I have 5 of these red VP jugs and put 6 gallons in each. They are heavy to lift and pour, I laid it on the wing with the spout in the filler neck. I made some filler necks with a shut off valve and a 90 degree elbow. The vinyl hoses get stiff over time. I converted my engine from 150 to 160 hp recently and since we can't get high octane ethanol free car gas I have been using the airport fuel pump and 100 LL until the airport manager ran out of fuel for the 3rd time a few weeks ago.
