Well Ive been reading about setting up a surge tank but am a little confused. I'm still going to gather parts either from for sale here or make do with what my brother has spare.
Anyway first thing is first. Ive read other topics here but I need pictures to see how everything goes. The fuel cap in my r33 gtst has 3 hoses... Out, in and I have no idea what the third one is.
I need these clarified before I go further. A picture I found on this forum showed fuel being fed to the fuel pump by one line then an overflow line going back into the fuel tank. Does the overflow line return back into the old return line from the engine and then the return line from the engine goes into the surge tank? This brings me to my next point. Would this cause the cycle of fuel to be the same fuel going to the engine and coming from the engine to sit in the surge tank? How does it get circulated quick enough? Is there a way to return the fuel from the engine back to the fuel tank to encourage the flow of petrol so it doesn't heat up too much or is it fine the way it is.
My setup would and most likely be as the diagram below consisting of the following pumps, bosch 040 pickup and a bosch 044 feed. Ive read about overpressurising the surge tank but some chap at boost cruising said he has been running a 040 pickup and twin 044 pushers for a while now and had no issues, he said as long you have an overflow line you don't need to worry about overpressurising.
Now my CAD professional level diagram:
Is it going to sound like someone is tanking a piss in my boot? I need some input here. Also, is it fine just to use EFI hose or do I need to use that braided shit?
If you could post pictures of your setups, that would be awesome.
This is going into a gtst currently on 330hp with potential for 380 - 410hp on fuel pump.
