on my 2wd cossy just near the fuel rail for the injecters is the fuel reg ,on the top of it a presume theres a cap missing if i put my finger over it you can feel it sucking is ths normal.also on the turbo side the manifold that bolts to the engine the bolts were loose.

Personally I would change it as the fuel pressure will be low on boost if the seal has failed.

thanks for a quick reply stu

do you just swop it over or is there more to it.

Stu @ M Developments

Your welcome.
You could risk just sealing it up, but if it ever fails flat out you could lose an engine. Fuel pressure is not something I will ever take risks with personally.

ive been driveing round with it like that since i bought last week glad i asked now.

Stu @ M Developments

Hmm, this is where your problems arise.
The fact the reg was tampered with suggests you may be running non standard fuel pressure. If thats the case, running standard pressure with a nice new reg is going to leave your fueling either rich or lean, and theres no way to find out bar testing it.

its stage 1 so it probaly will of been played with should i just cap it for now what do you suggest.

i would get a new standard one on there and then get the map checked and tweaked as necessary

saying that i have noticed the cars lumpy when cold on a morning also the back box of the inside of exhaust is realy black.it was mapped by powerstation but that was a while ago,

I might be speaking out of turn but to save heartache, I'd suggest taking it to an expert for a setup with a new regulator.

were do you get them from

i will get it set up i live at stockton so were do people recommend.being is it safe to drive far.

i see now thanks carlo

They come in all different pressures with it only being stage one surley one of them will do? obviously still be better being checked

Stu @ M Developments

iTrader: (12)

Yes mate, that is the reg we would replace it with were it to come here.

Nice one prob solved

tabetha

There is a tiny amount of suction felt here when the plug is removed, via the threads, but is seriously small

mulla

iTrader: (1)

yeah its only very small the cap missing ive just plugged it for now seems fine

tabetha

It's so miniscule, I didn't bother doing anything with mine, was mapped like that perfectly too, if I plugged the hole now the change would be too small to detect.
The std pressure eg has TWO diaphragms inside, both connected in thier respective centres to the pintle(valve), amazing what can be charged for such a simple to make device.

With respect, it is VERY unprofessional to map a car knowing you have a fault with a critical component.
It could fail a fraction more and lean of the AFR without you knowing until you have molten alloy in the sump !

A small leak at idle giving a small effect has a larger effect on boost as the regulator is a multiplier device.

You always seemed switched on to me which makes it even more surprising that you think its ok to run the car like this !


Yes it is a simple device but it is not something you could make yourself for the same amount of money/quality/time you would buy it for.
Lets not forget, it is a piece of precision engineering that is tested and calibrated.
