What is the best way to hook up a electric fuel pump to a gallon of gas. Do I need some sort of cap on the gallon container with a line inside and a vent? Some small brass tubing through the cap? Thanks.

Use the parts ABELL mentioned (or similar) and install to your jug or can top. Once installed leave that cap on and don't take it on/off all the time because this gives an opportunity for debris and other contaminates to enter the fuel. If you are going to store the fuel for a month or more without use then put the regular cap back on.

When I first started flying I asked about an electric fuel pump. never forgot the answer.
Why an electric fuel pump, if your battery goes dead you cant get fuel...with a crank fuel pump and a chicken stick your good to go.
Never have bought an electric pump
have fun

I keep a fuel syringe in my flight box. I've loaned it out on several occasions to people when their hand pumps have failed. My electric pump has never failed to pump although it did start to leak once and was replaced for that. Not bad for 30 years I guess. I have had gel cells go bad though.

Funny,

I have had 2 electric pumps....both failed within 5 gallons. I think they're junk., a needless piece of powered equipment. Get a quality hand-crank. I don't fly glow anymore and I still use a hand-crank on my gassers.

I like using the electric pump, push button easy, one of mine died it was replaced free of charge,years ago I did the crank thing as cheap as they are I will go with the little buzzer.

I like the electric pumps and electric starters! I work hard all week and I don't feel like working that hard with my relaxation hobby.

The electric pumps can sometimes fail pretty quickly. Mine didn't last long at all. Also they can put out a good amount of pressure and can spew fuel all over the place. A couple of years ago I was having some trouble with a trainer that I had and one of the guys said "here, let me show you" and grabbed my plane and started pumping fuel with the electric pump. Well the fitting came out of the tube and sprayed fuel all over my face. Arrrrgggghhhh.... the dumb thing doused my eyes with fuel so bad I couldn't see. He grabbed my arm and lead me over to a water faucet and I rinsed them out. I eventually had to go home and rinse them in the shower for a while. Now adays when someone starts up those blasted things I steer clear of them. [>:] I think they were good back in the days but the crank type now are very good and safer to use and you won't use up your battery.

You blamed the pump because some idiot didn't hook up the hose properly?

I also keep my face away from the fueling operation when running. That's just common sense.

The pump "used up the battery"? Oh, come on now. Did you run it all day? Charge the battery occasionally when at home.

I'm as lazy as they come and that's why I don't own an electric starter, fuel pump, or any other gadgets that create more work than they save.

I hope I read the first post right, "an electic fuel pump with gasoline?????" Not recommended unless you have one designed specifically for gasoline unless you like unplanned fires. If the author means glow fuel, then ignore this post.

I hope by "gas " you mean GLOW. using an electric pump with gasoline could be a disaster.
hobby electric pumps are usually not built very sturdy. they operate on the vane principle and any starvation wears them quick. as does dirt. filters are a MUST. still ive only averaged 2 seasons use before trouble starts. a better option is to buy a windshield washer pump at the auto store . just be sure it can be reversed. the volume is greater and the construction sturdier.
