Bulkhead Vintage Air Hose Options

Going to be starting this project soon, was wondering what some of you have done with regard to passing through the four hose lines. I've seen a number of aluminum bulkhead setups (see pix below), just curious if there's any pros/cons involved with any particular approach. I guess Vintage Air also has a grommet setup to pass through. Once the hoses are in place, I'd think there isn't much need to get at them... or is there? Tucking the bulkhead unit up too far would also mean the fender has to come off to access them right?

I would like to try and tuck my hoses up inside the fender area at the rear, sneak them out at the front of the wheel well. If you have done this and have pix I'd like to see them and hear your thoughts. Not a Camaro, but I threw in a pix of what I meant.

Re: Bulkhead Vintage Air Hose Options

I just used one of these. The fewer connections the better imho. You have to use ez clip hose but that was fine with me.

Re: Bulkhead Vintage Air Hose Options

Other than aesthetics... what's the benefit of that $160 piece over just using four grommets?

None that I can think of...

Letís see you apply that line of reasoning to the rest of your build...

Re: Bulkhead Vintage Air Hose Options

[ATTACH]208186Mike Don has a great choice but I went with the square billet unit you posted in your selections. I can send you any pictures you would like of my bulkhead. Mine is accessible without removing the fender and I used EZ clip hose on HP and LP side of my unit. I used Earls super stock on my heater side of the bulkhead. But I understand now you can use EZ hose on both. Just let me know and I will send pictures over or here in your thread for others to view either way.

Re: Bulkhead Vintage Air Hose Options

Iíve used the VA inline on a couple of cars. Tight under the dash an take a little route planning.

My Chevelle uses the oem blower hole and cap similar to the one posted above.

I always use reduced barrier hose. A #10 RB is the same OD as a #8 etc. more flexible and easier to route. I use bead lock fitting. I have a hydraulic bread lock crimper.

Either way I strongly suggest looking at RB Hose

I did opt for the EZ Clip hoses when I ordered. Any/all pix you can spare would certainly be helpful Jon... Thanks!

Don't have a crimper... as noted above, went with VA's EZ Clip option. One thing I was wondering about was whether square, diamond, inline... independent... any particular advantage in these Gen1 cars?

Re: Bulkhead Vintage Air Hose Options

Mike, make sure you get the EZ hose for coolant on the heater side of things. They didnít offer it when I installed my stuff. I have a buddy thatís installing his now and his will be much easier inside the cabin on the evaporator install.

Touche'!

I kinda' get it... you have four (4) fittings per side or eight (8) fittings you might totally eliminate if you can place the thru-firewall plate in the right place. In my case... I'd _like_ to route those hoses into the space between the fender and fender well and pull them out just behind the battery. If I could mount the "port" high enough... say where the blower was, there'd be less chance of kinking the hose on the engine bay side. But... for those who have installed the VA under dash hunk... does that pose any problems with hose/hardline re-direction or interference?

Conversely, using a billet 4-port piece (I think) would allow 90į fittings to turn all the hoses up and into that fender sandwich area. Cost wise... its pretty much a wash as the fittings run about $15 or so each, and those billet 4-port units are on eBay for $25-$45 depending whether its machined or polished.

I've been looking at the VA instructions, and I know this has probably been discussed umpteen times... the engine bay side. Cover with an aftermarket piece or not? My firewall is already black, so I'm thinking about the DSE cover. This might be a '70 Camaro but I guess thats the finished look.



I cooked up an image of Timmy's '69 car when he had it apart, and superimposed the DSE cover over it. Still looking for what the engine bay side would look like with just the parts VA gives you. Also showed the "normal" VA location for a pass-thru connector and the possible blower area location. Interested to hear everyone's thoughts. One afterthought... with the pass-thru up high, that makes for a major PITA any time you have to get at those hoses. And also... if you use any kind of grommet pass-thru like that pretty piece... you have to pull the dash apart to get at the hoses by removing the entire VA unit... right? Ugh.

Re: Bulkhead Vintage Air Hose Options

I used the square VA bulkhead fitting with the EZ Funyuns in my install. Lots of pics in my build thread detailing the install if you need anything specific. I used the DSE block off cover, painted it first before install.

The details start halfway down on pg 87: https://www.camaros.net/forums/56-pro...s-work-87.html

LOL... You failed to tell me that your build thread is one of the most addictive things I've ever seen. OMG... I haven't read it in its entirety... Homeland got in the way... but I'll be checking it out in my spare moments. I did want to ask one thing though. You mentioned at one point you wished you had moved the port a little closer to the fender side... can you explain and maybe suggest the best location? Here I was thinking that the stock VA port would be a fixed location, not something that could be changed by either shifting the entire VA unit or perhaps new plumbing under the dash?

Not to get too far off the topic, but the video at Palmer was really something else. When I was active in the Lightning group we had one of the guys (Ian) who tries to do Watkins Glen every year. PO's a lot of sports car guys off seeing a farm truck lapping them. They don't realize whats underneath the hood or the chassis... he built his own multi-link system, Air-Ride Titanium Shockwaves and more. Spent a gazillion on some custom 3 piece wheels from Germany too. Doesn't drag race... he lives for the Glen.

Re: Bulkhead Vintage Air Hose Options

There seems to be a number of different engine side block off plates, they all seem to look alike except the Detroit Speed is unfinished. The ones from InLineTube and Camaro Central are black powder coated semi-gloss... supposed to be close to original. Camaro Central sells theirs for twenty bucks cheaper than the DSE, InlineTube, or or VA ones. Anybody have any experience with the powder coated ones?
