road cars.

Can you imagine how often your tank would be empty if they did?

The old Suzuki SJ has a plug in the tank, which came in useful the day I dunked it in water above the level of the petrol cap.
The drain plug on the carb float bowl also came in handy that day.

Looking around the net I see that
‘ mod’ cars dont tend to have fuel sump plugs ..
... seems that as plastic tanks came in such plugs stopped being integrated ...
though I suspect its another example of economic simplification via ‘ expendible ‘ components being eliminated !
Sell customer less for higher price .

That said plastic tanks are however better.
Can readily be made any shape to fit underside
of vehicle and can be easily replaced
lighter and ... dont rust ... !!! etc etc

... but ,.. also ... much cheaper to make/supply

Yes I think drain plugs no longer standard
but this thread reflects dangers in fuel quality
or its compromising:

diesal in petrol or vice versa
parafine in diesal
water in garage tanks (&methanol/condensation)
grit in fuel tanks
fungus in diesal
(and even sabotage ...
... such as pee or sugar into fuel tanks!)
etc etc
... and so, off road and overlanding especially,
the need to drain/clean a tank can unfortunately be a very necessary thing.
