[Tech] Walbro install into Supra info here.

Well thanks to 7M-Brisbane and Norbie for giving a hand, I installed a Walbro pump yesterday, thought I would document it incase any other Supra owner wants to do the same.
First unscrew the 4 screws holding the cover of the fuel filler on and take it out.
Jack the car up under the diff and put jack stands under the car as you will need the jack to help support the fuel tank.
Unbolt the plastic shroud cover at the front of the fuel tank. There are 4 bolts to undo. It's can be alittle tricky to get out.
Here is the cover undone.
You will need to undo these lines to get the tank out. One of the clamp hoses is the breather and the other the fuel return line. The bolted section is the high pressure line. You will need a 19mm and a 14mm to undo this. The 19mm section is the one that undoes. Watch for fuel spillage here as there will be abit if the line is still under pressure.
Here are the two bolts that hold the fuel tank up. Undo these bolts but not off. Only loosen them off abit.
Unplug the fuel level sender sensor wires from within the boot.
Now with the jack and a peice of wood/books to spred the weight onto the jack, put it under the tank between the two straps. Now jack it up alittle to give the belts some slack. Take out the pins for the belts and undo the bolts to remove the belts.
Reach up and disconnect the fuel pump connector from the car.
With abit of loweringof the jack the tank should be able to be lowered out, make sure that the tank comes to the passinger/left side of the car while it's lowering to get the filler out.

Remove the screws that hold the fuel pump backet in and remove with a slight twist. Make sure you know how it came out as you have to put it in the same way.
Fuel Tank with Stock Pump
Here is the Walbro installed on the bracket. I had to cut the bottom of the braket to open up the hole alittle so the walbro fits though. Take note of the wires because if you put the wires on the wrong way the pump goes backwards and the car doesn't run.
Here is the Walbro on the braket. With the wiring I just used spade terminals crimped onto the wiring. You will need to install the filter onto the bottom of the pump of course. Make sure the filter faces the same way as the old one otherwise you can't reinstall the pump.

Excellent work Nick, I'm sure someone will find that extremely useful. FWIW the procedure is almost identical for an MA61; I did mine about 6 months ago.
As for flow rates, yes the high-pressure Walbro pump can flow 255 lph and yes it can provide 110 psi fuel pressure, but it can't do both at the same time! They flow approx 320 lph at 0 psi and 35 lph at 110psi. Flow data can be found here.
The above web site retails Walbro high-pressure pumps for USD$109, and they're available with plug-n-play kits for MA61 and MA70 Supras. That's where I got mine from and it was a piece of piss to install as it had the correct wiring, fuel hose, rubber mount etc all ready to go.
