Air Duct Installation

Has anyone discovered an easy way, other than taking off the fender and or being double jointed, to put the air duct hose onto the flange nearest the driver (LHD)including the clamp.
 
I just did that. I got a short rachet screwdriver at Home Depot($3.50). Stretch tube first (two person job). Remove air filters from carbs. Fit tube form space in front of brake fluid canister and fish it back with clamp attached losely. You then "just" have to work your arm in and tighten everything. It was actually easier than the heater pipes. They were harder to make the turns necessary.
 
Tahoe Healey is right, carefully pre stretch the tubes first, take plenty of pills to relax your self and keep the clamps loose ish and go for it. Not sure of probs with LHD but with RHD and filters removed it was not so bad, a bit tricky I recall feeding the tube in behind the vertical shroud support. The blower tubes are the worst to fit.

Last week I installed a new fresh air line on the port side of the car. Left the air cleaners on and kept the tube "unstreched". Started under the car by the exhaust pipes. A helper "upstairs" would help to guide it but I was able to go it alone. Get it in place, then expand it and put the clamps on. Be careful when expanding, you don't want to scratch the hose on the vertical bracket that supports the shroud (near the hydraulic reservoir). Tight quarters and not a lot of fun, but hey, when its in, sure beats all that hot air blowing in direct from the engine bay

I went through one on the passenger side when I had a neighbor help. He literally crushed it to
bits. I tried my best to keep my composure. I subsuquently ordered another and did it alone. It was a job that sucked but I did get them in. Drivers side was easier. The front one from the heater motor to the front inlet was the worst job, well no, cutting out the rear leafsprings was worse.
 
Speaking of fresh air ducts, does anyone have any recommendations on a way of insulating it so that the fresh air does not pick up engine heat on it travels from the front of the car to the passenger compartment. In the summer time, it feels like the 95 degree ambient air becomes a 150-degree heater blast by the time it passes through the engine compartment. I have replaced the black fabric hose with a flexible aluminum clothes dryer hose. (You’re correct, the installation is a bear) Not an original look, but it helped a bit. However I would still prefer a little less heat pick up. Any ideas.
 
Rob,

I think that the fabric duct would be cooler. Fabric has much less thermal conductivity than metal.I have heard of putting a smaller duct inside with insulation between the two but I don't think that it worked very well & was a whole lot of work.

If you don't care how it looks, just wrap insulation over the outside of the duct.

I once saw a Healey with a very small 12VDC inline blower installed in the fresh air duct. The owner said he got it at a RV store and that it made a big difference. I would imagine that its kinda like switching to the 2nd speed on a hair dryer.

Rob,

I lined my 4" original duct with 3" aluminum dryer duct with a little 1/8" foam duct insulation wrapped around the dryer duct. It keeps it much cooler and doesn't show. The foam insulation is sticky on one side and coavered with aluminum foil on the other.

I know an owner who, on longer trips, would use a vaccum cleaner hose on both sides, wedge it in the side window with one end facing into the wind, and route it down by his feet...I rode with him once. It was not exactly pretty, but it worked great.
 
thanks everyone for your input. i'll give it a try tonight without removing the fender, wish me well. i'm glad to hear that i wasn't the only one who did not enjoy installing the tubes on the blower side. i spent an entire evening working on that little project and used up a box of band-aids to boot. mac

I assume your car is not a 100-4, since the fresh air duct on your car is on the left hand side. Has anyone had any experience installing that same duct on the right side of a lhd 100-4? Attaching the duct to the grille looks like a knuckle buster of a job.
