Text Box: Below is our RECOMMENDED routing of fuel cell vents, and as you can see in illustrations,  This method is fine Even if car is on side,  Does not matter  if vent is on the side of fuel cell or if it is in the middle,  This vent line routing will help prevent fuel spillage. Though I recommend the vent location be on either side of fuel tank or fuel cell, Rather than in middle of cell. I have done extensive testing with these configurations, and with 3 different style roll over valves produced by fuel cell and fuel delivery companies, and have found this to be the best method. Roll over valves ALL have a point where fuel can exit the roll over valve at a given point of cell angle.

Text Box: This is the typical routing of fuel cell vents, and as you can see in illustrations #3  This method is fine UNTIL  (car) is on one side.  Disaster can happen. Does not matter  if vent is on the side of fuel cell or even worse if it is in the middle, If  vent is in the middle of cell can leak on both sides if fuel level is high and car is on either side.

Text Box: Typical vent installation below, Is and has been a normal vent line routing on race cars for years, Due to a recent accident I witnessed, I have made this illustration below for every ones use, The vent lines on the car I witnessed catch on fire after crashing were as typical illustration below. So i came up with this Drawing on Tuesday after the accident on Sunday. We at Racecraft do not vent the fuel cell, That is  installed by the customer or who ever plumbs the car, As I am sure other manufacturers do the same, Though we have used fuel cells in the past that had a rollover vent valve in top of the cell,  After many tests I have came up with the recommended installation below, Though this may not solve the problem 100% of the time, It is a very good way to run vent lines,  NOTE the line must go from one side to the other and then down below fuel cell bottom level.  I researched this on the internet and EVERYONE I could find had illustrations just like the typical installation below, They DID NOT have illustrations of when the car was on its side, and that is what caused the fire in the crash I witnessed,  This is for every one to see our testing on this. Hope this will help someone out. AGAIN we are not saying this is a 100% solution, But this may help,  The vent line on my car was also as typical installation, Until I witnessed this happen, and we have now changed it, after many tests.
