go for the AMS rail..it is predrilled for an FPR gauge, or you can go for this:

Personally I hate running other companies logos. This is why I choose the ATP fuel rail.
Evo 8 Billet Fuel Rail system. Fully configurable fuel rail system designed for all possible combinations of use including, stock regulator and lines via adapters provided, aftermarket Aeromotive style FPR use via 1/2 NPT port for up -6 AN to -10 AN feed and return using steel braided or pro stock lines. Comes with billet brackets, gauge port, EVO 8 machined and Polished to a mirror finish. Largest inside diameter, highest flowing, most modular and well built EVO8 fuel rail on the market!

I'll second the notion that upgrading the fuel system excessively or prematurely is never a bad thing. I listened to all the people that said the 255 pump has run 10s on so and so's car, etc, and it cost me a motor. Different setups require different amounts of fuel to get the job done. Rather than wait for a blown motor to tell me the 255 was too small, I should have upgraded sooner. With the EVO, the stock pump was keepng up with my demands, but barely according to the math, so I upgraded to a 255 and an aeromotive reg with a 3/8ths return to the tank. Naturally I saw no performance gain from this, but does that mean it was a waste of money? Not at all. It's cheap insurance.

Good point, but here we are advising someone with a stock turbo, which is a far cry from anything that can stress a 255 lph pump.
On the other hand, were we speaking of a GT35R setup that was truly capable of 550+ whp, then a single 255 lph shouldn't be expected to be sufficient.
There's a big difference in 'insurance needs' between a 10 second car and a 12 second car.

I do agree with you here. I think I am just now overly paranoid and go big on the fuel system whenever the oppurtunity arises
A clean install for a pressure sender, or a tap off point for a nitrous kit, etc, would be more than enough to get me to buy an upgraded fuel rail.

I have seen both the Perrin and the Agency Power rails on cars. Regardless of if they are needed or not, I liked the Agency Power one a lot, and they have some pretty cool colors also, if that matters to you.
