|An empty fuel tank isn't empty...|
|Written by White Spy|
I should have written this last weekend, but I was sidetracked. I'm now avoiding writing a paper that was due in mid-August, so I'll post this here.
I replaced my fuel pump last weekend with a Carter pump from Lordco. Incidentally, that Carter pump is actually made by Walbro and is slightly larger than the stock pump. I'm not sure what the lph on it are though...
Anyway, while doing the fuel pump replacement, I found out why we can usually autocross a Miata without problems with the fuel gauge reading below E. The fuel gauge float sits out in the main chamber of the gas tank while the fuel pump sits down in a well that appears to be about as big as a 2l milk carton. So, when the fuel gauge reads empty you will still have about half a gallon left.
Having done the pump R&R, the car feels better and doesn't appear to starve anymore, so I guess I can go back to running the tank below E when racing. Woohoo!
Now I just need to check the plugs again and source out a set of 1.8l injectors...
