On a larger scale I've seen that puff destroy 1/4" steel tanks.

You just aren't listening to a century of refinery and regulatory history. I'm sure you are very smart, but you are beating a dead horse.

Yes, I have sailed outside the Bay (just didn't write a book about those trips).

The thing of it is this; many of the people on this board are brilliant and amazing, and bragging--by any one--is embarrassing.

I'm guessing the actual risk is inattention. They get in the car, distracted, and drive off with the hose in the tank. That does happen.

But cell phone usage is way off topic!

Thanks for taking the time to prove thinwater’s point. That cup could represent a tank or bilge, the lighter, contacts changing state, hot exhaust, generator windings, static discharge…

Might there be a reason tank construction, location, venting requirements etc... varies based on its contents?

It would be irresponsible to have a discussion about adding gasoline to a system designed for diesel, without discussing the unintended consequences.

While in Australia, did you happen to visit Darwin? I hear its lovely...

If you have no leaks downstream between tank and injector I don't see a problem. Its not as if you have an empty but non gas free tank after carrying crude.... that can get ugly

No idea re the bug killing aspect.
What happens to the fumes, safely sitting in your tank, when you refuel?

They become displaced and flow out of your tank mixing with the surrounding air. Twenty gallons into your tank and 20 gallons of fumes exit your tank filler and your vent pipe but mainly out of your filler.

Same with your car which you will notice if you leave a door open.

A few years ago, I saw a lady driving down the road with the hose dragging on the pavement and the nozzle still in the tank. She noticed the hose, pulled off the road and stopped the car.

Later,
Dan

I was refuelling a car in Oregon recently and was told it is a regulation that an attendant has do the refilling. I don't know the details but maybe for that sort of reason and cell phones?

Re: Gasoline as a Diesel Stablizer

I thought I would add this. I stated we added a cup of gas to 5000 gal of diesel to kill the bugs. What I did not say is this fuel was used in a forge shop. It was in trucks with tanks that had only a pipe cap lightly on the tank. These trucks operated around the forge furnaces running at 2300 deg F while carrying steel at about 2100 deg F. We had tires burn off the trucks but never a fire with the fuel unless the truck first burned due to being stuck in the furnace. Then it just burned like diesel does and did not explode.

A cup in 5000gal. is different than 10 gal. in 200. I'd guess, if it was that easy it would be done at the refinery? One of the things was trying to light it, dah not vapors in an open cup. I'll bet you could put out a cigarette in a open top bucket of gas. Just my dumb ass opinion.

Completely off topic and not addressed to me; sorry. I visited Darwin a couple of years ago. Kakadu National Park some distance south is well worth a visit. Plenty of big crocodiles to see if you go to the right places. Southern winter is the best season.

I thought we were considering the explosive potential of vapours from fuel mixes.
They need a source of ignition. That could be a cell phone or a camera. Ask any expert. I'm not an expert but I have heard this directly from experts.

Re: Gasoline as a Diesel Stablizer

I am assuming the visiting Darwin comment implied missing out on a Darwin Award.

The Sailors Confessional section is the best place for this topic. Confess an action out of the norm and wait for the villagers, tar and feathers.

I try to keep my diesel tank topped off and don't use additives. Occasionally put used oil in tank if no recycle drum available. Never would consider gasoline. 130 gallon tank btw.

I'm guessing you wanted to retract Bay Sailor comment as soon as you typed it. Rum and coke moment, huh?

Looking for another pretty place to work on the boat.

No argument with me but I'm standing by to hear outrage from the CF enviro police and the fuel filter police

In my boat that would possibly be an issue as the diesel fill is on the cockpit sole...
On many boats with deck fills i doubt it would be a problem...talking small percentage of 'petrol' in the diesel.

In the mid 80's the end of the fueling jetty at Williamstown, Vic was destroyed together with the refueling powerboat when someone pressed the flush button in the head while fueling.
