Title: Fire Extinguisher Lines
Post by: Stan Back on February 17, 2014, 12:37:24 PM

I'd bet that most of you are already doing this -- but just a reminder.  When the bottles are out getting certified, it's a good idea to pressure check the lines to the nozzles.  They can get crushed, or in our case, rusted inside.  We'd had the nozzles at the top of a vertical line, and after lots of salt-washing had introduced water into the system.  New lines along with rerouting so any water would drain out solved the problem.

I have replaced several fire lines over the years, because they were plugged. Much rather find out in the shop than at the 4.

Every time I wash the car I disconnect the fire lines at the bottle and blow them out with compressed air. Just part of routine maintenance.

I blow some Inox spray through them.

Last year I introduced blowing out our lines on Thursday or Friday at speedweek just to be safe. One other thing I notices, depending on Tees and elbows one side might not have the flow that the other will. Could be a serious dealio.

Sorry, I didn't realise it was made here.....cripes, it must be the last thing they DO make here. It's a little heavier than most of the WD40 type things, so it stays there and whether you've been circumcised or not it's safe to use because it's Kosher certified.....true :roll:

For a newbie like me, this is very useful stuff.
We are getting ready to reconfigure the fire suppression system on our Lakester and will utilize some of the comments above.
Thanks much, :cheers:

Has anyone posted pictures relating to line routing and nozzle placement for a fire system? - both engine and driver.
I'm running an inline engine, so are the engine compartment nozzle(s) determined by the exhaust or the oil pan? That is, one nozzle or two.

My understanding is that you should have two nozzles located between the exhaust and the oil pan. So that if you puke out the bottom end, oil splashing on the headers wont start a giant top fuel type fire. But this seems to change from time to time. So you may want to check with the person who is listed for your type of car.
