just a quick question guys as i need your help.

i have built a 2.1 zetec turbo useing bosch 382cc 803 green injectors


what i want to ask is i currently dont have a fuel pressure regulator on the engine, should the car still fine start without one??

anyone please help

 

You dont have a regulator AT ALL?

If its does run fine it will mean you got very lucky choosing the fuel return pip size

 

no mate.

the 2 pipes from and the return to tank are connected either side of the fuel rail.

i just wanted to know if if would start without a fuel regulator, untill i get hold of one.

just wasent sure if it would stop it from starting?

 

No it wont, unless by some miracle the return pipe is small enough to cause pressure in the rail, but it would be dangerously lean if that happened.

Dont try to start it without a regulator

 

oh ok mate so i take it it wont start without one,,
we did try getting her started but she wouldent even attempt to fire, also we noticed there was a smell of petrol, like it was flooding??

 

Without a regulator there is almost zero pressure in the fuel rail, so i dont see how it could be flooding as it will rely on vacuum from the engine to draw petrol through the injectors.

If it did fire it would run VERY lean, melted piston anyone?

DO NOT TRY AGAIN YOU BODGING CUNT

(no offence intended )

 

chip-3door

PMSL@ no offence intented

 

I'm meant to be more polictically correct these days

 

wouldn't worry mate no else is on this forum!

 

lol no offence taken

we also noticed the fuel pump is not priming, uselly its 2-3 secs before it goes off when ignition is switched on, but we noticed the fuel pumps on constant. guess this might be why because there is almost zero pressure in the fuel rail, could be wrong, but you can def smell petrol once its been cranked over a few time.

(dont worry wont be trying that again till i get a regulator)

unless the flooding is due to the megasquirt setup.

guess im gona need one of these

Personally i would use the Webber one as fitted to cossies as standard.

 

them dial regulators are good as it tells you the pressure, however quite expensive.

whats the webber one like just a small type regulator.

 

agree with chip, waste of money, just use a standard one off a cossie or similar.

oh and if yourte wondering WHY there's zero pressure in the fuel rail, just draw a diagram of your fuel system and you should work it out quite quickly

 

the webber is good enough to go on a cossie so it'll be good enough for your car mate

 

ok, just looked on fleabay this was the only one i could see off a scorpio cosworth http://cgi.ebay.co.uk/FORD-SCORPIO-C...QQcmdZViewItem

this the right one??
if so how do u fit them ass you can attach a pipe one side ok but think other side suppost to fit in manifold. which is no good for me as i have a custom manifold with fuel rail so i need a inline one.

 

No, thats the wrong one.

 

Here is what a standard cossie one looks like:

cheers mate for the picture,

can i use another regulator off a diffrent car as i need one pretty quick and theres none on ebay.

 

please stop tpuching the car until you graps what the fuel reg does



even i can work out why theres no presure


please please please read a little more then go from there

 

potentially as you are mapping it yourself, you can use ANY regulator that is designed to work with positive pressure, so any turbo one basically.

 

ps dont crimp the pipe for presure either !!!!!

 

what do think about these mate

or somethink like a fse

Mate, buy a 2wd cossie one. Soem of that crap your looking at may not be rising rate, thus it will fit and idle, but when you come on boost you will have massive fuelling problems.

It must be rising rate.

 

mate theres a fuel presure reg in parts for sale mate with a plished rail for 40 quid that shorty is selling


sorted

think i got a spare one somewhere too aswell but its in me garage and i try not to visit there

 

thanks b19bal,

i have snt him a pm, i take it these cossie regulators its just 1 pipe from injector rail & other pipe return to tank?

 

yeah and the on epn the top to the inlet manifold

 

cool, am i going to need the cossie rail? as i already have a custom rail, or will i need it for the cossie regulator mate?

 

the cossie reg attaches to the rail with a pipe of pipe on each end so in thory no you dont but i aint seen how your reg is attached

 

b19bal, sent you pm mate.

 

or try any of the breakers, im sure theyve got a few
