I used regular tape in both ends. The sand doesn't want to come out once you get it in. I had to blow them empty with pressurized air, it took a suprisingly high pressure but when the sand started moving it was a projectile weapon.

My bender is about the same as in your first picture. Seemed to work fine with sand-filled tube. The tube seems to harden after bending, so you either get it right the first time or try again with a new piece.

Here's the tube I used:
Speedy Metals SKU: t4r.625x.035-72
5/8" OD {A} x 0.555" ID {B} x .035" {C} Wall Tube 304 Stainless Steel, Annealed-72", 4 x 72", subtotal $82.12

Tuomo - thats the tube that works well. I was trying the .028 and have the problems. The .035 is really tough to bend multi-angle.

Well, then there you go. I did not see this originally. They even have the dimensions for the fittings. You can order specific pieces with the ends put on too. This stuff is (way) cheaper, but not as flexible as:

I'll have to see if I can get away with having them make some difficult fittings.

if it's going on a road car, The Aeroquip hose is industrial build. Many years of it working in any
number of aplications.
Take your time- plenty of choices of ends & adapters- has to be something that will work

Hey -

I wanted to update this thread. I had some more short lengths of .028 SS seamless, and I decided to try bending another piece for the section from the transfer pump up and back to the entry on the back of the swirl tank. I filled the tube with flour, as I did not have sand and felt that could get nasty. It took 15 minutes to fill the tube properly and pack it in, but then I tape over the ends with Duct Tape, and bent it with the larger bender with the outside die....

It Worked! A nice, 90 degree bend and smaller 25 degree bend in a different direction. A minute amount rippling on the inside, but barely there.

Thanks for the medium-filling mandrel idea. I have another stretch from the pressure pump to the final fuel filter before the run to the front of the car, and the hard line stuff will be done basically, unless I use some hardline for the manual transmission cooler lines.

Frozen soapy water. The TV showed me trombone pipes being bent with it.

Try clean, dry glass bead media, it is very easy to work with, fills easy and comes out easy and clean.
The same kind you use in a bead blaster, i get mine from snap-on.
