93-94 Cobra's have 110lph pumps. The pump mount/assembly is different on the 94/95's though. The diameter of the fuel out line is larger I forget what the 96 and 97 Cobras are rated at, but the 98's are 190 lph.

Yeah, some people say 90 or 92 lph... but I figure after 100,000+ miles 4-5 lph doesn't even matter. I don't even know if fuel pumps are 5 lph accurate in their rating. You also have to consider these pumps are electric motors. For those who have been into R/C cars, you know very well that after running a while, motors get hot and slow down. I wouldn't be surprised at all if a 110 lph pump flows 90 lph after a one hour drive in the summer time.
