Hi-Flow Diesel and 4WD's

I use them all the time, no issues at all.

Presume you mean the hi flow pumps at servos? If you do, no problem at all, most still have the auto mechanism intact, makes filling a long range tank easy. Cheers.

My Colorado doesn't like them. It likes to drink slowly and savour the flavour.

Possibly the diameter or shape of the filler neck, but it just tries to gush out unless the handle is only part open, which defeats the purpose of the high flow pump.

Anyway I am a patient man (sometimes) and the Colorado only takes a moderate amount to fill the tank.

They are a tight fit for our 100 series and make mostly foam. We don't use them.

What damage would you be expecting from them? I'm pretty sure they are there more for LR and maybe some HR trucks with bigger tanks so the guys aren't standing there for half an hour filling up.

Fits Disco OK but not X5. Some towns don't have "car" nozzle at all (eg Urana) which adds to trip planning.

Some of the bigger "service" stations here in Victoria have Trucks Only signs up on the high flow lanes, needless to say, I no longer patronise them so I fill my 180 litres elsewhere.

Benno,
There's one way to find if your vehicle can take a hiflo pump, stick the nozzle into your tank filler and pull the trigger If you don't get a shower of diesel it's ok to use the hiflo pump.

Cheers

Disco.

No issues with my 200. I actually avoid normal size bowser's in I can as they take flaming ages to fill up!!! I've actually boycotted the local Peak station I used to use as they have started a policy of trucks only at the hi-flow bowsers. Apparently truckies have been complaining that 4WD's take to long and hold them up!!! What a joke. Surely sitting behind a 4WD would be quicker than behind another truck??? I'd been in situations where the 4 hi-flows were empty and I'd be waiting by the car bowsers for ages. On questioning their policy they refused to budge so now I go to the local Shell Station instead.

I had a discussion with a servo operator once who blanket refused to let me use the high flow as he said "you 4wd'ers make too much mess using the pumps so you have to use the standard pump" I promptly drove off and he lost about 250L of fuel (I carry 273L)

he doesn't work there anymore so go there again - without making a mess

cheers

I have problems with them. My primary tank on the 40 can take a high flow, albeit with a bit of blow-back, however my secondary 110 liter slave tank has immediate blow-back and causes the pump cut-off to activate immediately. The only way I can use a high flow is to try and hold the lever 1/3 open - a major PITA to hold the lever half open for 10 mins....

Basically, if I can't see a low flow ... I drive on.

The best thing invented for re-filling a 200 series Turbo Diesel you can pump in 130 litres in minutes or under what it takes to fill a 65 litre petrol car.

On my recent trip I used the High Flow as often as I could.
One thing I noticed, which was mentioned here a few months back.
Some places have a cheaper price for High flow, than Low Flow.
usually only a couple of cents, but one place in Queensland (for the life of me I can't remember which town) was actually 10cents cheaper.

Benno,
I wasn't going to answer this thread but it has strayed a bit on why servos ban 4wds from the quick fill pumps.

To start with the hi-flow won't hurt anything if you use it but as said you may or may not get a nasty surprise when you get blow back because the breather and piping can't cope.

THe hi-flow pumps were only ever meant for trucks because of the tank capacities. Now Fred, George and Harry line up in front of a truck or three. Fred fills but the missus wants some bread and a few lollies for the kids so more time is lost as Fred finally comes back and shifts his vehicle. So it goes on until the first truck finally gets to fill. Remember if the wheels aren't turning he isn't making money.

Now the truck stop servos would rather have a happy customer taking on 1000 litres, than him waiting for another another customer taking on 100 litres.

Maybe all transport should go to the Banlaw quick fills and that will stop the problem immediately. Now boy can they fill a tank quickly. They come in sizes that will flow from around 40 to 1000 litres/minute. Small ones flow around 300 litres/minute.

If we are going to move off topic a bit then lets go a bit further. We all know there is a discrepancy when it comes to indicated fuel pumped, and whats actually gone in the tank. Surely there would be a larger variance with Hi Flow as more fuel is being passed at a faster rate. Or I could be wrong.....

Use the Hi-flow if the van is on the back 14.5m all up is always easier to get in and out of servo.
Nissan D40 will take it at full flow.

cheers Phil.

Common sence would come in handy here again.
If there are trucks around, especially if waiting in line, don't use them. If it is quiet and your about the only one there, why not?
