Airdog II, Sinister Regulated Return Compatible?

[paradiserfd815]

I just installed the airdog and now would like to do a regulated return. I read a post here that says two regulators in a system would be hard to maintain constant pressure. With airdog do i need regulated or could crossover hose work? If so where can I get one. Just wanting to bulletproof the fuel system to save injectors. Any advise is welcome!! 05 ARP, egr delete, mbrp, sct livewire, pillar fuel pyro boost, airdogII, 58v custom ficm, royal purple 15/40, rev-x.

was wondering the same thing.

I have both and it was not to bad getting it set up.
I put in the RR first and then found out my stock pump was week.
Just set the regulator on the RR a few psi lower than the pump, that in what Dennis told me to do and has been great for over a year.

yes the fuel can only be regulated at one point so whichever is set lower is where the pressure will be regulated. there is no need but it will work fine

When you say no need, I'm thinking your talking about rr. How do you cure the dead head in the fuel rails. I don't want to starve injectors at back of passenger rail so that's why I thought rr and get rid of stock riser so I don't have to buy fuel filter for it. Airdog should do all the filtering I need. Right?

I think if you have bigger injectors a new fuel pump is more necessary than a RR.

Im still on a stock pump 7 yrs later, and ran 190's with my stock pump for 3 yrs. Added the RR 2 yrs ago, then added the Airdog 150 few months ago.

Yeah the Airdog filters down to 2 microns. You can just do a crossover on the back of the heads to keep from starving the back injectors. You can just remove the stand pipe from the filter can and Viola, no more filter needed.
