67 coupe, fuel lines are the old iron type, probably original, i was wondering if i could change out the old metal lines with nylon hose or the reinforced
rubber hose, ( i seem to have alot of that already in the car in various places already ) but it looks alot like small dia raditor hose.

could i just clamp off the tank feed and pull the old line out and replace it
with new flex hose or something ? change the tank ?
also does anyone know if there are screw in type gas cap conversions ?
my 67 has the old fashioned twist lock type but it doesnt seem to be very tight, i swear i loose gas just through evaporation...lol

any info would be appreciated,

hiya, replace them like for like. wouldn't use any nylon or other things. I believe you have rather rust and crap in the tank than in the fuel lines themselves. if the fuel lines are good on the outside (no kinks, etc) then there might not even be a need for replacement. Check the gastank first.

 

will do and thanks, gas tank looks to be fairly new thats why i didnt consider it
first, and the old hard lines looks all rusted up, maybe just dirty ? i dont know
but all that crap in my old filter had to come form somewhere.
and i thought gas tanks werent supposed to rust LOL.
ty again !

 

These gas tanks do rust, a lot after 43 years! you can actually get treatment systems to pretty much "seal" the inside of an old tank, but they are messy and a new tank isn't too pricey. As for your lines, you can order pre-bent lines from pretty much any of the major distributors for about 30-40 bucks I think. They even offer stainless as I recall for not much more coin. Easy to install in less than an hour.

 

Yeah you need to get the tank cleaned and sealed or replaced.And replace all the fuel lines if ones got rust in it they all will no use patching it.Bringing a old car back to life isn't cheap or easy but in the end its worth it.

 

How long have you had the car? Maybe the PO replaced the tank, but didn't change the fuel filter? If the tank is in question you should probably pull the fuel sender and check it out. You might be surprised by what you see inside!

 

FYI...my lines looked ok concidering they were 43 years old. When I was restoring my coupe I was replacing everything. I started to pull the line and it just cracked wide open. Some of the spots that looked like light surface rust had about .00001mm of pipe wall left yikes.

My advise, yank the lines to be safe. Its not a huge deal and you will have the piece of mind that its done and safe.

You can just run rubber lines front to back if you wish. Just be sure to secure them with rubber clamps to protect them.

 

Also keep rubber lines FAR away from the exhaust, for obvious reasons...

 

I have seen gas tanks that looked great on the outside and were a mess on the inside.
