Hello, all -

I'm going to replace the oil lines and fittings to the 235's oil filter. I believe the fittings are 1/8" NPT. How should I prep the fittings at the motor? I'm guessing I don't use PTFE tape. And, I'm assuming they don't go in naked.

If I were to get these lines pre-assembled, does anyone have a good source? Doing a "quick" search, I've only found them at American Classic Truck Parts for something like $35 a set.

Thanks!
