I have no illusions that this will put me in the running for the grand prize, but someone here might find this little gem usefull. Especially since it can be made for about $23, and it's self priming. Also, it's practically bullit-proof! At the VERY LEAST, I'd like to contribute SOMETHING back to the HAMB for all it's given to me. I make bio-diesel, and I use one of these to pump used vegetable oil. On more than one occasion, I'v had 50-60 gallons of water in the bottom of my veg-oil tank, and this little pump has sucked it up without so much as a quiver. You could use this pump to: Drain the cooling system before working on a car. Change tranny fluid without droping the pan Change rear diff fluid Clean up oily messes Empty barrels, or transfer fluids Empty gas tanks [dont get any ideas, punk!] Or even move water in a pinch. It's designed to be used in oil, and it will require some lubrication. So if you do use it to move water, try and limit it's use to just a few minutes, and then run some type of oil thru it to protect it. Ok, here we go... How to turn a SBC oil pump into a utility pump for cheap. Here are the raw materials used: 1 small block chevy oil pump from autozone @ $15.88 [tax included] 1 package of J.B. Weld available anywhere @ $4.23 [tax included] 1 section of 3/8 I.D. pipe from home-depot @ $3.17 [tax included] [I used a 10 inch section. Your needs may vary] At first, I was going to use these 3/4 inch screw in barb adaptors that I got from Lowes for $0.88 cents each, but upon closer inspection, it was revealed that there was not enough "meat" in the oil pumps casing to support drilling a hole this large. Building the pump: Step one, dis-assemble the sbc oil pump by removing the 4 10mm bolts that hold the housing together. Remove all internal components, as shown The 3/8 iron water pipe is pretty darn close to the size of the existing opening for the oil pumps intake, but it will have to be slightly enlarged to fit properly. This is where the "new" outlet for the pump will be. This hole will have to be drilled right into the side of the casing. Start by clamping the base of the oil pump into a bench vise. Get the largest drill bit you can get your hands on that's capable of cutting metal. This one I'm using is 1/2 inch. Start drilling down to enlarge the inlet opening untill the iron pipe fits into it. It only took about 40 seconds to "woller" out the hole untill the pipe fit. I stoped when about 1/3 of an inch of it would fit down in there. Whoops!!! I made a mistake! I got a little too carried away with the drill bit, and drilled thru the factory installed plug for the pump bypass. No big deal, we'll fix it later... Just lucky we caught it early. Now we have to drill the hole for the new outlet, right smack in the middle of the case. Clamp it into the vice and drill away. It's really surprising how easily a good drill bit goes thru cast iron. Once thru, work the drill bit back and forth to enlarge the hole to fit the 3/8 pipe... But dont go too far.
