What is the difference between ITP fuel regulated return and Riffraff FRx. I know there is a lot of difference in price. Dont they both do the same thing. Can someone explain the difference between both.

Thanks

 

I personally like the riffraff one because it has the fuel bowl return adaptor.
I just don't like the thought of cutting the return line like some of the other kits.
I'd prefer all hardline and not hose though. I am aware that parke makes some nice hose, I've used lots and lots of it in industry, but I like to build things overkill like most diesel stuff should be.

My vote is riffraff.

 

So do they both do the same thing. Riffraff looks a lot cleaner less parts. Itp looks like its to busy if you know what I am saying . Trying to decide which one to get. If I go with price I would have to go with riffraff especially if they serve the same purpose.

 

I looked quick on the itp Website and couldn't find the frx or cck kit listed.
But I know I've seen it before. I liked the kit until clay come up with his. Then I decided that I'd go with his instead if I were to do it. Now I'm going to do a full reg return and fuel system instead of just the frx.

 

I'd go with clays kit its cleaner and no messinh with a reglator.

 

They do *almost* the same thing. A full RR like the ITP kit or the DFA kit caps off the stock return from the bowl and pushes all the fuel through the heads to the regulator you add into the return line (hence the name). The CCK & FRx use the FPR in the bowl along with a pair of lines you add to the heads to tie it back to the return. They both eliminate the dead-head problem, which is better, I can't say. However, I had the DFA CCK and converted it to their RR. It's nice to have adjustable fuel pressure, especially when you start mod'ing injectors and fuel system to supply them. Stock or smallish upgraded stix probably would do fine on the FRx/CCK. You start getting into large stage 2s or hybrids, then it's time to look into an RR & upgraded fuel pumps, etc...

 

Don't forget also, that a RR system allows you to adjust fuel pressure.

It takes X amount of time to move 135 cc's of fuel into the injector at 60 psi. Larger injectors require more time. So you'll need slightly higher pressure.

 

Okay Joe I plan on doing at least hybrids so I think I will look into RR set up. Would you suggest ITP's set up?

Thanks

 

There not the samething... One is a hose and fitting that ties into the return, the other is a complete fuel system...

ITP sells the best fuel SYSTEM on the market. Period.

 

Thanks I will look into a ITP RR fuel system.
