Sorry I have rejected electric pumps entirely. Here is what I use and the reason is not entirely reliabilty it is the lack of ability to count turns of fuel in and fuel out for consumption estimates.
The first picture is for glow and the small syringe with tygon is for vintage gassers and the small diesels. The next two pictures with the five litre gasolene container are for my big gassers, The neoprene hose is soon going to be replaced with tygon since the neoprene does not last much more than a season.
