I don't know if you have found your green hose yet or not, but this evening I stopped to fill up with gas and noticed my local station had just gotten some new hoses on the diesel pumps. The hose had the name Irpco on it, their web site is (irpco.net). Hope this helps.
Thanks... yes I did... I seen my Sinclair station had them on their diesel pump and asked. After a few long distant calls got one from Denver. Got the last one in this area I guess... green isnt popular with stations here I guess. It's 5/8 hose but really cant tell much of a difference. Thanks all for helping me out with leads and ideas.
