Wow that is a really clean setup.

I believe I use the same Flo-Fast 7.5's and their best hand pump. I fill up the two containers at Farmers supply us using 90 octane, unleaded no alcohol for my Rotax ULS and hand load and unload them into my SUV. I unload them and hand pump the fuel into the RV-12 which is located passenger side behind the rear window just behind the wing. My question is where should I ground the container?

The FLO-FAST pump has a ground wire attached to the pump. I attach it to the two-wheel cart and then a wire from the cart gets attached to the tail tie down ring.

Strap is made from Home Depot mild steel strip.

I finally got to try the entire system now that the Pro Seal has cured on the boat deck filler tank flange. Absolutely the nuts? I?m through lifting 5-gallon gas cans to shoulder height to pour into the RV-12. The FLO-FAST pump is easy to turn and outputs about one gallon for 10 turns. Today I rec?d the digital rev counter and I will make that part of the system and report out when complete.

I changed the 5-gallon pouring snout ? it is now a straight piece of ?? ID FLO-FAST tubing. This makes it easier to pour into the boat deck filler flange. I also changed the way the 5-gallon jug vents to allow a more vertical (fast) pour. This is still a work in progress but looks very promising. I?ll post photos when complete.

Suffice to say, I am very happy with the FLO-FAST. This should help me fly another 10+ years at which point I will be in my late 70?s? God willing.

Thank you.
I don't use a cart but if I located a grounding wire from the pump to the tie down and a ground cable from the tie down to a ground in the hangar would that serve as well?

And now.... the simpler solution.



Sorry, couldn't resist. :D

I have the 15 gallon version of the Flo-Fast with pump.
Instead of pouring the gas into the 15 gal container from the 5 gal ones, I simply set the 5 gal jugs up on a shelf or chair and use the pump, turning the handle backwards, to pump the gas into the 15 gal jug.
Instead of getting a cart, I just set the big jug on a small furniture mover from HF and it rolls around just fine.

I never considered running FLO-FAST pump in reverse to transfer from 5 gallon to 15 gallon. Good suggestion - and simple too...

Being tall at 6'5 makes for removal of a lot of the seating and back rest cushions in an RV-12 necessary and replaced with lawn chair furniture pads, so my head has clearance for the canopy to close.

On the plus side, I ground my arm against the skin of the plane while holding the 6 gallon plastic jerry cans while filling up the tank. I do need a quiet stretch of time from other plane noise at the airport to hear the gas starting to come up the spout, however.

To each his own, for now, the exercise is good, and filling up with premium at Costco is easy enough. I have 18 gallons of capacity, the Moller gauge on top of the planes gas tank is very good at letting me know how much I need to buy.

The strange part is when people see me pull up at a gas pump in an All Electric VW e-Golf and wonder what I'm going to fill up, until I lift the hatch back and grab the jerry cans.
