Correct Walbro Fuel Pump and Install Kit Part Numbers., GSS342 and 400-765 Options

[WannabeGT4]

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.

I'm about to buy a Walbro Fuel Pump GSS250 & 400-846 (. Im looking here at the chilton manual and it says stock fuel pressure should be at 38-44psi (265-304kpa)

The Walbro Fuel Pump will be used for 3S-GE Beams Redtop swapped 99 Celica GT. I currently am using the stock pump. So this upgrade to the GSS250 & 400-846 should be sufficient right. I also that that dr tweak on the pheonix tuning website says the 255lph pump comes with the install kit. From the link posted below it also says this comes with an install kit. Will I run into any problems if I buy it from this website, becuase of the install kit? What does the GSS250 & 400-846 mean in the model number. Is that the amount of kpa pressure it can handle. So its better than an oem pump right?
