The GSS-342 fuel pump and 400-765 install kit are the correct Walbro part numbers for our cars that are swapped or turboed.

I bought the GSS-341 since that's what I found to be recommended during a search here, but it's inlet and outlet are reversed compared to our stock pump...

Our stock pump looks almost identical to the pump on the left. The Walbro pumps in that picture are identical except that the one on the right has the inlets and outlets offset for use in the MR2 Turbo and Supra TT. That is the only difference between the 341 and 342, they are both 255lph Hi Pressure pumps.

I got the GSS-341 to work but it doesn't sit in the pump bracket correctly. A zip tie was added for peace of mind.

Also, on the stock fuel pump plug, the blue wire is the positive 12v source. It is to be spliced into the red wire on the Walbro plug. Obviously, the two remaining black wires will be spliced together.

If anyone has any advice on how to install the filter retaining clip let me know. I finaly got it to go on but it sure seemed like it was more trouble than it should have been.

Why did you buy the 341 instead of the correct part? That's the whole point of this thread.
