fuel pressure regulator? lol nah man just chuck it out

[slydar]

lol. you give wicked sarcastic advise clinton. its funny cos youre never even on the right track yourself lol.

he said feed...

anyway, the answer is its a "pulsation dampener".

its function is quite self explanatory.

[fixeruperer]

and you dont need it.

and you dont need it.

but it is there for a reason.....

id leave it in if you have it....

also what were you thinking of replacing it with? as i didnt have one on a fuel rail i had, so went down to the local fitting shop and had a very hard timing matching up all the threads. needed like 2 adaptors to make it work. worked out quite expensive. then i found a complete fuel rail for cheap and used that instead....

I originally went to buy a banjo fitting for it and that was a pain in the arse and the guy at the store just asked me what it does.. I have absolutly no idea and apart from fuel flowing throw it I couldn't see any usefull purpose for it so I just got an M12x1.5 to -4 adaptor and then a -4 90* bend.

If the engine will run fine without then it can stay off. cause I honestly couldn't be stuffed trying to find then right fitting for it...

Cheers guys

[Hen may possibly be a nut]

My thoughts too. I kept it until it became a pain to keep. Since ditching it I haven't noticed any issues.
