Review on 4Pcs Fuel Line Connector 800 191 by Eric Temple

I used these connectors to connect two lengths of nylon fuel line. Pipes coming out of the gas tank from the fuel pump and new nylon pipes that replaced my rusty/rusty metal fuel lines. There wasn't much clearance and I couldn't use a heat gun to heat the line next to the gas tank, but I was able to get these fittings onto the line after installing the fitting and the end of the new nylon line in very hot water for a while . a few minutes. Without heating up the new nylon cord and these connectors, I was unable to connect the cords. However, I didn't need to heat the nylon line coming out of the gas tank's fuel pump.
