if i have a 45dcoe can i keep the stock fuel pumd and jus get a holley fuel pressure reg and what does the pressure reg have to be set at(how many psi)

I used the stock pump on my 48 IDA's for quite awhile with no problems. When the stocker went out, I put on the Holley Blue w/reg. If I remember right, I think it the reg was set around 3.5 lbs.(Not real sure though)

for weber is 4.5psi on stock https://www.nopistons.com/forums/pub...#>/biggrin.png

I have my side draft set to 3psi. If you are using a dead head regulator, you need to set the pressure while the engine is running.

I heard that pump is supposed to be loud and sound similar to a garbage disposal. https://www.nopistons.com/forums/pub...IR#>/smile.png

the holley blue is very noise

Yeah, it was loud. Definately wouldn't wonder if it was running or not. https://www.nopistons.com/forums/pub...DIR#>/wink.png

my friend had a bp rx3 with the holley and you could clearly hear the fuel pump
