Which fuel line would you recommend?

I have a 12v fuel pump (approved for gasoline use) and I want to use tubing so I don't have to lift 5-gal cans up to the tractor. Also, when I'm busy elsewhere, wife can't lift the gas cans to refill the riding mower.

I have a choice of 5/16" PVC fuel line (clear), or 5/16" polyurethane fuel line (blue). This will be used year round, so has to handle extreme cold. 50 feet of each is about the same price.

Which would you recommend, and why?

If your trying to transfer gas to tractors you need to get a, Approved 12Volt transfer pump and approved hose.

Using a pump with 5/16 line will take forever and probably a few pumps.
Even if you use 3/8 line, would be better but not much.

Whatever line you use pvc or whatever, make sure it's rated for gas, and the piece that you submerge in the tank is rated to be submerged.
Some will melt.

Make sure you use something that doesn't build up static electricity with gas flowing through it.

the blue line should be fuel rated , the other I believe gets hard with gas

They make 1 gal cans and be a lot easier and faster than a small pump.

Does the fuel pump have a very small output port that you can"t use a normal 3/4 or 1 inch rubber/neoprene gas hose?

I agree, by the time she figures out hooking up that setup , plus the risk of an explosion, with a 1 or 2 gal can she will be on her way.

Looking at the chemical resistance chart, both have a C rating, meaning marginal. All I found was for gasoline, not E10. Ethanol is what attacks tubing, and I would expect a shortened life unless it can be completely drained when done.

Something that would be more compatible would be automotive neoprene fuel line rated for fuel injection. It's good stuff, holds up better than anything I have found.

But, I have a real concern about static discharge, and making/breaking the battery connection.

Fuel transfer hose has a ground wire woven into the cover. You could add a ground wire clamp from the pump to the container being filled.

But the electrical connection...

Most use alligator clips or a cigarette lighter plug. Chances are you could use either one with little chance of a problem, as long as everything was going right.

It's when someone else uses it that's not familiar with the dangers, or the tank overflows, or the cord gets tripped over...

I think I would lean toward more manageable size containers or a hand pump.

Thanks for the input. Rather than switching to smaller cans, am going with the fuel pump. Why? Simple -- that's what fits our needs. I have to manually transfer gas to my Dodge plow truck in winter, the riding mower, push mower, Farmall, etc during rest of year. I have tried changing out cans, but there are times when it's almost unbearable in the cold and wind, or when skeeters are horribly bad, not to mention inevitable spillage now and then.

So, here's what I have in mind. I ordered (2) of these fuel pumps:
https://www.amazon.com/gp/product/B07JPDZC4M/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

Will use (1) pump most of the time. Only plan to use both pumps together when filling the Dodge or the tractor, which have tanks that will easily hold a full 5-gal can. With the smaller engines come smaller tanks, so just one pump will work fine for us.

Will make a "filling station" for the pumps. They will be mounted on a metal post that goes into the ground. Using metal for the reason mentioned, to allow any static to escape to ground. Will also have a thin copper wire wrapped around part of the hose(s) that will wrap around the fuel line both input and output sides, plus over the pump(s). That should ensure proper grounding.

When needed, will connect the pump(s) to a small 12v battery. Once connected to battery, will have to flip a switch to start each pump. And yes, I have a fail-safe to prevent any confusion about which hose/pump is being used, and which switch to turn on/off.

Same as at gas station, will be standing right there the entire time. Gas cans will be stored a short distance away, sealed as always. Hose ends will be protected against bugs or contamination getting into lines.

Heck, just typing all this out is more complicated than what I have in mind. Also, the Dodge (for example) is difficult to fill using "any" gas can. Always have to use a long neck funnel, which means lifting the gas cans higher in the air.

Anyway, not looking as to whether I'll do this or not -- the decision has been made. I was asking about what type of line might be best. See, I ordered the polyurethane fuel line:
https://www.amazon.com/gp/product/B0045LE5CE/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

What I got was PVC fuel line. Says right on it, "50' SPI 5/16" CLR PVC FUEL LINE". The two lines appear to be similarly priced. I wanted polyurethane because I thought it would be more flexible in cold weather, plus I didn't realize that there was even such a thing as PVC fuel line. So, that's why I asked.

Steve your right about static I hauled fuel in tanker for 5 years , we were never allowed to have a plastic bucket to catch drips , one day a mechanic form a different company was carrying 5 gals of gas in a white plastic bucket it rubbed on his polyester coveralls and caught fire he then panicked and through the pale and it bounce back and cover him in gas on fire, all I know he lived , but was severely burnt

Neither one is an option get the neoprene rubber hose for fuel. Also the gallon jug would be faster and easier than a pump ,for the lawn mower.

Well, KCM, all that sure wouldn't fit my needs, LOL. For over twenty years I have been setting the 5 gal bucket on the hood and siphoning it in with one of those $2.99 transfer siphons from the hardware store. I guess I don't have the free time that you do, LOL

Use a hose rated for gasoline transfer. It will have a
metal wire running the entire length to discharge
any static electricity.

For smaller diameter tubing such as 5/16 or 3/8 Tygon tubing is a excellent choice.

I get my gas and diesel in 2 1/2 gallon oil jugs, have done so for years. Easy fill, easy lift. And delightfully low-tech.

I could not handle a 5 gallon can so my cans were 2 gallon for the tractor or 1 gallon for the mower. So much easier to handle and with that you could tell when getting full to stop. what you are planning you would need a pump shut off switch at end of hose so you would not run tank over when it got filled and that switch could be a good place to get spark and boom. Have not read all posts to see answers so don't know if anybody though about that. But get the small cans and forget that fuel pump.
