i need the fuel to go down. i turn it counter-clockwise but my fuel is still staying at 50 psi. how much do u have to turn?

 

If you got a B&M fpr then NO you cant adjust it down..

 

the diaphram goes bad in those all the time.

 

it's not a AEM. i'm not sure of the brand. it's purple. came with my car.

 

B&M for sure. Do you have a fuel pump as well?

 

B&M come purple, and those are no good. You can only go up with those not down. You need to find a true fpr with 1:1

 

Meh. I can go down with my B&M.. Down to 20 with my walbro if I wanted. Then again. my B&M seems to defy all laws of physics when it coesm to B&M being shitty and having little control.... lol

 

So you cant turn it down under 20.. I guess its your car use what you want. I just know there junk

 

I haven't tried gonig past 20. no one needs to go taht low lol. I am always in the range of 40-50psi anyways. And yes I agree. they are junk. lol

 

yeah, i do have a fuel pump. it's a walbro. any help?

 

You can turn down a b and M if you drill a small hole in the bottom of the regulator to relieve pressure...with a fuel pump you shouldnt be able to lower it greatly unless the regulator has been drilled...

Yeah that's generally the truth. I've only heard of a few stories where ppl can still bring the pressures down quite a bit. mines included without drilling

But that's most likely your problem. you got a walbro pump. too much rpessure for that stock regulator return.
