power it trough a small brushed esc for example.
The pump has a silicone seal/diagram - Would not like gasoline - But as Bert pointed out I think it would deliver too much.

Thanks about right.. Remember the faster they go there clearance they like - I have a great article somewhere on modding the OS rod ends to survive IC ducted fan use - I will try to dig it up - Had an K&B .48 fan engine that I sent back because I thought they mis machined the Rod - very loose - Got it back with a nice note that the lower rod clearance was to spec and it had to be that way to survive- It ran well and lasted long - Sounded terrible turning it over though.
