diesel pumps vs. gas pumps question... - Sun Sep 10 2017 06:30 AM

did diesel pumps have a larger diameter hose and/or nozzle than gasoline pumps had?

i picked up a nice, N.O.S. brass nozzle, cheap, that was apparently meant for a diesel pump, and the inside diameter of the fitting is slightly larger than one and a half inches. i don't have a hose on my M & S 80, but i assume a one inch hose would not fit(?)
if not, is there a reducer fitting available to marry these two sizes together? i can do the research on the fitting, but i thought i'd ask while i'm asking my other question.
if not, i think i will be posting a nice, N.O.S. brass nozzle, cheap, in the classifieds section, ha aha.

thank you in advance,
tred

ok, so, apparently i like to leap before i look.
there IS a reducer fitting on my nozzle which is what makes it a diesel nozzle, it would allow an inch and a half hose fit into a nozzle which is meant for a one inch hose.
i removed that, it's a two-piece which i have NO idea how it would come apart, nor do i need to know. i simply removed it from the nozzle and now the same hose that fits into the outlet on the pump fits into my nozzle.
does anyone need this fitting? it's chrome like the standard fittings but then the larger, lower portion of it is brass.
FREE to a good home.

i find that odd, that this is really the only difference between diesel and gasoline. haven't researched it yet.
diesel flowing through an inch and a half hose would bottle neck when it hit the nozzle itself, so why bother?
anyone?...

Not all diesel pumps had the 1 inch fittings and some gasoline pumps used the one inch fittings. Some nozzles have a larger spout so there would be a faster flow.

As Matt described, there is no set rule.

Quite a no.of years ago when diesel started showing up in service stations some used LARGER nozzles that would not fit into a cars GAS fill pipe,you would be surprised at the amount of drivers that mistakenly put diesel in their gas tank! Saw it first hand!

I have a 80 gallon tank in the bed of my diesel pickup. It and the factory tank will hold 110 gallon. So I go to the truck stops which has the large hose and nozzle for tractors trailers.
You don't find the big nozzle at the car bays.You have to knock out the flapper valve in the stock tank or it won't fit. Had a friend who put diesel in his motorcycle that didn't work well,but it was really clean when we torn it down.

Putting diesel in a gas vehicle isn't good thing but on the other hand it isn't bad. Putting gas in a diesel vehicle is a bad thing, no doubt about it.

Are you suggesting that gasoline engines run well on diesel?

No,not today's modern computer controlled ones. Actually the computer might make enough changes that they might run pretty good. Diesel engines will run off kerosene or diesel and so will jet engines. I've had old tractors that you start on gas and after they warm up you turn off the gas and turn on the kerosene and they run good on it. When we were kids in early 50's and didn't have much money and gas was .25 gal and kerosene was .10 we would put kerosene in our old cars and they run well but smoked some. Next day when engine was cold you had to rig up a gas can direct to car. to get it started.
what I suggested was if you put diesel in a gas engine you will have problems but not harm the engine but if you put gas in a diesel engine you may blow up the engine.

Maybe I'll get you back on track. I can't speak to back in the day but from 1999 most truck stops in TN. use bigger nozzle and hose for the semis. I can fill the pickup I spoke about in 1st post in half the time as opposed to using diesel pump at car pumps.
Now you walk around the corner to the car pumps and they are using the same pumps. Can't speak to computers and pumps different in pumps that look just alike. Maybe the pump guys can help with that.
