BK,

I had to google SETRA, I thought it was one of those European cab-over tractors!!

Oh that was a good laugh!
first 3 from the left are Setra's!

Stop when the nozzle first shuts off automatically and it will probably be as accurate as any other method.

This is what he stated nothing to do with foaming.

BK,

That's quite a fleetl.....very impressive.

BK, I guess Setras don't have foam

Nice fleet!

I would guess that the fuel foams after passing through the restriction of the valve

i used to be hit or miss with foaming at different stations, but nowadays seems seems all i get is foam. could it be the cheaper stations.

Thank you and I have to be honest the dark blue MCI is not actually part of the fleet any more as it sold shortly after these photos were taken!

Thanks also, and I don't have a clue why but I don't recall ever having foam or at least not much of it when fueling a Setra! Which really in a way surprises me as the tanks on a Setra are like 4' Tall X 2' wide and there are two of them side by side connected at the bottom by about a 1.5" hose and the go all the way across the bus behind the steer axle minus about 3-4"s in the middle! (these measurements are not exact by the way as I have never had one out of the bus! But Paul Hastings has and posted pics here on the board on a post about "help someone put a hole Thur my fuel tank" or something like that! FWIW!) I'd think as deep as the tanks are if it were going to foam that fuel falling that far into the tank would foam worse, but who knows!

NOT that it makes any sense or even matters.....

Maybe has anyone thought about "Air Injection" at the gas/diesel pump?

Air injection increases the volume of the liquid as it is being pumped before it is measured with the "volumetric" sensors that run the display...

You won't get anyone to admit that they do that. BUT... They do.

That extra 2 to 20% reduction in actual liquid racks up lots of FREE MONEY
to the station operators.

Yes, You are Paying for AIR... It's a RipOFF... Tried and True...

Or, When is 10 gallons not actually 10 gallons.. ( If it comes out the hose foamy! )

...

Ohh... I should shut up now.. The secret is out...

I think BK has a point. His Setras don't foam because of the design of the piping and tank. I was using a American Eagle with a two side fill and it foamed so much I would have paid somebody to fuel the thing. you had to drip the D into the thing. I don't agree that the problem is associated with a "new blend" but that may be a factor. Every edge that the fuel travels over would tend to create turbulence that would contribute to foaming. Maybe a tank manufacturer or Setra Hisself could add something to this.

Our DL3 foams very little. It has a one side fill, passenger side, and it seems to do well. We have also taken the bus all over, so I don't think that it not foaming just has to do with our one station that we use to fill in town.

FWIW

God bless,
