Fuel Setup Questions

[Beckholt99GSX]

Ok so here is the plan that I have, any suggestions or issues anyone has would be greatly appreciated. This is on my 99 GSX

1050 injectors with -8an feed line, RCI stainless steel fuel filter, -6an return line, fuel lab regulator, stock fual rail, full blown dual pump hanger, deatsch werks 300lph pump and evo 8 pump (roughly 490lph combined)

I guess my biggest concerns are if im going to have high fuel pressure issues? Ive read about drilling out the siphon to allow for better flow and lower fuel pressures, but from what I've gained that has always been on the stock return line.

The other issue I was thinking about was....can you run two different size pumps or do they need to be the same, and if there is a way to have one activate after the fuel pressure rises to a certain extent.

I'll be tuning with V3

Any suggestions would be great thanks guys!

What gas are you planning to run? Pump 93 or E85? What turbo and how much airflow are you trying to acheive? The 8 feed and return sound like a good choice. A dual pump hanger with two pumps is going to really give you some fuel. That why I ask how much airflow/fuel you'll need. Single drop in pumps have come a long way. Like the walbro 400 can support a good bit of airflow.
