vacuum

So I recently lost the timing on my 40, but realigned it, BB lined up and she actually starts stronger than before. Problem I'm having now is when I attach the vaccum advance and hit the throttle she stumbles like a drunk bridesmaid with one heel on. Any advice?

I fitted a used brake booster to my bj74. I also plumbed in a second vacuum reservoir for the brakes. With a vac gauge on the small line that runs to the vsv, it takes about 8 seconds to make 25 in. Hg The booster has two diaphragms so each time the brake pedal is pushed, a lot of vacuum is...

Hey all, Like the title says, whenever I'm cranking up my fj60 (with recently rebuilt engine) I'm hearing a burst of air coming from the engine. Also, when the engine is warm and I'm anywhere about 2000 rpm, the engine starts stuttering/hesitating causing the whole truck to jerk back and...

hello everyone i just finished working on a 1hdft, now need help with the vacuum lines this is a non EGR system, i have searched a lot couldn't find anything :/ a disgram or picture would help loads! thanks in advance

50ft of 3mm + 12ft of 6mm, boyish good looks, and no idea what I'm looking at or doing, I set off to replace all my vacuum hoses as many were collapsed or already split at the ends after I stopped by the shop on base to see if they could help me figure out why the truck refused to idle and died...

Hey folks, I finally got Babe pretty much put back together and installed a new gauge pod over the weekend and started running some diagnostics because she seems sluggish. Here is some quick information on what I've done to her (that would affect the numbers) I live at 9000' 33"x12.5 BFG AT's...

Does anybody know the P/N for 5.5mm ID vacuum hose from Toyota, assuming this isn't NLA? I've bought a bunch of the 3.5mm ID in 1 meter lengths through P/N 90999-92004. You can also get 2/3 meter lengths with part 90999-92003.

I'm putting my engine tiger after doing a head gasket. I have a leftover hose. In my teardown, I labeled it as FSM step #44-48 which is right around removing the cams. I called it "head vacuum hose". Now I can figure out where it came from. Does anybody recognize where it should go? From the...

I decided that 1200 rpm for idle was stupid. I knew it was fast, but now know it was 1200 because I finally attached a newly bought fancy-dancy timing light that had an RPM indicator. I also learned it was running at 27 degrees advance. I dialed down the advance by twisting the distributor...

On port "R" of the throttle body.. I would love to know how many inches of vacuum I should be reading at 3000 rpm? The FSM does not specify except to state vacuum. I believe I have something blocking the port and it is NOT carbon. Maybe a broken wire or something similar from a previous...

Hey folks, Some of you awesome people have already helped me a ton with getting Babe back on the road. As some of you read I got her home last weekend from the shop and definitely have some work to do including a mystery fuel leak coming from around the new pick up unit. But that's not why...

Is the "Gas Filter" vacuum fitting thingy (tri-pipe) that screws into the intake manifold a one way air fitting? Or can air flow through it in both directions?

Hey all, I'm looking for advice on how to reroute my late-1980 BJ42's exhaust, and ideas of where to relocate the vacuum canister to. I've got a set of White Knuckle Off Road rock sliders coming in, and that means I can't have things hanging outside my frame rails. The exhaust comes out on the...

I have a 95 Landcruiser with 245,000 miles on it. I'm in California, and need to get a smog check. The CEL came on about 5 days ago, and I scanned it and it said I had a po401 code ("Exhaust EGR Flow Insufficient"). I noticed that the EGR Vacuum Solenoid had a green sticker on it, so I assumed...

Broke mine, looking for a used one.

Well ive read every thing i can find about the common vacuum leaks and I'm still having trouble. I recently installed a trollhole card and dui ignition just because i wanted to update that stuff. And the truck ran as bad or worse than with the stock setup. I finally started finding small vac...

My 72 FJ55 has what appears to be a stock F carb and is running good but I have a few questions about the vacuum connections. 1.) HIGHLIGHTED in RED - I'm not familiar with the vacuum diaphragm on the left side of the carb (what function does this diaphragm perform) ? 2.) HIGHLIGHTED in...

Hi everyone, I finally have a running Land Cruiser again. It's a long story involving a thrown rod and an engine swap (2f for 2f) but here I am. One thing that I have found that is different right now is that I have a terrible gas odor in the cab and eine compartment. I did some inspecting and...

In an attempt to bypass the research involved, I am hoping someone might know a quick link to the info I seek. I'd like to replace all of my vacuum hoses and I'd like to get the correct sizes and lengths needed to do this. I don't want to buy too much and I don't want to pay shipping twice if I...

My 2000 Cruiser has 220K on it and before Overlanding this year, I want to replace all the vacuum lines. Where is the best source and quality vacuum hose? , other than ordering all the individual ones from the dealer. Curious what everyone is using and if they are happy with the quality...
