Looking for a reversible fuel transfer pump
I have a 12Gal aux tank that I want to be able to transfer fuel TO and
FROM my main tank. For simplicity and lightness, I'd prefer to use a single reversible pump on a single fuel line ... along with a solenoid shutoff valve in series to prevent gravity flow when off. There are cheapo plastic pumps available at a hardware store that would "do the job" but I wouldn't consider using one in an airplane. Yet I can't seem to find a QUALITY 12V reversible gear pump rated for gasoline. (I did find a few for oil and diesel at aptly-named reversopumps.com.) Anybody know of one? Pump capacity isn't critical, but would like it to be at least 3GPM. Thanks, Greg P.S. I say "gear pump" above because virtually all gear pumps are reversible by virtue of their construction, whereas other styles usually are not. But I'm not hung up on a gear pump as long as it can pump in both directions. |

Would it not be easier (and probably cheaper) to find a valve that can
switch input and output? Juan wrote in message ups.com... I have a 12Gal aux tank that I want to be able to transfer fuel TO and FROM my main tank.

Ya, that's another option. I doubt it'd be CHEAPER or LIGHTER than a
reversing pump, but if I can't find a reversing pump then such a valve may be my ONLY option. So OK, I'll bite: Where can I get a quality valve that supports swapping of inputs and outputs, and will handle gasoline? I actually had this drawn up long ago with a standard 4-way valve (such as used with fuel-injection), a pair of one-way check valves, and lots of interconnects. It seemed to be overly complicated. I can't find that sketch now, tho' I'm sure I can recreate it with a little thought. If there's a purpose-made valve for this, that would be GREAT. Thanks, Greg |

Maybe this will work.
http://www.reversopumps.com/valve_assemblies.html I think these folks have the reversing pumps as well.... http://www.reversopumps.com/download...Industrial.pdf wrote in message ups.com...

Geez, I just read your original message and saw you had been to
reversopumps.com already. Had you seen that valve already? wrote in message ups.com... Ya, that's another option.

Yup, I'd been to reversopumps.com early in my quest, and subsequently
contacted them as to whether gasoline was supported. They responded quite quickly: Nope. (Actually, it says this in their FAQ section too. But diesel would be OK.) Meanwhile, I re-drew the "plumbing circuit" using a single non-reversible pump and a duplex valve (e.g. an FS22-D2). It's not all that complicated ... but the valves is very $expensive. And I'd really like to be able to do this electrically rather than mechanically. So I've also been researching solenoid-actuated valves, and have put in some inquiries to several of the manufacturers as to their suitability for gasoline. I can obviously do it with a set of four 2-way solenoid valves, or with a pair of 3-way valves and a 2-way. But the #1 choice would still be a reversible pump for gasoline ... along with an on-off 2-way solenoid in series if necessary. Thanks, Greg |

Better off with the mechanical valve, for reliability. -- Jim in NC |

For simplicity and lightness, I'd prefer to use a single reversible pump on a single fuel line ... along with a solenoid shutoff valve in series to prevent gravity flow when off. You should be able to do this with two simple left-right switch valves. Doesn't cost much and it's quite light. http://www.aircraftspruce.com/catalog/appages/whfsv.php Rob |
