Awesome.....That was the best info.It is definately plumbed correctly.I just finished hooking up everything and installing the new sender unit.The vent was 5/8 hose barb welded to tank and forward.I had a 1 1/2" od stainless u turn made so I could avaoid the kink that was in the original fill line.I am linking to some pictures so you all can see how it ended up.Thank you again for the quick answers....Its assuring to know that it is exactly the way its suposed to be.I could not get to the back of the original bow vent so now theres two..oh well better than another pie plate access and it was in a impossible to get to location.well now its time to scrape of the sealant and fill in the old holes on the deck so I can get everything back together.Cant wait to fill her up regular style!
