Grey line change out, Need to change vent hoses too?

[77Eltigre]

Basically title, I have a 94, thats entirely original, ran good at the end of last summer, but I have the time so I'm going to change the hoses out and hope I get away from having to do a carb rebuild.

My question is: is there any benefit to changing out the grey hoses that are the vent lines?


Also the pressure relief valve on the port side (left side) is that just a friction fit? or is there a method to remove it and install a new one?

Thanks

They are probably good, I would do an internal inspection, as much as you can, on them. Look for deterioration. They have been on there a while and and I don't think they are rated for 20plus years of service. If they look good you can keep them. Don't forget to check your vent valves for good operation.

But..... I personally would change them out. Its easy while you are in there and have all that new hose laying around.

Yeah just change out the supply and return line no need to change the vent lines

I would replace them because the vapors do the same thing as the gas and it ends up clogging the check valves. I had this problem and didn't even realize it. It's not much more line depending on your machine. Also for the check valve/pressure release, you need to just pull it out maybe wiggle in a little, or push it from the outside if it's not budging
