Best way to run 2 intank pumps?
I have seen it done with one pump for each rail or Y the pumps together in the tank out to one feed line. I want to know wich is the best way of the two. Or is there one good intank pump that will flow good.
I am single t04s, 850 primary, 1300 sec with -6 an lines.
Looking for around 400-450rwhp and want to have enough fuel for 20 psi.

well, here's my opinion: I'm running two "in-tank" GTR fuel pumps (1 to each rail), but to fit them down inside the tank, some baffels were removed and now I wouldn't want to run anything less than a 1/2 tank. You could get away with two Walbro fuel pumps, because they're small.

I have two nipendenso pumps with -6 feed and return. One pump feeds the primary injectors and the other feeds the secondaries. This way if one pump fails, I'll know and won't blow my motor. If you Y them togeather and one fails under boost, you can detonate if you go lean.

So if i run one to each rail, then if one fails under boost the engine will just shut off and not pop do to running lean? That was my concern with running one to each rail. I will be running dual walbros.

One of the big problems with dual in-tank set-up's is that most people don't run separate baffles for each one.
It's highly recommended to run a baffle for each in-tank fuel pump.
This is where the surge tank system is superior.

There was an add for a complete pre-made package like this that is a straight dropin. It was custom made with new engineered parts and AN fitting. Saw it somewhere on one of the RX-7 forums, or sites? It looked like OEM.

That is a nice looking pump setup. Does anyone have any experience with it? I just want to make sure that it is going to be a sound setup for AutoX and drifting. I know that a surge tank would be the way to go, but for the price this looks to be a very nice setup.
