How come gas nozzles always leak a bunch of fuel out of the nozzle?

[The motor guy]

I swear most of these pumps dribble fuel out slowly when not in use. I'm pretty I just dumped like 3oz of diesel fuel on my shoes.

No dribbling problems here.

That's a high volume station I go to. Maybe they're just worn out. The diesel pumps always do it regardless of the station, gasoline not nearly as bad, but even the gas pumps drip out a ton of gas as soon as you turn the nozzle toward the ground

When you pull the nozzle out of the filler hole, do you rip it out quickly and do you let it aim down or do you remove it gently and tip it upward? Consider gravity. You have to tip the nozzle upward to put the nozzle back on its cradle anyway.

There's more than one hose inside the hose-- you've got a little one that's running suction for the vapor return. I suspect that's the dribbler.

When I drove & filled a diesel daily, I ALWAYS pushed the little door/switch to make the pump stop, then pulled the handle & spun the handle upside-down (or at least sideways) to drain it. If you do that, it never leaks A DROP. Got some funny looks & comments from c-store clerks, but NO diesel on the work boots.

I usually give it a shake, especially when I fill the diesel. But not too many shakes.

Sure but if you keep the nozzle up while pulling out nothing can dribble out once the nozzle comes out of the filler hole. It's like when drinking from a bottle. If you don't tip the bottle upward before pulling away from your lower lip you will spill the drink on your chin, shirt, crotch, and shoes. You guys do know how to drink beer from a bottle, I presume?

You don't want me to witness that. I'd have to make an unsolicited remark. Maybe dabbing the nozzle with a paper towel would be more appropriate. I think I'll take a picture of proper, dribble-free nozzle extraction for the benefit of the driving world.

I usually lift the hose up above the level of the dispenser before removing it. This gets any fuel at the bottom of the hose bend drained into the tank.

More than three and you're just playing with it!

Diesel probably doesn't have a vapor return. Most places do not have a vapor return. Just one hose. This area still has stations that do not return vapor to the tanker truck.


There is the whole trip mechanism for the automatic shutoff that can hold fuel and let it dribble. Diesel clings more than gas so it dribbles more.

IDK. The older they get the more they dribble too it seems.

When you get old some times no matter how many times we shake it it is never enough.

 

[The motor guy]

They don't do they ridiculous vapor recovery anymore. They got rid of those corrugated rubber nozzles.

 

[The motor guy]

Maybe it's just from people who yank the nozzle out keeping it up right and hang out back onto the pump holder. Personally, I like to make sure some little kid didn't put their skittles inside the pump nozzle, so I let drain out whatever is inside. Or they put it in the Def tank by accident and that's Def fluid coming out.

The problem is when I first start pumping is when it dribbles. So, when I remove the nozzle from the pump and select whatever grade of fuel I need. I always let it finish dribbling into the tank once I'm done pumping. My only guess is most people don't do this and I get a slug of gas still in the nozzle because they yank it out of the filler hole and hang it up..me being cheap I want to get every last drop I paid for.
