Other alternatives are power steering pumps,
The Fall Season 1 & Season 2 Boxset DVD, furnace pumps,
Sons of Anarchy Seasons 1-7 DVD Box Set, and automotive fuel pumps. Do not skimp out and buy the other Shurflo pumps which look the same but are cheaper. The valves and seals in the pumps will not work with petroleum based products and I can not guarantee that you will have much luck with them.
