As far as hooking up the existing fuel lines to the Lexus V8. I'm not worried about this. All EFI needs about the same amount of pressure and being Toyota it should just bolt right up almost. I do plan on installing a pressure gauge/regulator as they run around $50-$70. I think I have one laying around that I used on a previous car. As long as I don't modify the engine much I will be safe with the current system. I'll just have to make sure about the filter as the 3RZ engine has the filter attached directly under the manifold on the engine itself.
Not a big deal at all. I'm more concearned with what I'm having for breakfast tomorrow morning.
So I did a little checking and the fuel filter on the LS400 is near the middle of the chassis underneath. It's a simple filter and I will have to add a filter inline somewhere. I could put one underneath by using a flare tool but I want to make sure it's not vulnerable to rocks or anything. No stress. I'll figure out a nice place to mount one.
