During my Valve adjust today I noticed that my #5 injector return line is just staring to leak. Since I will be running B100 very soon(80 gallon batch curing as I type) I want to put viton on there and be done with it.

Does anyone know what the Inside diameter of the return lines between the injectors is? Also I noticed the ones on there dont use a clamp. If a hose material other than stock is used is a clamp required?

Thanks,
Stephen
