[Gmecm] In-line fuel pumps with TBI

[Charles McDowell]

The filter is about half air.  It's about 1.5 inches in diameter, so I don't
know if it's realistic to expect it to be solid with gas.  

If I pull the line at the filter input, gas will pour out continuously from
siphoning, so the lines seem clear.  I guess they could be partially kinked,
but I sure don't think so.

I've always used the inline filter before the pump as a poor man's surge
tank / to help hold fuel near the pump so I wouldn't have to manually prime
it.  The pump pumps the fuel in the filter first, and that causes a vacuum
siphoning from the tank..

How much air is in your filter?  You didn't pinch the fuel line to the tank,
or put in a plugged up fuel pickup, did you? ;)
