The stock pump will move WVO just fine, but using it makes a MUCH more complicated conversion than is necessary. We prefer to delete the stock pump and filter because it cleans up the engine by removing a bunch of hard to get to parts that can be problematic (fuel leaks). Using (2) electric pumps and simple one-way valves makes a very simple and durable conversion with the added bonus of redundancy. Many of us have been able to drive home on 'the other fuel' after having an issue with one of the fuel systems!

Here's the last OBS truck I did a conversion on:
