New Fuel Lines Without Removing Fuel Tank

I just finished putting all new fuel lines in our FT without removing the fuel tank.  Originally we (me and my friend Fred) had planned to remove the tank but it didn't appear to be easy so we merely cut the push-lock fittings off one end of the old hoses and installed them on one end of the new hoses, coupled the fittings together and pulled the new stuff through.  The hardest spots to pull through were where the Great Stuff foam seals each end of the raceway, but with a little foam removal they slid right through.

We could not get the fiberglass tank covers out through the bay doors without cutting about 3/8" off their tops with a whiz-wheel and belt sanding the cut smooth.  All the original push-lock fittings were reused with no leaks, and I did have to remove some slight razor blade scores that happened when I cut the old hoses off, but that only required a little filing and sandpapering.

Total cost was about $300.00 using all Parker Push-Lok hose.

Not having to remove the fuel tank was a Godsent I think.

Been running that hose for a few years. No issues.
Good job dude

P.S. I didn't find removing the tank any big deal. But if you did it with out, awesome.

T man, trying to really understand what you did with the tank end. Did you leave a piece of the old hoses on that are connected to tank then splice into them ( a short piece of old line)?
If so I was under the impression that most cracks in lines are at the ends of them rather than along the rest of line.
Maybe I am just waking up and do not read your comment correctly, can you explain?
Thanks

John,

I connected the new hoses onto the old ones and pulled them through, one at a time.

For illustrative purposes;  I cut the fitting off the 5/8" fuel line at the primary filter,
then attached that fitting to the new hose. Then using a male coupler I attached the new hose fitting to the old hose fitting that was originally attached to the fuel tank and just pulled the old hose toward the engine, replacing it with the new hose.

All the hoses have been replaced in their entirety, using all the original fittings.

I did mine like this too.  Spent about $6.00 on a brass union and pulled new one through from tank back to engine.  Once I had all parts in went in real quick.  Just needed a tiny mexican  to lay up on propane tank to fasten new ends to tank.

Glad it worked out for you. I  didn't find pulling the tank was a problem or particularly hard, but mine was pretty much empty anyway.

Look for small cracks at the fuel line fittings.  The lines closest to the engine are most vulnerable.  You decide.
