Going to be popping in my SARD 800s next weekend (Ok will be paying soemone else to do it

Anyone done thsi before and know what has to be removed? What new washers - O-rings or gaskets I will need?

JP,

I'd deffo have a go at this myself!

Let the car stand for a while to allow fuel pressure to dissipate, unbolt fuel rail and remove. Unbolt injector clamps and simply pull injectors free!

Take it the new Sards have the O rings? I would also put in a new set of seals/grommets on the end of the injectors...

The seals/grommets seal the end of the injector against the head

Edited to make sense!

kris, tis being done at same time as turbo. hence i cant be arsed infact i will probs be assisting in this when go to collect the car as ecu will require major adjustment pre starting

what are seals grommets? is this like your cats lipstick?

sards do have two off o rings per injector already installed. Not sure what the other bit you are talking about is TBH

JP, I presume you are not trying to run the Sard 800's off the stock fuel pump and fuel pressure regulator? I'm sure you have all this sorted but I'd be interested to hear what you've fitted?

Don, I have a uprated pump - It was a sytec jobbie (which i sthe same as the walbro) this has been fitted for a year now. WRT the FPR - I am still running stock - TBH I could never understand the reasoning behind fitting an uprated one - setting teh base pressure to standard and it being a "rising rate" at the same rate as the standard FPR. Some supplied items are apparently like the power boost valve FPR that have a rising rate greater than 1 which has caused fuelling issues.

If you know of any issues with teh stock FPR let me know- The stock rev 3 fuel rail I also seemed to remember was fine at the kind of level I am likely to be running at. 350 ish bhp?

Cheers

AFAIK the stock FPR is not adjustable so if the 'rising rate' is incapable of keeping fuel up to the 800's then I'd have thought the 800's could run lean. The pump may be more than capable of supplying enough fuel but the higher the pressure the lower the flow assuming all other factors are constant. The precise dynamics are a bit of a mystery to me so that's why I've got a fuel pressure gauge on my Starship Enterprise dash. At least I'll be able to see if the pressure drops off under high boost then I know I need to fit my Walbro and/or FPR

There's some useful info here http://216.242.145.16/products/content_p.phtml?pk=69

Don,
From what I gather it is a lot more important that the fuel pump can maintain the flow at the pressures required. the FPR allows a mild tweaking of the fuelling level - The FPR is nothing more than a pressure valve, a popular mod for "non-adjustable" FPR's was to put them ina vice and squeeze them to up teh base pressure.

I cant see why I woudl need to change the FPR and then just use the stock base pressure as most suggest. As long as the pump flows enough and the injectors can bung enough fuel in and I can control it with teh Power Fc I am hoping the job will be done. I think I woudl actually be more tempted to twin feed teh stock rail than change the FPR. TBH I dont know a great deal about FPR's part from I looked into swapping ;ast year when I fitted teh Sytec and no-one could give me any advice as to why, what and which then. The only thing I learnt was dont get the 1.6X rising rate, set base fuel pressure to stock with stock ecu, and get a bling Sard FPR. Maybe I missed teh point somewhere but hassle and expense for bling just aint my ting.

Pretty sure that the FPR will work just fine JP

The only potential issue you might have is if it can't bleed off enough to keep fuel pressure at the desired levels. Since many have changed to hi flow pumps on the stock regulator this is clearly not an issue

Sorry Don - my posts sounded a little snotty - not intended - lack of sleep seems to have resulted in me having a personality by-pass.

Good call on the fuel pump - standard fuel pump woudl be a bit like trying to blow up a zeppelin with a bicycle pump. running high boost or above 300bhp should be accompanied by a uprated pump.
