Fuel tank draining and cleaning

Thanks for all the input. Went to Pep Boys yesterday looking for a universal electric fuel pump. They had no idea what I was talking about. They asked me what make and model car I was working on. I did'nt tell them.
Saw one in JC Whitney that I will order.

Co2 evacuation is a good idea. My wife has a 55 cu ft helium tank that I could use.

I'm very cautious with fuels. I used to work with things like 100% Hydrogen Peroxide, 100% Hydrazine, Amonium Perchlorate and the like. Boats aren't rocket science but I was a rocket scientist!

Thanks again,
