18’ Hewes Fuel line replacement

[Shallowminded6]

When I spoke with international marine about purchasing an engine. They suggested I replace my fuel lines prior to the install. I have a 2000 18’ light tackle. So I believe it to be the same as the CAD 18’ redfisher. My thoughts so far is splice a new line with the old at the fill side and pull it to the stern. Any input or experience is much appreciated.

I would pull two chaser lines through when removing the old tubing instead of pulling the new tubing through.  If something were to come apart between the new and old tubing, you would be done.  Pulling two chaser lines means you use one of them to pull the new tubing through and still have a backup if something goes awry...and, if you get to needing the backup, you could use the backup to pull two more through so you always leave yourself with a plan "B".

As Jake pointed out having an extra chase is never a bad thing.  

I replace the lines on my last Hews as you explained.  I simply connected the new line to the old via plastic hose barb and pulled the new one through.  Easy and simple, i had no hang ups.

Thank you for the input. Good points. I think Im going to try a hybrid of the two. Hook the new line to the old one and attach the pull strings. Anyone have insight on fuel lines to use or steer clear of?

I also noticed my fuel line is zip tied to my stringer on the starboard side. Did you leave yours laying on the tank/bottom of the hull or put it in conduit or some sort of protective sheath?
