Orion Motor TechOrion Motor Tech Diesel Transfer Pump, 12 Volt Fuel Transfer Pump with Nozzle Hoses for Transferring Diesel, Kerosene, Self Priming DC Electric Fuel Pump Kit

This pump is straightforward simple and very well built - but with the sloppiest tolerances. Perfect for a solid foundation for a good pump, if you are mechanically inclined and would be interested in improving on it before use.These types of things are my favorite, bad enough to be inexpensive - yet good enough in all the right ways, that with a little improvement, it could be made really nice.If you just plug it in, and use it - you might rate it poorly.The wiring is not very thick for DC like maybe 18 gauge, so running full speed on, I imagine that would max out the ampacity of that size wire - but they have to keep costs down, so I understand, and it's perfectly suitable for my use, because I put an electronic motor speed controller ahead of it, so it runs only about 1/3 intended speed, and third energy load, so this Guage wire works for my task, if you wanted to run it full bore, you should probably keep on a strict duty cycle.The biggest issues were the fittings - I can 100% confirm that both inlet and outlet are 3/4 NPT . - But the threads are cut super duper loose, fittings rattle all around, barely catch, and almost fall out, and I tried several, certainly the loosest of threads, but it's for sure 3/4 NPT...No amount of pipe dope or Teflon tape is gonna seal those as is. Good news, the solution is simple, JB weld in reducing bushings to 1/2 NPT and problem solved, now it takes regular yellow Teflon tape and seals well no problem..The Best part is that it has a steel impeller head, Cast Iron housing and a simple internal overpressure bypass valve, a simple relatively large motor, and just 2 seals and 2 real bearings. Very nice, where it counts.It does have Nylon impeller blades - but every one you find would, probably or even worse plastic head or other internals, but I was going for a more extra durable, yet slower moving motor, so I cut my own Upgraded steel impeller blades to replace the included stock Nylon ones, it is now more robust but you couldn't probably run all steel at the full speed, I am run at a reduced speed, and full metal everywhere it can be, is durable for me.Just a simple largish brushed motor, 2 bearings, and 2 o- ring seals, and jb welded the bushings in.I fabricated a mate to an old CPU cooling heatsink and topped it with a dc computer fan to push away any heat from the now all steel impeller, it is running medium slow, it feels durable and reliable.If you just open the box and use it, you would expect maybe some issues, but if you are handy and like building stuff from close to good enough stuff, at an affordable price point, then this is a great platform and starting point.A very good but imperfect pump gets 5/5 - from me- with some effort you could truly craft it into something special for your project.

Easy to assemble, good fuel flow, and ready to clamp to 12 battery.

Does a great job! Pumps super fast. 5gal. In less than 30 seconds!

The device began emitting smoke, and the power cables melted shortly afterward. This smoke appeared even after we had disconnected it from the power supply for several minutes.

This is just what I needed

The outbound hose is too long. This allows for a couple gallons of fuel residual in the hose when done filling the tank. I sent a request to Orian for a shorter hose and or fittings so that I could shorten the hose. I explained that I went to the local industrial specialists who repair fuel and hydraulic hoses for local businesses. They could not shorten it because none of the Orion fittings could be matched by Industrial Specialists nor could their supplier. I went to a welding shop, same answer. So then I sent a request to Orion for a shorter hose and or end fittings. Their response - they don't sell these items, I would have to get the items in the local community to get these items.It would appear the person at Orion Motor Tech who responded to my inquiry did not even read my question/request for help before responding. Orion Motor Tech’s customer service was awful.UPDATE, Orion's parts are NOT compatible with ANY parts available at any of the local industrial hydraulic, diesel fuel hose, fittings, etc. businesses. Not one business in this community could match the odd ball sizing found in orion's diesel pump/hoses. Nor could Amazon or Ebay match the odd sizing found in orion's diesel pump. And this community thrives on logging which requires extensive quantities of fuel and fuel transfer equipment out in the field.The pump is still leaking. orion instructed me to remove the lid and check the gasket. I did this and the gasket was not properly sealing, which is a quality control issue. I asked orion for a replacement gasket. Their response-warranty expired, they don't sell replacement parts and they don't have that gasket in stock so go find a replacement in the local community. This stinks. This is the second time I have received this answer.

8-8-2025 was used for the first time worked great doesn’t fit into a regular 5 gallon gas can so I got a 55 gallon stump. Will give update after 1 year
