mp62 vacuum hoses diagram: checking for leaks - LotusTalk

sleepe · 10-22-2009, 01:04 AM

I may have a boost leak on my mp62 vf2 setup, but I don't know where to begin looking. Is there a diagram indicating which hoses are the right ones? I'm trying to diagnose hesitation problems.

Not following you, which hoses are the right ones? The right ones for what?
I just finished my VFII install, no issues whatever.
I'm very familure with where all the bits route.

check one of Charlie's threads. He had written up something about checking for leaks.

Concerning boost leak, take a look especially at the coupler at the bottom of the intercooler. (it is barely touching the frame)
Hesitation problems could come from a lot of things too...If you think it's fuel related and your injectors are ok, it might be the O rings at the fuel pump.(it's happened to me)
I assume that you already sealed the gap on the intake pipe housing for the MAF sensor.

What gap?, I didn't have to do this...

The housing for the MAF sensor on my VF II was much larger than the OEM, large enough to leak. But it was one of the first kits, it is probably fine now...
