I'm curiouse .. what does a fuel rail do .. and is it easy to install ?

 

It just supports more fuel flow to your injectors. It's not that hard to install just remember to lube the injector o rings with a little oil beffor sliding them back into place.

 

wut if u didn't lube the o ring then wut??
will it leak??

 

no but u risk tearingthem.

 

Does it help or hurt anything to put this on a farily stock motor? like no other fuel mods, no turbo etc...

 

yea always lube them cause i tore one and that sucks ***. gas gets sprayed everywhere. i was lucky that it didnt catch on fire.

 

it's not needed unless you have large injectors... large injectors can empty the fuel rail and thus needeing a larger aftermarket one..

unless your turbo or supercharged andputting out 350-400 hp. i think ou should invest your money in some cam gears or some flowers for your mom.

I have one just because i needed to add a fuel pressure gauge... and it has a spot for the regulator AND a fuel pressure spot..
