How is it that you install 2 fuel pumps?Anyone have a website on the how to or can someone explain how this works in detail?

The easy way would be to clamp them together and use a 3 way brass splitter to merge both pumps into the 1 stock fuel line. You just have to make sure that the 2nd pump can pick up fuel well.

Ok but how do you mount them so that they pick up the fuel,obvioulsy you would have to mount them outside the tank so this is where I need to know how.How to mount them both outside the tank and how they get fuel outside the tank?



Also,is there enough current back there to run them both?

Oh, I thought that you were trying to do it in the tank. Here's a picture of that setup:

If you want 2 external pumps then you should add a sump to your fuel tank. If that's what you want to do let me know and I'll explain it.

Hmm,well I would love to do 2 pumps in tank if possible.That looks about the same as my third gen assembly but with an added pump,am I correct?From those pics it didnt look that hard to do,again am I correct?Will that setup work on the 3rd gen too...Lets say 2 supra pumps?

That's an 89-91 TII setup, but it's the same for a 3rd gen. 2 Supra pumps will work well, but I would recommend upgrading the fuel lines. The stock lines are kind of small. I use them on my car, but I shouldn't be. Just don't tell my car. One way to do it would be to weld a -10 steel bung to the fuel outlet of the fuel pump assembly and run a -10 line all the way to the fuel rails.

What is a "Bung"?



What is -10?

-10 refers to a particular sized AN fitting. A bung would be a male end, sort of like a female O2 sensor bung.
