How many of you running a turbo performed this modification. I will be getting my injectors back from witchhunter back early next week and I want to drop them in for some N/A tuning. What I really dont want to do is remove the entire fuel rail to drill and tap.

How necessary is this modification, who done it? I know its a cheap insurance policy but I dunno if its worth the hassle.


P.S. I know your thoughts Chad.

I say do it. The theory is sound, and it's cheap and easy. Plus you can paint your ugly fuel rail. Mine's black.

I am not gonna paint my fuel rail. Unless that has some sort of measurable benefits.

I think it would be pretty foolish not to do it.

I did it before I went turbo and I've had no problems.

I tried to pm you a pic from my office but had to give up on the effort. I don't know how to attach pics on pms.

Good info in those threads. Thanks.

I have but one question. I was thinking of pulling the fuse for the fuel pump and turning the engine over to get as much fuel out of the lines as possible. The How To does not say to do it, but I figure its a smart idea. Yay or Nay?

not much fuel there if you open the gas cap it relieves all the pressure, what you are describing is overkill

Pulling the fuse is a good way to do that. I pull the fuel-inj fuse in the engine bay and crank it till i think it's good. Same deal for when i do fuel filters.

Unnecessary. A little fuel spilling over there will just serve to clean anything on that side of the engine bay... we're only talking about a shot-glass full at most of you pull the fuel cap. Have a towell on stand-by if you must.
