I'm working on making my truck as waterproof as is possible and I'm now looking at extending the diff breathers up into the engine compartment. Anyone done this? I'm thinking of using some fuel line and inserting the stock breather into it but want to ensure that it not only seals properly but still works. I've heard of other guys doing this but haven't seen it done! Any help would be appriciated.

front breather runs into the engine compartment. If you're standing infront of your engine, look down and to the right of the engine. They are mounted on the right side of the lower engine compartment. I did the rear differential breather, and it's really simple to do. http://www.cardomain.com/memberpage/768241/4

rear:

the front is already raised. If you get into water deeper than that you'll have many more problems than a little water in the diffs ;)

Tacos are nearly impossible to waterproof, good luck.

used the nissan P/N and installed 10' of hose and put a Fram G- fuel filter on the ned in the engine bay
I used a T-fitting and tapped into the front diff breather

Done...

Piece of cake... except that front diff... Fawk that was hard getting my hands in there and the new hose on that tube... I should've just used an extension off of the original front diff hose... :banghead: Oh no I had to have all new hose... Done anyhow... rear diff and front diff to the engine bay as high up as I could locate 'em. Near the fuse box. Not the tranny and transfer yet.. these look like they're going to be like playing blindmans bluff... Anyone have any suggestions before I lose more skin off my forearms? Read the T and T cases have breathers similar to the rear diff. Do they rise vertically or do they have a 90* bend ? Do the fittings need (or can they?) to be changed like the R diff ? Suggestions would be appreciated for an easier way then what I see coming...

hey,

uh just got done raising all my breathers...back one was really easy and the two front ones weren't that bad..hardest part was getting my hands up into there...one hose was 1/4 inch and the other one in the front was smaller so i had to buy 2 sizes smaller than a 1/4 inch...just to let ya know...both easy just pulled off the hose from their union thing and attached the new hose and then put a small hose clamp on em to secure it. pretty much just ran then straight up the stock way and even cliped them into where they were stock but then ran them higher up above the fuse box and zip tied them up there to something...so much fun...tomorrow i put the snorkel on..that will be more work.

for me i just pulled up onto the biggest curb i could find on campus in a paring lot and turned the wheels all the way to the left and i was able to have easy access to the breather lines...given that my truck is already lifted 6" suspinsion...prob made it a little easier too

The smaller of the two hoses coming off the front diff... is that for the ADD? I haven't extended that one yet either... What size was that hose ID ?

Crap I don't have that one... what am I thinking... :banghead:
