To Fpr Or Not?
#1
Dragon originally brought this up in my Cosmo Update Thread in the first gen section (RIP). I had to purchase a KGParts primary rail, to make a long story short, thus ditching the stock FPR for the primary rail. I'm still using the stock secondary rail w/ modified Bosch 1680s which has a FPR on the rail.
Now, I would like to know what would happen if I didn't buy an aftermarket FPR and what the advantages of buying one would be. I really don't know the relationship between fuel pressure/performance/etc and it'd be nice to open up a discussion about it for my education, haha.
Let me know what you think. And just remember what it says in my sig...

That thing on the primary rail is a pulsation damper not a fuel pressure regulator.
If you want to run a aftermarket regulator you'll have to either get a different secondary rail with fittings on it or chop off the ends of the factory rail and weld on fittings. I chopped off the ends of both the primary rail and the secondary rail and welded on fittings so I could use a adjustable regulator. To be honest I don't think it will matter all that much either way for you.

Stand-alone EMS, right?
Then it doesn't matter than much.
Top-feed ND fuel injectors are fine up to 70psi of fuel rail pressure.

Yes I'm running a Haltech E6X.
Thanks for the helpful info guys.

Steve Kahn had talked about that and the way to set up the regulater or what ever.
What problems does this pulsation cause and how to install the aftermarket secodary rail with the FPR?
