I've been trying to complete the PL turbo install myself and I'm stumped. I did some forward research and found a guide from CJM that says I have to modify the pump using drills/files.

To other Walbro owner's... did you have to do this modification to your pumps?
I will be getting a Return Fuel System installed after I get the kit running.

 

Yes I did follow those instructions and they work.

 

That's how I did mine, it was fairly simple - just take your time

 

u need to get a RFS before u run...

it changes the tuning!!!!

 

you certainly dont HAVE to perform the modifications, but it mentions on the how-to what the side effects will be if you do not.

 

I followed the instructions. It's not all that bad, just make sure to buy the right size drill bits.

 

Yep found out that the mods are unnecessary but just recommended.

I am still going to do the jet mod but not regulator since I will be running a return fuel system.

Doesn't seem too bad really.

Just need some dremel drill bits, files, and some patience.

 

what are the side effects?

 

The side effect for not doing the jet mod is a higher fuel pressure.

 

Call your tuner, some prefer that you skip portions of that installation if you're going to run a fuel return system.

 

I called up Function Tuned and they told me that it's okay to just drive over with the stock fuel pump with 600 cc injector's as long as I don't go into boost.

So.. looks like i'm loading up a powerlab 600cc map then basically granny the car to FT for tuning and RFS install
