Default Fuel pumps for gasoline

My tanks are large up to 32 ounces. I have been using an outboard motor priming bulb. It moves about an ounce per squeeze. The only problem is I can not empty a tank with that system. I bought a famous maker crank pump that squeezes a tube with rollers inside the unit. The trouble is that it is so stiff as to be unusable. It would take 100 cranks to fill up one of my tanks. I can not imagine cranking it 100 turns. It also slides all over the can due to the velcro strap attachment.

I see that there are other gasoline safe crank pumps. None seem to move much fuel though.

I have been thinking that a 12V automotive fuel pump might work. The kind that goes in line inside the engine compartment. Anyone ever done that?

What works good for you??

I have used a 12 volt SMOKE PUMP from Don's Hobby Shop.
Can't get on that web site here at work to show it to you.

PS:
A fellow flyer has used a Car fuel pump and has worked fine also.

The Slimline manual setups work pretty well and I use 'em for my models with 32oz. tanks.

Please be aware that commecially made electric pumps sold for gasoline use have explosion proof hardware/switches installed and that is part of the reason they cost so much. Some guys don't bother with that explosion proof setup and seem to get along okay, but as a retired firefighter I'll tell you it's NOT a good idea.

I've been using a Holley Blue Dot for 25yrs. At 14psi it fuels all my giant warbirds, 24-50oz. tanks.

Will any of the mentioned electric fuel pumps pump the gas back OUT of the tank as well as IN to the tank? The electric pumps I have used for gasoline only pump one way. Thanks.

Sincerely, Richard

The Holleys run both ways, just reverse the battery connectors to defuel.

Kavan electric pumps work very well on either glow or gasoline fuels. Can be used to fill or empty tank. Doesn't leak. I have also used automotive fuel pumps, but the Kavan one is much better for our purpose.
