I think it is the height of the inlet hole. It seams the fuel sloshes out of the cup inside the tank some. the stock sock and inlet hole position is smack on the bottom of the cup inside the tank I think I may be higher. I'm going to try and use the miata sock. I may have to reorient the pump and re make my adapter but I can make the miata sock fit the pump maybe I can get it closer to stock inlet position.
I like this pump because you cant even hear it when it is on. The Walbro makes my ears ring after listening to it for extended periods of time whining away right behind my head makes my teeth hurt.

You have to figure the inlet hole in the tank is the important height, not so much the sock. You may have to bite the bullet and go to a swirl pot. Running really sticky tires?

At 1/2 tank my car starves for fuel and sputters when I corner to the left and only when cornering hard left. Sure seems like a fuel pickup issue. some serches on Miata.net showed others had this problem but the source of the problem was not always clear. Mine has an entirely bran new fuel system, new lines New fuel filter, and a new fuel pump. Fuel lines have all stainless -6 AN ends silver brazed on the hard lines with AN fitttings everywhere. Fuel filter is like a stock one but is setup for AN fittings as well. Fuel pump is not stock It is a 50mm Denso supra pump and the mounting has been modified using RX7 bracketry to make it secure and fit. The sock on the fuel pump is also not the same as a stock miata one. the depth the sock sticks in the tank might be 1/4" higher than stock due to the angels but I have a hard time believing it makes that much diffferance. Pictures attached It seems like before it would run down to the last teaspoon of gas in the tank. is it really possible this sock on the pump is making that much differance? Any Ideas Bob
