The only wiring conduit my parts store had was red, in the size that I needed, and I want it all to be black. I remember long ago reading that you should not use black electrical tape in the engine bay and with good reason due to the high heat. What can I wrap this conduit with that will be black and help keep water out? This is for the main EFI wires that run along the firewall and for the distributor & coil wiring as well.

I'm sure the conduit will do a good job but I want to wrap it anyhow to be 100% sure of keeping bugs and water out.

Any suggestions?
 
I've saw a lot of the conduit wrapped with black electrical tape underhood. It should be OK unless you let it touch something real hot like an exhaust manifold or header. I would think that the black conduit wouldn't be too hard to find.
 
i dont know where you read you cant use eclectrical tape, but its find under hood.Just get a good brand so it doesnt get all gummy if you remove it.

ALL...and I mean ALL tape with glue on it will go gummy when you put the heat to it. I think you can buy the plastic wire loom wrap from GRAYBAR electric supply. Why not buy the convoluted tubing? It was availiable years ago in a kit with moiunting brackets, couplers and bridge fittings.
 
Wire wrap tape is very different from electrical tape. I'd suggest picking up the correct stuff. Once you get the wires gummy, it's a pain in the arse to get it clean again.
 
Oh yea, haven't seen that stuff for years. We used that to wrap antenna connectors on shipboard weatherdecks. It streatches a lot. Wraps great, but we coverd it with two layers of regular electrical tape, then a coat of goop I can't remember what it was called. Dried to a flexible seal. Had to cut the whole mess off with a box cutting knife if it needed service later on. Not sure you would want to wrap a wire harnes with it. It would work though. THe stuff we used had a stripe down the center so you could overlap 50% accuratly.

Use that stuff all the time at work but we get it from mcmaster car.

I also got some rubber splice tape from home depot which is pretty nice too, doesnt stretch as much or as easily as the silicon stuff but its a lot tougher(strength wise, im sure the silicon stuff will handle chemicals better).

You can't really unpeel either though, you'll have to slice it length wise then peel it away.

I'm assuming from your bio (I can't fix anything) that you were an ICFA at one time. True? BTDT one. Road DE-1068 in '72. Repaired the HD-HE underway at night while following a Russian cruiser. Look for USS Vreeland DE-1068 cat and mouse games 1972. I was on the gig taking pictures of the Commie Cruiser. Fun times.
 
No, ET surface. Satcomm tech. I never made the ICFA connection...have to change that :) Vreeland Wow. I was the last person off the USS Stark FFG-31-transfered 2 weeks prior. Man, gotta love spec ops.
I just finished wrapping one of my harnesses up with electrical tape. I would rather se something else, but the dry wrap is to hard to deal with. I am pretty meticulas. I pul it tight and overlap 50%. Cut with side cutters and wrap the end with no strain on it. Just prsss in place. It will last a 6 months to a year. Long enough. Almost all the eng compt wiring is n place. Just the Alt left.
 
3M products makes a high temp electrical tape called Scotch Super 33, that I have used on many cars and all of my company's trucks. It holds up to the high heat of the engine compartment. I believe it is rated up to 220 degrees. You can pick it up at Home Depot.
 
I recently used friction tape when I spliced into the existing engine harness, and was kinda impressed. It's the first time I used it, so I don't know the life span of it, or any long-term issues that might show up. It has a cotton base to it so it looks like the old cloth-wrap wires from long-long ago.
