It frustrates me as I have read people installing the supra pump and driving away, and my car is stuck at their garage till Monday to sought it out.
I have a supra fuel pump. I took the soarer to a garage. They modified the bracket, wired it and then bolted it up to test it. It did not start the first few goes, then eventually the engine did start but for only for a few seconds then stall. Is that because it's not getting the right volts?

Wire runs from battery (drilled a hole behind the charcoal canister), then goes down and along passenger side of the car, to where the fuel ECU is on passenger side beside rear seats. At that point the feed goes to a 12v 40A relay I got from autobarn. Then the switch leg from that goes to the pump through the wire point on top of passenger side you will have to take rear seat out to get to this goes into the boot. Then fed wire to pump (take of circle cover behind rear seat. Wired up the new pump (hard bit here is the 12v line into the tank) have to do it in such a way that you make it safe, and have no leak.
Back at the relay wire one trigger leg to ground. The other leg goes to the 9v-12v wire output that used to go to the old pump.
That's it, works like a charm, uses the stock fuel pump ecu, and it will even last longer. ECU dies because of the power transistor in it making it cook, now through the relay I believe has higher resistance, less current, and less heat...has worked fine for me for 2+ yrs now.

I've got a supra pump and I use a relay near the battery to switch it on /off.
My problem has been that on launch and hard accel. I get heaps of fuel surge. I've changed the fuel filter (what a c.unt of a job!) and I think the only option now is to re-seat the pump and see why its surging to bad.
Alternatively I may just run a surge tank and set it up properly.

I'll have to check the install and make sure that it has been done properly. Anything under 1/2 tank = surge on hard accel. I've got a good setup for drag racing with no loss of traction due to the soft setup so when it hits boost or launches - the car goes back a fair bit to grip.
Regardless - it must be fixed if I have any hopes of running 10s in a soarer streeter

Check to see if they mounted the Fuel pump Cradle in backwards . If mounted backwards the pickup is on an angle and sits alot higher which will cause surge down low .
