>>>>>>>> Return lines are a wear item, they don't last forever. I had to replace them on my cars before ULSD came out and I haven't seen any rise in the incidence of them needing to be replaced since. I think the change to ULSD was much ado about nothing, I didn't notice any change in how my car ran or anything else after the change. Pretty much the same with ethanol, that one is something I'd rather be without but I don't see it as big a problem as some people do. When we first switched I had a little trouble on the snowmobiles but once I quit using Sta-bil and switched to Seafoam for my gas additive the problems I'd been having went away entirely. The only time I have trouble now is if I forget to add Seafoam so I add it to every gallon of gas I buy at the time of purchase. >>>>>>>> Curt Well, I've seen the change on my old 617s, not sure what cars you are looking at. I've had my 617s for around 18 years. I replaced the return lines after ULSD became in general use and I haven't replaced them since. Thus, I attribute it to ULSD and not them being a wear item, which they might be, but again, not in my case. As to the ethanol, my 5.9 Dodge Ram gets about 2 mpg better mileage on gas without ethanol (when I can still find it out in the country) and it also runs smoother. Smaller or different engines might react differently, I can only vouch for how it affects my Dodge. I guess we can all have differing experiences...that's what makes the world interesting.
