Hello all, found this great forum awhile back and love it! First time posting a question, so here it is. I own 3 2005 f-350's,all are crew cabs, dual rear wheels with utility beds. Been reading a lot about regulated returns for the fuel system. The theory behind them makes a lot of sense but, would it be beneficial to install them on bone-stock trucks? My trucks always have a load on them and are usually pulling a trailer of some sort. Mostly highway driving. Just wondering if they would be worth the investment in my situation. If so, where do you guys recommend purchasing said regulated returns? Thanks in advance for any advice.....
