bending fuel oil line
How do you bend coated fuel line? so far I gotten away with bending around a piece of pipe or a can etc. So I figured I would up my game and picked up a Kline roll bender "Klein-Tools-51006-3-in-1-Tubing-Bender"
The plastic gets beat up a bit and it just one radius.

the groove needs to match the od of the tubing and coating. there are also internal and external bending springs. how many radii do you need? you just bend it until you get the angle of the new direction that you need.

Fill the tubing with sand. Then clear out the sand after the bend is completed.
R-22 works good for blowing out fuel lines. Oops did I say that out loud?

After you make that expensive repair and you still have the same problem, What will you check next?

That's the kind of bender I use on small tubing. If you are having scuffing, try spraying the tubing with silicone spray before bending. Make sure the silicone spray is suitable for rubber and plastics, not all are.

Unless you need a tight 90, bend it by hand, working it up and down the bend a little. Otherwise use the size bender for the outside diameter of the tubing with the jacket.

"the groove needs to match the od of the tubing and coating." yes, but who makes this?

refrigeration 1/2”.
plenty of electrical lubeTry not to slide the tool but walk it.

a little bit bigger is probably ok. a little small is going to tear up the plastic which its probably just a cosmetic issue.

you can also fill the part you want to bend with water and freeze it. it won't burst if it is a short section. both have issues with getting the line clean enough for fuel afterword.
and you won't need a second mortgage for the r22 like Ed's method.

I can't see using a bender on contained oil line ? A boot works in the corners ..
For bright work I like ratchet type , looks like a cross bow . You would need try the larger size

I use the 1/2" block to bend 3/8" coated oil line. I have this mostly for refrigerant piping.
While I was looking for a pic of that one, a came across this.
This was on the HD website.

I have that set @HVACNUT but the bending forms are all black plastic like the clamp die. I like your pretty colors!

I know REMS , and maybe the other German benders have metric sized heads available. Measure the OD and see how it converts to metric sized

Its only 3/8" I would just bend it by hand.

This one works fine for soft copper. I use the 1/2 for 3/8 jacketed, when I need a tight 90.

do you need cotton gloves to use it?

Can't get hands dirty.

i watched a video of someone using foam in a can without gloves the other day. there are lots of things that i don't wear gloves for and lot of other things i sometimes wear gloves for because it is easier than scrubbing my hands in gojo or paint thinner but latex or nitryl gloves are great for foam in a can because more or less nothing takes that stuff off.

I did that once :) Even with gloves you get it on you, and spending the day peeling it off .

I like Rectorseal "True Blue" pipe dope. It works good to prevent leaks. Not so good it's tough to get it off your hands and gets on the tools as well.

Before latex gloves became fashionable it took a two week vacation to get your hands cleaned ..

And all your callouses went away so you went back to work with raw hands.
