Replacing 3FE vacuum hoses

[Otter]

Just thought I would try and help someone else out that might be in my situation.

I just finished replacing all of the small vacuum lines on my 1991 FJ80. After doing some searches on how much vacuum line I would need, I ordered 20 sets of the Toyota Vacuum line part #90999-92003. These lines come in 600mm (@ 23 in.) segments, since it was $1.71 per piece, it was @ $0.85 per foot. This was cheaper than the McMaster-Carr option.

I followed Jon Held's advice and cleaned out the hard lines as I went. Some were completely blocked. However, a can of Throttle body cleaner worked perfectly to help me trace each line and make sure it was clear. The spray tube fits perfectly in the hard vacuum lines.

After it was all said and done, I only used 12 vacuum lines. I was pretty frugal, and tried to make the most from each cut. I had read where some suggested 30 or 35 feet of hose, so I wanted to make sure I had enough. In total, I guess I used about 24 feet of hose.

After finishing, I can definitely say the Cruiser ran a lot better.

Not sure how this might carry over to the 93 and up FZJ80s, or even the FJ62s with the 3FE.

I've read several threads on this. But, I'm still not absolutely certain. What is the recommended length and inside diameters of the vacuum hose needed to completely re-hose a stock U.S. spec FJ62 3F-E with emissions?

simple format:

I recommend XX feet of X.Xmm i.d. silicon hose and
I recommend XX feet of X.Xmm i.d. silicon hose

(I believe the inside diameters are 3.0mm and 5.5mm. Correct?)

any auto parts store has what you want in bulk. just bring hose to parts store and they should have rolls of it, and give you whatever length you need..

 

[ATXFJ]

I just realized I'm in the 80 series tech section. Well, I think the 3F-E is the same in the FJ62 so...

 

[Otter]

Most of the threads I've seen say 30 feet of the 3.5mm and 10 feet of the 5.5mm.

Toyota sells 600mm lengths of the 3.5mm, but each of the 5.5mm lines have their own part number.

If you look around you'll see corresponding part numbers for the 3.5 and 5.5 lines that can be ordered in bulk from McMaster-Carr. However, I found that the OEM 3.5mm lines were cheaper (per foot) from Toyota. It was less than a dollar per foot.

I doubt that it matters, but the OEM 5.5mm lines were not made from the same material as the 3.5mm lines.

 

[Otter]

Yes, the 3FE is the same in both trucks.

Thanks Otter! I read a lot of confusing threads with different inside diameters... They were only .5mm discrepancies, but I wanted the exact size. Thanks again!

 

[Otter]

No problem. I read all of those threads also and had a hard time determining it myself. That's one of the reasons I went with OEM instead of finding a comparable replacement part (i.e. - McMaster Carr tubing). Plus, since going through CDan or one of the other Toyota parts guys, OEM was cheaper.

Otter, great write up. I already picked up and replaced all cooling hoses from CDan, now its time for all vacuum lines..

Happy holidays

I need to do all my coolant hoses. How much did that cost you??

I dont have my receipts, IIRC about $200 or so for hoses.. I went OEM with the PHH. Call CDan or Beno they are very helpful. I also replaced t-stat, Fan clutch(blue) and AC condenser in the same deal..

Howdy - Anyone have a preference re: silicone or rubber? Had a tech tell me rubber will hold better, silicone resist heat better. I have issues with the rubber slipping off various fittings occasionally, but most likely because they're old and hard. Also - brand? guy said Goodyear was always best, but it sounds like maybe i should stick with Toy parts counter.

 

[Otter]

I used the oem ones. Didn't have to worry about finding the right size. Cut the sections to length and you're good to go. Mine are still in great shape.

 

[Patty Whack]

Thanks for the input. My Toy store here in Kona tells me they just buy all their tubing by the roll from NAPA. great. naptastic. Any good, reliable online OEM distributors?

 

[Otter]

Any of the guys recommended on the 80 forum are reliable: Dan, Beno, Etc. Look them up for their contact info.

 

[Patty Whack]

Aight den. Thanks for the info.

i went with some rubber cotton overbraided fuel hose with some heat shrink i had to keep ends tidy also tried some 3.5mm silicone hose silicone is only good for air box 3 hoses it slips off on the hard lines elsewere also to make fitting easier to get rubber hose 2 slide on easily and grip good use a bit off cheap hair spray silicone hose rest that wouldnt grip to hard lines was used for a balance line from lpg converter and up snorkle pre sensor to stop stalling at traffic lights.

Thanks for this info! I was looking everywhere for how much I'd need of the 3.5mm hose. Now I'm confused by the 5.5mm hose. You say each hose has a different part? Do you know any of these part numbers or could I just buy a bunch of one part number and then cut to fit?
