Thread: Electric fuel pump, or.......??

Tweet

The last two fuel tanks we built, we used stock GM in-tank pumps...you can buy them in either low pressure or high pressure models (either throttle body injection or high pressure injection). If you buy the AC part number, they are about $42 each. We put two in each tank and wire them separately so you can swap pumps if one fails. The fuel lines from the pump have check valves to prevent back flow from one pump to the other.

The pumps are submersed in gas so they are quiet...and run cool.

The only downside is that you have to have a large enough access hole to get them thru...maybe a 3 inch dia hole? We have a bigger hole since we used fuel cell foam and had to have room to stuff it.

I got my replacement SS tubing from McMaster Carr yesterday afternoon. I'm about ready to fit up my new line in an attempt to stay with the mechanical pump. I have two 90* bends with only 2" between them and are using some "gold plated" SS AN- elbows to do that. I do need to make four more fairly tight turns, but not 90's. Yes, I do have a tubing bender - mediocre quality for 3/8". My concern is kinking. I used a sacrificial piece hydraulic line and a bit thicker, and instant kink!! Others have said sand inside the tubing then the bender will work fairly well to keep the turns reasonably neat. Has anyone tried that method? This SS tubing takes too long to get to me as well as being fairly expensive to waste
