Default Looking for CHRS1313 dual pump experience

I am just about ready to purchase a chrs1313 dual 450 fuel pump kit, and I am looking for 1st person experience with this system. I would prefer to only hear from someone who OWNS a car with these pumps and/or someone who INSTALLED the pumps.

How does the kit fit?
What pumps?
If you used the vent/evap line, were there any issues with the stock connections?
What feed lines did you use?
What return lines did you use?
What regulator did you use?
What is your fuel rail pressure?

I have it. Fits very good. Pumps are walbro 450s. Why would you use a vacuum line? You mean at the regulator? Im running -8 feed and -8 return running to an aeromotive regulator. I set pressure to 60psi key on motor off, hooked vacuum to the regulator, then disabled the vacuum/flow rate table in the tune.

i never installed the chrs1313

however i did install and run the lonnies doubles (sponsor on here)

flawless install, i believe he uses dual 340s tho, not certain. great customer service and extremely knowledgable.....i would recommend reaching out to him to answer your questions.

http://www.lonniesperformance.com

his site isn't the best and is a little tough to navigate but go look under fuel systems. his is cheaper than the chrs1313 as well i believe.

Can the dual 450 setup like this with FIC 160 lb injectors support 1300 rwhp (TT 427 application 6466’s) and if so, what is the max duty cycle going to be at? 80% 90%?

dual 450 would do at least 1500 on 93. assuming the rest of the fuel system can do it

Going to need more pump then since I want to run E85.

Aeromotive 5.0 external pump with a 12 AN sump to the factory tank and dual pumps in the bucket that can handle E85 should cover it.

This looks good:
