Installed the B&M fpr on the H22.... i searched and did not find answeres... I was wondering those that have B&M fpr were you able to bring the psi down lower then 43? .... i backed it out all the way and 43psi at idle is the lowest i can get it... my stock fpr was sitting at 40psi steady.. i have a walbro 255 pump... shouldn't the FPR allow me to adjust lower then 43psi? i tried it with vaccum off and on it seems no difference only idle changes....


oyeah i just recently installed A/F ratio meter i knoe its not great but better then nothing, i'm just trying to find out if i'm running rich or lean that was the purpose of the B&M fpr so i can lean it out.... how do you read the B&M gauge when giving it throttle, i notice that it goes as low as 38psi but at idle it would sit at 43..

anyone?

 

With a B&M FPR you will not get lower PSI than stock. I have gotten it down to 41psi.

 

theres a topic on this, drill a tiny hole in the FPR about .035 and put it back together, guess what it worked!!!!!!!!!!!!!!!!! it will go to atleast 32psi with FPR backed all the way out, now i have it set at 38psi idle and without vaccume it sits at 44psi does this sound about right to you guys? is the setting okay for stock h22?


note: those with B&M fpr should check if you have a gauge, when i just threw on the FPR my idle sits at 42psi (walbro255) lowest.... but when i give it a few rev's i noticed the gauge goes lower to 38psi (wtf) if you give it throttle shouldnt it increase instead of decrease? and if yours is anything like mine when you pull of the vaccume line to it the psi does not change ..

Now the hole is drilled for more fuel to flow thru, the fpr i can adjust it more freely from 32psi up, and when the vaccume line is pulled off it would increase in pressure about 6-8psi..... somehow i don't think the B&M fpr functions properly if backed out all the way, thats just from what i noticed from my experience...

Make sure the o-ring is sealing.

No, it does not. It moves away if the spring and cause the diaphragm to move more than it should. You should adjust it in until you see the fuel pressure moving.

 

heres the link...... it really works....took me about 20mins to modify it..make sure the hole is drilled at an angle towards the exit..

you can get the .035 drill bit at a hobby shop there like $1.25 each and i recommend the hand-twist tool to hold that bit its tiny as *****.... i spent about 8 bucks because i baught extra bits and the tool was about $5 bucks

Sweet, did not know that. Keep us posted about how you like it.

well so far it seems to be functioning fine no weird issues and when i rev it the gauge goes up this time working like a FPR should


look good, work good, last long time
