Should have added no leaks either. I wasn't sure if the raiator, or tranny may develop leaks, not to mention the fuel system! Took a while to put in my fuel assending unit, which delayed the overall startup by a few hours. One of the bolts that holds the assending unit down broke off while bolting it on, so I had to drill it out, used a screw extractor, but just ate the whole thing vs. backing it out. Will have to put a helicoil or tap to a bigger thread size for that hole, but not a huge deal. I was relieved no gas leaked out when I filled it.
