I have one but I haven't installed it. My mechanic didn't want to. If it's properly installed and a good design, then I think the main worry would be vapor lock :

Vapor lock - Wikipedia, the free encyclopedia
Quote:
It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
But, from what I have read on wikipedia, vapor lock is more of a low-pressure fuel-line carburetor issue than a high-pressure fuel-injection issue.

Here are some fuel ignition comparisons :

Ignition Temperature of Gasoline
Code:
The minimum ignition temperature at atmospheric pressure 
for some substances are: 

Carbon          400 C =  752 F 
Gasoline        260 C =  500 F 
Hydrogen        580 C = 1076 F 
Carbon Monoxide 610 C = 1130 F 
Methane         630 C = 1166 F
Question: What would the ignition temperature be at modern fuel injection PSI?!?!?!?
