New to the forum here. I purchased a 1972 240z from a member here.

I want to replace the carb bowl to nozzle hoses. Does it matter what type of fuel hose I use? I saw this link and was wondering if it had to be thin or special type hose. SU CARB BOWL TO NOZZLE HOSE

To work right it has to be a special flexible pre-molded hose, otherwise it'll side load the nozzle and interfere with the choke returning.

Last I checked ZTherapy stocks them, probably other folks too.

I've never tried anything aftermarket but the problem probably lies in the stiffness & possibly the diameter. The stiffness would likely bind up the nozzles when the choke is used and cause them to stick and eventually wear. My only source for them has been Ztherapy. Go for the good ones. One less thing to worry about.

I've seen fuel grade hoses of different sizes at Home Depots lawn mower parts section... may work in a pinch

I bought new hoses from ZT and they were really soft. I ended up swapping them for clear hoses that came with my Mity-Vac vacuum pump kit. That way, I could see if I didn't have any fuel going to the carbs from the bowls.
