255 walbro Fuel Pump Install

[adidasdudegst]

Ok, thanks for all the advice and help! It's most appreciated! I will look into getting a DSMlink soon, they are just so damn expensive, with the socketing and everything, I will have to save up...

So, I still would like to put in a fuel pump, sense mine is the stock pump from day 1, So would I be able to install a walbro 255 without having to change the FPR?

you can you will just run rich at idle. if you can swing it it wouldn't hurt to get an aeromotive one they're not that expensive

I haven't had any problems installing pmups without a AFPR but I got them shortly after installing the pumps also. Problems with the stock FPR seem to be a matter of luck. Many people haven't had problems but it seems a limited amount of people have.

There are at least 2 dsmlink setups for sale in the classified section right now for good deals compared to new. Would be better to save your money and install dsmlink first but you wouldn't be the first one to buy it after modding the fuel system.

FPR is a recommendation, not a necessity. Considering what you say in regards to your vehicle funds, I would skip it for now.

I think the old guideline was 14psi stock, 15 psi with fuel pump, >15 psi with injectors and fuel control. I haven't tuned a car without injectors, you may be able to up it a bit though.

Ok, so when I go to buy the dsmlink, does it matter what I choose in terms of injector size? Because right now I have stock, but will upgrade to 550 or 660, depending on what would be a good recommendation for the setup I have...

That is just what it will come with the first time you turn it on. The old 2g DSMLink would lose power if disconnected to the battery, so it's nice to have it at least close in case you don't have a laptop. But I think it retains the settings now without power, so it shouldn't really matter.

YES! so I finally got dsmlink! I'm still a basic user with it, and am trying to research and figure stuff out. so, if I go to a walbro 255, will I still want to get a AFPR, or will dsmlink be the afpr? Also, What is a good set of injectors to get? I'm looking at getting an evo III 16g and already have a ported evo o2 housing.

Get some 1000cc injectors,fuel pump, evoIII 16g and get that bitch tuned on e85.

DSMlink can't control your fuel pressure, so you should still get a quality FPR.

Depending on what kind of fuel you're running, some 660s or 720s should be good enough for pump gas, but if you're running e-85, don't go any less than 950s.
