Bosch fuel pump plubing ???'s

[pushrod243]

Ok Charley and Kurt I have my two new Bosch fuel pumps. They have a check valve on them to restrict backfeed after the car is turned off. It seems like that might be very restrictive. Should I ditch it or run them. I am still rounding up my wastegates etc for the turbo setup so i just want to install one pump to prove to myself i'ver cured the problem. Plus if it evers quits raining here I might drive my car while I'm waiting on parts for the turbos. Anyhow It has -8an hose feeding the pump and into the regulator which I plan to mount low on the firewall. And it has -6an return. Some guys are telling me to run -10an & -8an return for the turbos. Should I change it for the turbo setup then? I am setting up up to run a mild low boost setup 850hp goal but dont want to choke the fuel system. I am using the new fast controller since Rob @ Force could not get much response from Big Stuff. I like the idea of the new 02 sensor on the fast and Rod seemed to think that was a good system for me needs. I'll let you know how it works out.
