While working on the fuel cell on my 1995 R I noticed that the fuelpump is a different design than the standard 1995 Cobra/GT. It appears that among other things (Air Cleaner, Alternator, etc) the fuelpump for the 1995 R was pulled from the 1996 Cobra parts bin. The 1995 Cobra/GT used a center inlet design and the 1996 Cobra/1995 R used an offset inlet design. I have an almost brand new 255lpr center inlet pump that I was going to install in my fuel cell until I noticed the design difference. I was able to install the center inlet pump by swapping the fuel pump assembly cages but I'm concerned that I'm missing something. I can't image they would use a completely different design for no reason.

Can anyone explain the reason for this difference? Will it be ok to run my center inlet pump?

Here is a pic of a center inlet pump used in 1995 Cobra/GT Mustangs.

Here is a pic of an offset inlet pump like the one pulled out of my 1995 Cobra R.

I have a list of 95 Cobra R specific parts with matching part numbers. On this list it states the fuel pump as a specially modified 190 lph pump, p/n M-9407-C50. Not sure what the specially modified part is though.

The standard mustang and cobra used a 120(?)lph pump.

The cobra r used a 160lph pump which I believe was a pull forward part from the 96 cobra stock (similar to the mass air meter).

The street and normal Cobra did not use a 120. It was a 90 or 88 from memory.

190 for the R. It was from the Motorsport catalog.
