The only difference between a 4BT and a 6BT is the back 2 cylinders are cut off, so most parts are interchangeable. Since your 4BT has a diaphragm LP you must have a VE IP?
You can use the low pressure piston pump but might want to regulate it so you don't blow the IP seals out. I would suggest using the stock pump and put a fuel pressure gauge on it, along with a new filter and see what your pressure is. I would say the LP should be between 3-5 psi. I was reading on a Mercedes diesel site about people using WVO and they suggested a Facet Posi-flo 60301 electric pump it held up good with the WVO.
