ive done some seaching and found that there is an adjustable fuel regulator and a vaccum reference pressure regulator. which one is the better?
 
the vacuum refrerenced regulator is adjustable also so it is the best of both worlds.

i am selling one ,if you are interested pm me
 
I have an adjustable FPR. But as said. The vacume FPR is the best of both worlds. Gives both economy and performance. without a bunch of tuneing.
 
I had the JET FPR and it SUCKED just as bad as the stock regulator. You can crank up the FP but then the truck runs pig rich at idle. The VRFPR is awesome. keeps 12psi at idle and boosts it to 18psi at WOT.


Here you can see the VRFPR and the feed line adapter for my FP gauge...

Ok, i'll bite. What does this VRFPR do? Is it an adjustable regulator that also helps richen fuel at WOT? How does it work? How much do these things go for and why are you selling yours?
 
The vacuum refrenced regulator is adjustable . what you do is trun the srcew in the bottom to adjust max fuel pressure. then you hook up a manifold vacuum source to the regulator so at idle ( when vacuum is high) it puuls the fuel pressure down so the truck doesnt run rich as hell. then when you get on the gas vacuum drops and fuel pressure increases when you need it. I have a post in the seller forum with my VRFPR , cusion valve ( gets installed in the vacuum line so the drop and increase in vacuum isnt instant and the fuel flow is gradual and not a hit) and a set of venom high perfomace injectors that flow 10 % more than stock injectors.

I removed the set -up becuase i am now running a 383 and the injectors couldnt support the fuel flow i needed. So i am now running a set of 80lbs injectors with a stock modified regulator set to 12 lbs and a tpi fuel pump.

PM me if interested Joe
 
I like the sound of this reg but can't find it on the net. Any idea who makes them? Thanks.
 
vfpr

thank you for your post. i found the PART# gm17113186 around $62.00 my cost new. how much are you selling just the vfpr? cannot afford the injectors but definitly need them for my engine application.
 
Just watch shipping though...I believe they have gone to a percentage of cost for shipping/handling, which should be better than it used to be, but still seems high. That's how they make their money though.

Still cheaper than buying local for me, my dealers here suck.
 
Okay just a couple quick questions:
Where is the best place to T into for the vacuum?
And is the factory vacuum regulator adjustable?
If so do you need to take the injector pod off to adjust or not?

Thanks

Tim
 
Sounds like this could be a new tech write up. Show install, sources and how it works!
