Thanks guys |
If the sound is the HPFP, it doesn't mean it's going bad. Some of them just make that sound.
Here's what I tell some folks:
Yep, that sound you hear is the ultra-high pressure fuel pump. In fact, the engine requires two fuel injection systems to keep up. You see, the engine sits in there, flat, like a Porsche engine and has a really high compression ratio; even calls for gas with a higher octane rating that is found at most pumps.
Why? Because racecar. ..........
