Gup: where is your accel pump boot? I spent $20 to get new accel pump cuz somewhere on forum it said u needed the boot to hold pressure or pump no work? Is boot not needed?

Well damn. That could have bought me a Vito's key!

Mines has the boot but it slides up and down (loose) I don't think it's ment to hold pressure .

Did the mod worked great.

Wanted to add that small spring is located under the brass plunger and that the plunger should move up & down freely.

If it does not move freely then work it back & forth through the hole until it loosens up then you should be good to go.

So what exactly does this mid do?

Better acceleration, I did it and it's actually a really good mod to do

Same here, I just did the mod the other day and to me the throttle is a lot more "crisp" than it was before. Before it was kinda "mooshy" feeling. I did only the spring swap I tried the valve cap but it was way too tight haha.

Another thing is make sure the spring is the correct diameter or it will stick the plunger down, found this out the hard way haha good thing I tested before I reinstalled.
