It has a rubber vacuum line going to the end of it. It should have a clamp and pinch bolt holding it to the fuel rail. It looks like a pretty easy swap. Just make sure to depressurize the fuel system first. __________________ Vince Carknard 1995 318ti Active Hellrot, 16" 5 spoke, "Fogged" airbox mod, Stromung exhaust, Bilstein Sports, BMW sport springs, 3.73lsd, others... | | | 03-22-2005, 12:00 AM | #6 | Member Join Date: Nov 2004 Location: Georgia Posts: 31 | will i need to take off my intake manifold to replace it then? | | | 03-22-2005, 04:26 PM | #7 | Senior Member Join Date: Jul 2004 Location: Tampa Posts: 465 | link us to the cosmo page to get the regulator for an S52 please. | | | 04-11-2005, 01:05 PM | #8 | Member Join Date: Mar 2005 Location: Rimini, Italy (Europe) Posts: 73 | __________________ I'am italian! | | | 04-11-2005, 02:19 PM | #9 | Senior Member Join Date: Jul 2004 Location: Florida Posts: 1,595 | Quote: Originally Posted by mightymax alright i have had my fuel pressure regulator that i bought from cosmo racing for like 3 weeks now but there directions suck so bad so i was wondering if there was anyway somebody could give me a pic of where the stock fuel pressure regulator is and any other useful infromation about the install. thanks | Have you installed it yet? Any gains? | | | 04-11-2005, 06:16 PM | #10 | Member Join Date: Nov 2004 Location: Georgia Posts: 31 | i havent installed it yett, had some trouble figuring this stuff out to be all honest should have it on by this weekend ill tell you then. | | | 04-23-2005, 11:24 PM | #11 | Senior Member Join Date: Jul 2004 Location: Florida Posts: 1,595 | Is it on yet? Thinking of buying one soon. | | | 11-04-2005, 11:28 AM | #12 | Senior Member Join Date: Aug 2003 Location: cary, nc Posts: 2,259 | resurrecting an old topic, yes... but also curious as to what a fuel pressure regulator does...other than regulate fuel pressure...does that give you gains and such? anyone else got one yet? just surfing the net and saw one and was thinking about what it does and how it works __________________ 1995 318ti Active Pioneer Speakers [] Aluminum Billet door locks [] ACS Pedals/Deadrest [] ACS Shift Knob / E-Brake Handle [] Clear Corners/Tails/Sides [] Sylvania Exterior Lighting [] Custom CAI [] Dinan Engine Chip [] Dinan Transmission Chip [] H&R Race Springs [] Tokico Illumina Shocks [] BMW X-Brace [] Relocated Lighter Mod [] Custom iPod Mod http://www.cardomain.com/id/robcarync | | | 11-04-2005, 10:39 PM | #13 | Senior Member Join Date: Jul 2005 Location: UK Posts: 312 | taken from http://www.fuelsystem.co.uk/pbv.htm Quote: Ref: Original Equipment Fuel Pressure Control Valve The electric fuel pump supplies fuel at a high pressure to the fuel rail and injectors, which is then regulated by a fuel pressure control valve. Typically, the regulator is not adjustable and is pre-set to a 3 bar maximum pressure. At idle the fuel pressure valve reduces it by 0.5 bar approximately to 2.5 bar. When accelerating quickly from standstill the fuel pressure increases at a proportional rate retaining a lean fuel mixture strength as required by the E.E.C. for new vehicles. However, the resultant effects of the standard valve produce: lethargic throttle response occasional drivability problems at slow traffic speeds intermediate performance 'flat spots' when accelerating By comparison: Ref: Power Boost Valve (replacement) Firstly, this valve has an adjustable fuel pressure, effected by the movement of an adjustment screw on the crown of the unit. New Power Boost Valves are pre-set with a maximum fuel pressure of 2.5, 3.0 or 3.5 bar, depending on the vehicle in question, and similarly (to the original valve) the fuel pressure is reduced by 0.5 bar approximately at idle. There the similarities end. On acceleration from standstill the Power Boost Valve fuel pressure will increase at 1.7 times the standard rate. This will produce a healthy, strong fuel mixture strength which will instantly improve the drivability of your vehicle, providing:- instant throttle response removal of performance flat spots faster acceleration extra engine performance The regulator enhances engine performance on acceleration by enriching the mixture strength. On constant throttle and cruise conditions the valve returns to a normal regulator function. | | | | 01-11-2006, 02:41 AM | #14 | Senior Member Join Date: Oct 2004 Location: Tennessee Posts: 523 | I know this is a few months old, but #1 does any one know if this is worth it? #2 If you were going to purchase one would you go with cosmos for like $120 OR bmp designs for $250? __________________ | | | 01-11-2006, 02:46 AM | #15 | Senior Member Join Date: Jul 2004 Location: Florida Posts: 1,595 | Quote: Originally Posted by 1rstbmw!
