have had a plastic one for about 10 years,dont know brand,but works well. I think its either a tempo or moeller. one thing I did was put a pressure gauge and a valve stem in the tank. I put the stem in the filler cap and gauge in another cap on top. if you pressurize it with 5 psi=now you can pump uphill. works great if you have air nearby,like at my shop.it still gravity feeds the same
That's a great idea with the valve stem and pressure gauge. I have a 15 gal. Gravity feed seems to take forever to fill the sled.
