Replacing the fuel lines under the cowling of 40hp Yamaha

I hate to start another thread just for this. But you guys have been so much help with this project.
1992 40hp Yamaha. I now need to replace the fuel lines under the cowling. I have tygon hose here from other things I’ve worked on. Would it be ok to use it or should I order the OEM parts. I don’t want to do anything dangerous trying to save a buck. It’s not worth it. Any input is greatly appreciated as usual.

Update...... I’m going to order the OEM so I have no worries. I’m a big believer in preventative maintenance. Doesn’t do any good if I do it wrong.

best thing ive read on a forum.

Okay I received the hoses I ordered for under the cowling. I have one more question. I’ve replaced all the fuel line and fittings from tank to motor. Also installed a 10 micron water separator. There’s a clear in line screen filter under the cowling that’s not oem. Should I keep it when replacing the line or am I good with the water separator? I don’t know that the fuel pump has a screen. I know it originally came with an inline filter from Yamaha. My concern is will I have a problem with fuel restriction. My new line from tank to motor is 5/16”. Them 1/4” (6mm) under the cowling.
