Actually, it lowers the pickup point. There was no strainer or fuel pickup hose before, so this arrangement can reach(almost) bottom of the tank. If it doesn't I can modify it a bit to do that. But, definitely better than before. I used submersible fuel hoses.
There are actually two hoses that goes into the strainer. The second one is a redundant on I made to add a redundant external pump.
I will open a second thread and post all the details once I get it going.
Tank and fuel in it is clean. But, I thought all of them should have a strainer to prevent any grime build up inside the pump.
