Some questions, and Fuel pump? (with pictures)

Ok, so first thing's first. I bought a "Supra" Fuel pump. The reason why it's in quotes is because I question whether it's a real Supra TT Fuel Pump. Well here's a picture of what it looks like:




The main reason why I question whether it is a Supra Fuel Pump is because it says Walbro on the side. I was pretty sure that the Supra Fuel pump was Nippondenso wasn't it? This isn't a Supra Fuel Pump is it?

Also, here is how my engine bay sits right now:


Well, I've got some things that aren't quite connected yet:

Where does that hose go?

Also, for the ECU what does this line go to?




Thanks a lot for the help everyone.

Well, that hose goes from the stock plastic catch tank to the charcoal canister. I don't know how that should be set up for a single setup, but you should have or get a single turbo vacuum diagram. I just looked it up and it shows it hooked up like stock with the catch tank, the purge control solenoid, and check valve.

The wire looks like terminal 2I on the ECU and the FSM says it connects to the "heat hazard sensor". Unfortunately, I don't know what that is, but I found this thread on it: https://www.rx7club.com/showthread.p...+hazard+sensor

yea that doesn't look like the supra pump. I put one in my car and it looks pretty similar to the stock pump and IS in fact a Denso.

The supra pump part # should read 195130-1020, located on the top of the pump.
it also i believe has a grey top while the FD has a beige top.

They look identical besides that

Ok, I've got a better picture of that line:



It's the one that's like whitish, and then becomes red.

that is not a Supra pump it is a Walbro 255, the wire is for your knock sensor pin 3M in your ECU, and the second pump is the stock FD fuelpump.

Ok, so here is what I have concluded:

I got the Walbro 255 Fuel pump
The wire is for my knock sensor
The second pump is a stock FD pump when people don't premix.

1 Last question, may be a noob question, but do I HAVE to have the knock sensor hooked up? and if I do, where does it connect to since mine is disconnected?
