Converting my 1965 type 2 motor to full a flow remote filter system. Do I stick with the standard 21ml pump or get a 26ml one.its in a farm runaround rig which I built. So it won't be doing any high speeds.

No larger than 26

Thanks Chris.gene berg had some good info on pumps etc. He said the 26ml one is more than enough for a stock or mild engine.

Yep. I run a 26mm Schadek pump on my 1904. Never had a problem. Oil pressure is spot on. Case is tapped and plugged so it has a single outlet cover.

we[[ I went for a 21ml plugged shadek from from aircooled .net. being an all purpose tray back farm rig which will hardly ever go past 80ks anhour, it should do the trick,
