Portable Fuel Transfer Pump and Filter

Pump and Filter in Plastic Box
Have you ever siphoned fuel and got a mouth full of diesel?
Have you  ever transferred fuel to your boat with jerry cans and other fuel containers with no pouring spouts?
Need a quick and easy method to transfer fuel?
I recently made a fuel transfer pump with filter for transferring diesel fuel from tank to tank or jerry can. I needed this through out South East Asia, where the fuel most often was not clean. I also had to obtain fuel in jerry cans as fuel docks were few and far between. This necessitated pumping out of the jerry cans so that what went into my tanks, went through a filter first. Since then, I have also used it to pump fuel between tanks so that I can clean the fuel tanks from time to time. In fact, if my tank is not heavily contaminated, I use the pump system shown here to "vacuum" the bottom of the tank. The fuel filter stops all the contaminants and separates the water out.

 CAV Filter
I used a CAV filter housing similar to the one shown to the right, along with an oil tranfer pump (12V). The filters for these are readily available in most countries around the world, and quite cheap.
The oil transfer pump, which I use for the diesel fuel, has a switch on the end of the pump, which makes for easy on/off operation.
It was just a case of connecting the hoses, hose tails, and wiring with a long piece of duplex wire with alligator clips to connect to a power source. This was all placed in a plastic box for ease of handling, and to keep it "water proof" as I store it in my aft lockers, where sometimes sea water will get in.
Packed and ready for it's Lid
The filter housing was mounted to the side of the box to keep it upright.
Hoses are easily stored with the pump and the whole setup is ready to go. I used fuel line hose.
Warning! The pump I used is OK for diesel fuel, but Not  for use with petrol.
To keep the whole lot from having fuel leak into the box, I used rubber bungs on the end of the hose. You can see one on the hose in the picture to the left.
You can also use the box for a diesel rag, if you use one from time to time
