Default Blow down tube question.

I was wondering how you guys that mounted your bottles on the tunnel mounted your blow down tubes if possible? Thanks.

I'm going to use a 180degree AN fitting and run a steel braided line to my tunnel and use a bulkhead through the floor...If it blows off it'll spray my driveshaft with laughing gas.

i could be wrong but i think there is a rubber grommet under one of the rear seats you can run the line through.

if you are using a flexible line you will need to use a bulkhead fitting to keep the hose from whipping around.

Here is a link to a premade kit to make a AN hose blow down tube...

Not a good idea at all!! I was carrying my spare bottle to the track on the floor, and the heat from the exhaust (through the floor) popped the rupture disc... it was all I could do to get the car off the side of the road and stopped... car filled up with nitrous so fast I couldn't see a thing!!
I will never do that again and can't stress the importance of a blowdown tube enough...

I made a kit out of braided hose like the one Ray posted that's available from Nitro Daves. The grommet I vented through is under the passenger side rear seat. Remove the rear seat (bottom) and pull up the carpet and you can't miss it. I cut a small hole in the carpet and used a bulkhead fitting. I bought a couple of large washers (larger than the grommet hole) and bored them out so the fitting would fit through the washer. It's probably overkill but I put one washer on each side of the floorboard so the bulkhead fitting will never pull out of the floorboard. Everything is hidden once you put the seat back in. I did wrap the braided line where it was against the side of the passenger seat so the metal (braided) tubing wouldn't rub against the leather.

Also, if you have your seat belts removed too, the bolts that hold the female end of the seat belts have holes already drilled in the floorboard and those could be used for the blow down tubes. That's what I am going to use.
