Just wondering if the Walbro fuel for the 4g63 is the same fuel pump and part number for the 420a?
 
A fuel pump is a fuel pump. It's aftermarket and not a literal drop-in replacement for most [if not all all] applications.
 
a little but of trimming of the sending unit and or hose that comes with the pump. not all that hard....

I found a tutorial on 2gnt.com yesterday your right not to hard, but I want a clear answer are the walbro part number the same for the 420a and the 4g63?
 
Im 99% sure they are the same.

I realize a "fuel pump is a fuel pump" but chysler makes the 420a, mitsu/4g63 and there is alot of differences between the 2 cars.

Im 99% sure they are the same.

I did some research they are the same, at least the walbro pumps are.
 
ALL 2G cars use the GSS342 pump if its a 255lph. If its a 190lph pump, the number shall be GSS250. The install kit that comes with the pump needs to be 400-847.
There are two 255lph pumps- 341, and 342. The difference in this number is that the 342 has the inlet and outlet on the same plane- this is used on the 1G FWD and 2G FWD/AWD cars, and on the 341 pump, the inlet is offset from the outlet.
