 I have one of each. Been using them every week for the last few years. Only problem is if I let one sit for a few weeks, it is slightly stiff to crank for the first few turns. This usually only occurs during the winter months as I guess the castor oil in the fuel lines inside the fuel lines gets thick from the cold. If I cranked the fuel out before putting it away it may never happen. Other than that, very reliable......Gene

Anyone try the Hobbico or Dubro hand crank fuel pump. Wondering how they hold up.


Thanks,
MM

Motor.....I've tried all the rest....electric, Du-Bro etc etc....
The Dave Brown Six Shooter pump is the best for me and I do a lot of flying other than C/L.
This thing is so simple....no gears...no motors...no batteries....no drama.
Never gets stiff to turn even when pumping 22% straight castor fuel because the fuel never contacts any rotating parts....

   I have been using the 5 ounce veterinary "irrigation" syringe that I bought from Carl Shoup, but I used to use a Dave Brown pump, and it worked very well for a very long time. The only issue is to keep it clean and don't let sand or grit where the tube lives.

    The Dave Brown pumps are also rebuildable. If something happens to the silicone tube, a replacement is available for a few bucks. My wife was given a fancy coffee machine once, and it started to leak water. I checked into it, and it had split tube in it's innards that was similar to the Dave Brown pump tube. A replacement form an appliance repair store was 20 some odd bucks! The Dave brown tube was three bucks and just needed to be cut to length. Guess which one I used!!??

That's right Dan.....I forgot to mention the replaceable tube.
The Shooter is a peristaltic type pump. Check this link for a good view at how simple this thing is.

   I rebuilt mine once but only after *a lot* of gallons through it.

I rebuilt my Dave Brown recently, but only because I let it sit for about 20 years out in the garage and the tubing had sealed where the roller had pushed against it for all those years.  I could have re-used the same tubing by just removing it and exercising out the sealed section of tube, but after 25 years, it seemed a good time for new tubing.

Hahaha.....that's the best testimonial yet!
Looks like the replacement tube I have is going to go bad in the bag.

Dave brown also has a pump gas model.  I use one to pump the smoke oil in my scale Extra 300S.  Works great!

Pumps are not very good if you need a measured quantity of fuel onboard.  Sure count turns, but a syringe is better for the most part if you need to know the fuel quantity.

I have a Hanger pump and it works fine, a little fiddly after sitting a year but it comes right back after a couple turns.

    In any case, you want to fill the tank completely, then remove a measured amount, rather than just try to put in the right amount. That way, if any is left from the last run, you still end up with the right volume.

Does anybody offer a hand-cranked glow generator?  With that and a hand fuel pump I could get rid of batteries completely.

[john e. holliday]

Hey Paul, try the solar panel things I see at Harbor Freight and some other places.   I had the privilege of watching Dave Trible practice a bit this year.   He fills the tank and then pulls out what fuel he doesn't need.   I'm still amazed how the little guys can hang on to those big planes.  Hopefully more practice and coaching next year, right Dave.

I have two that could be used

One is a 1940s hand crank flash light from Army survival vest with 1.5 V bulb... squeeze the spring loaded lever to git dim or bright light depending on speed of squeezes


The other is ringer generator for a TA 312 army telephone... would need step down transformer and volt limit circuit...both easy

Now that you mention, back in elementary school in Detroit they let us monkey around with WWII surplus crank generators in science class.  We got shocked a lot, but nobody complained.  We were probably well into the illegal range.
