yes that will work, IF your fuel tank has a provision to accept a return line, another way to do it , is connect the fuel regulator return line back to the fuel pressure regulator inlet line, , kinda like putting it back to the tank, avoiding vapor lock etc, thanks
I'll keep that in mind. I'm only using it while I'm running the carbureter. Once I switch over to fuel injection I shouldn't need an external regulator
I have that same regulator to install the same way you did it. I also have a 100 psi holley pump in the tank ready for EFI . That regulator wont bring the pressure down to 6 will it. Holley says it will but now im not sure about that. Lots of other people having your same problem .
That was why I installed the regulator that I did, but yeah...I flooded my carb so bad that fuel came out of every seal...I switched to a lower volume pump and use the regulator to keep the pressure even.
This regulator could not regulate the pressure from an electric pump designed for fuel injection down to a pressure usable for a carburetor. I ended up installing an electric pump better suited for a carb, but I still use this regulator to set the pressure to 5.5 psi
I don't think this was the right regulator for that. Mine didn't regulate the pressure down that low, so I ended up just switching to an electric pump that only put out about 9-10 psi, and used this regulator to knock it down to 6-7 or so, and keep the pressure from fluctuating
That's a Vacuum/Boost reference port I believe...it should be connected to manifold pressure to adjust the fuel being delivered to avoid a lean condition when hammering the throttle
Mine looks identical to this one but has a gauge of 0-100psi. Can you change the gauge to a 0-15psi gauge for easier readings of the low pressures or is the unit actually different to the 0-100psi versions? I mean, 6psi is 6psi, right? Not sure why there are 'carby' models when the other ones start at 0psi also.
I would think you could swap the gauge, but since the unit can go all the way to 100psi I think it would be too difficult to adjust it accurately....It may be best to replace it with a unit like this one that only goes to say 9 psi or so
I dont get how it could work after the carb. I would think by then its too late. since the pressure from the pump is being regulated down before it gets to the carb.
@@halmc8109 Funny, considering the diagram in my thumbnail is taken DIRECTLY from the instructions that Holley provided with the regulator I installed...but what does Holley know? Here is a link to Holley's instructions (Fig 2b to make it even easier for ya)...I wouldn't want you to over exert yourself doing a search, especially since you couldn't be bothered to do a 2 minute search to see if your claims were correct or not documents.holley.com/199r10575rev3.pdf
It does matter if you go before or after. After the carb is always better so that fuel doesn't sit during idle in those lines in your hot engine bay.
That's why I went with a return-style regulator, so the fuel doesn't sit and get hot, it is constantly moving
Good content man💪
Thanks for watching!

I’m suggesting if u have problems go with the 12845 it’s ment for higher out put fuel sistems

Have you got it running with ths carb ? If so is that fuel pressure regulator holding 9 psi?

@@MoonBuiltGarage thanks for the fast reply u gust saved me some time and$👍 what fuel pump u running now?
I picked up some cheap eBay special for around $30 or so...it pushes around 7-9 psi...
I had to run mine in a loop and regulate to the pressure side
What's the part number make and model for that regulator please
Link in the description
hey how did this work out? (gonna check out your vids after this) im looking to run 65psi to 5-6 psi and reviews on everything are so wild

@@MoonBuiltGarage lol yeah that’s what all of the reviews were saying. Seems like you need a two stage to do it effectively. Thanks
i have a bypass12-887 i have a vacumm port outlet on it do that line have to be hook up

I'm not so sure either...but people smarter than me say it works. I just plumbed mine before the carb and that's how I'm gonna send it.
@@MoonBuiltGarage how did it work out
Not sure yet..I haven't gotten my engine back from the machine shop yet

Can you put a fuel filter that comes with a return first , and then put a a fuel regulator after (without) return ?
Show me
I think I just did
