Ok im not gonna lie, i got myself a new fuel pump and have no clue on how to install it. My genius friend cant even figure it out. Can anyone supply instructions on how to take out the old one and install the new one? Also, any things i should check for in my old one to see how bad it really was?

 

bad fuel pump could also cause lean fuel mix by n e chance?

 

lean air/fuel ratio's can be caused by bad O2 sensor, clogged fuel filter, bad fuel pump...
why r u change n ur fuel pump?

 

bad fuel pump is probably the case.

Wow thats incredibly easy. Why was i thinking the gas tank had to be dropped? Im ordering my pump tomorrow.

 

all ready changed o2 sensor, bought me a new fuel filter, next is the pump. I need to change it because i have cold air intake on the way.

 

you're changing your fuel pump just because you're getting a cold air intake?

are you serious? unless it's bad, leave it alone... depending on how much fuel your fuel pump will flow, it can and will overun the stock fuel regulator if your lph is too high.

get an adjustable FPR

 

lol, ya your intake won't allow all that much more air in, stock runs really rich anyways so you don't have anything to worry about,

on the other hand, there's nothing wrong with preventative maintenance, but like the guys said get a FPR if you need more fuel, the gauge can also show you if your fuel pump is working ok

 

my fuel mix is running lean. Too much air not enuff gas. I'm gonna take a look at my pump to see if it needs to be replaced. If not i would just leave the thing alone... however my car is being a pain in the *** to accelerate because its not getting enuff gas. Plus when i sit under half a tank and hit the brakes hard, my car shuts off... so im having a fuel line problem.

 

check your timing?

 

I've installed pumps on several occasions. It's not that hard, just lesson the fuel pressure so you don't have fuel spewing everywhere when you unplug the lines. I don't think the fuel pump is going to give you any warnings that it's bad, I think it just dies. I wouldn't change the pump unless it dies. For your lean issue, you might want to make sure there's correct fuel pressure, fuel filter is good, & injectors are good. If the fuel pressure is correct then the pump is fine. Maybe get a fuel pressure regulator to increase pressure?

 

you know you can buy a fuel pressure gauge for like 10bux?

put that on there, start the car, if the FP is holding well then your pump is fine, simple as that! if you think you're lean then buy a FPR for another $40 and turn up the pressure 2 or 3 psi.

don't waste money replacing a pump that's probably fine.

-edit just realized you already bought the pump, oh well

 

I'm really car illiterate... i returned the fuel pump got me a regulator instead... now how do i go about increasing the pressure?

 

i hope you got a gauge with that regulator! otherwise you have no way of knowing how much you're raising the psi, don't worry though gauges are like 10bux

basically the regulator should ome with instructions, but i'll break it down for you,

step 1 - install the gauge
this involves undoing the lines running into your fuel filter and attaching the guage. the fuel filter is found on the passenger side, in the back, mounted against the firewall. install gauge, start car and look for leaks, note your STOCK pressure, remember this

step 2 - replace the stock regulator, with your new adjustable one
the FPR is found in the drivers side, attached to the fuel rail. basically you take off the stock one, then follow the instructions that cam with your regulator, the only hard part is when you have to saw your stock regulator in half, and re-use the bottom half, i used an angle grinder to saw mine, a hacksaw would work too if you have a vice,

once it's all installed, you simply turn the little nut on the top opf the FPR, look at your newly installed gauge and you will see your PSI's rise,

 

btw, a shop would charge maybe 30-45minutes to do this, so you can always do that
