Walbro fuel pump DIY - Page 3

ShadowFox375 · 11-29-2008, 03:40 PM

Damn, Nice write up man. makes me want to boost my car even more now.

Ainokea_Si · 12-20-2008, 06:54 PM

i am going to be running boost soon, and i want to do everything before the installation of the turbo. could you install the walbro on the stock injectors? i would most likely have the turbo on in a couple weeks after. but want to have smaller installation on that day

good diy.. its very helpful

Supa Ninja · 12-21-2008, 02:02 PM

tony if you run the stock injectors with the walbro its going to run rich, the ECU might be able to trim the fuel down but I haven't heard of anyone running it on a stocker. I recommend waiting with the FP install till you install the turbo and before the tune. It takes less then a hour and is a simple procedure.

Ainokea_Si · 12-21-2008, 02:55 PM

oh ok...i guess i will wait. i am going to start the timer, and controller install soon. get that out of the way

**obert** · 12-21-2008, 04:08 PM

Nice job,thanks for the info.

turktech · 12-21-2008, 06:23 PM

you should be fine running a walbro fuel pump w/o forced induction as it does not raise fuel pressure

Ainokea_Si · 12-21-2008, 09:52 PM

that is one that says it is ok, and one that says no?

1-1 who is next?

can you have a walbro fuel pump with stock injectors N/A?

BigMoney8481 · 12-21-2008, 10:53 PM

it says right on the website that the high pressure walbro is fine with a stock engine

***soxfan143*** · 12-21-2008, 11:24 PM

the Walbro WILL raise fuel pressure on a stock motor. Do not listen to what you have been told. I added the walbro and crushed my FPR with the CT-E tool that comes with the SC and my fuel pressure is at about 95psi now. Way too high. Stock pressure should be around 50-60psi. The FPR crush with a stock fuel pump only raises the pressure by 10psi. With the walbro it went up over 30psi. So don't tell me that the walbro alone will not raise pressure because it will.

Ainokea_Si · 12-22-2008, 01:01 AM

i guess he is saying that it is good for stock, and this one is not...so the score is

2-2.....i just dont know anymore?

anyone else have thoughts?

TRobJunior · 12-22-2008, 08:03 AM

I would goi with what Mike aka Soxfan143 said, he knows what hes talking about, hes been threw alot.

Ainokea_Si · 12-22-2008, 11:52 AM

so that goes

3-2 anyone else say it is safe for a stock n/a?

will the ecu trim enough fuel? i bet it would try....

BigMoney8481 · 12-22-2008, 05:21 PM

ask someone who added the walbro and did NOT crush their fuel pressure regulator

turktech · 12-22-2008, 08:33 PM

if u leave your regulator alone you will be fine with the aftermarket fuel pump.. it does not raise your fuel pressure

psycho1 · 12-22-2008, 09:16 PM

I heard something about having to run a 'closed loop' mod when you install the Walbro FP. Heard anything like that?

Ainokea_Si · 12-23-2008, 12:27 AM

i have heard nothing about that but soxfan is running it in closed loop. this is from his maf clamping having a closed loop all the time

mike07si · 12-23-2008, 06:00 AM

I think you will be fine, especially if you are just commuting until you get the turbo.

Ainokea_Si · 12-23-2008, 12:42 PM

just want to install the little things, so the turbo day would not be held up with little things...like i am hooking up the turbo timer, running wires for the boost controller. and i want to hook up the fuel pump too

Supa Ninja · 12-23-2008, 04:35 PM

Tony don't listen to those guys saying it will be fine, it won't be fine. That Walbro is intended for a fuel system with a return line, in which case it won't raise the pressure. We don't have one so its going to raise our fuel pressure. It can wait till you go boost.

You got to be careful when you ask questions, lots of bad info is put out here.
