vacuum

I am cleaning and putting together my intake manifold with a bunch of parts I scavenged. A few vacuum lines in the metal bundle under the intake manifold are clogged. Any one have an idea how to get these cleared?

I picked up my truck this afternoon after having the dealership do the timing belt, water pump, and pulley. When I opened the hood, I noticed the radiator hose was almost "vacuumed" together. I was able to squeeze it, and it was mostly empty. I started the truck later, and it's the same shape. I...

So, my engine mounts are shot. My car is a G spec 200 with a 1VD and manual box. Bare bones, UN spec, but it seems this bring some challenges. The engine mounts on my car are oil filled but have no vacuum tubing. These mounts are only specifically fitted to my spec of vehicle, which is rare...

Hey guys - finally went ahead a did a “rebuild” on my 2f carb. The float valve was sticking amongst other things. I put carb back on and similar symptoms - idle fuel pulling through Venturi. I read in the forum to blow out the idle circuit, likely blocked (with compressed air and carb cleaner)...

Here’s a basic question: When replacing vacuum lines on the HAC valve, the book references Left/Right for the various lines. Is this when the value is viewed from the top, or if looking straight at the ports? This makes a big difference in routing the lines.

Sounds like a couple cylinders. Took all apart and checked plugs are tight and leads are on.could it be another issue? found this hose and don’t know where it goes I guess it vacuum? Second pic shows where it comes from

Hi, could use some help diagnosing an issue on a 2001 with a TRD supercharger running a Unichip piggy back controller. It ran fine for years and thousands of miles, then started throwing codes for throttle position sensor failure, P0120/P0121. My son has been driving it for the past couple of...

Hello, Can anyone point me towards a source for the vacuum diaphragm that operates the secondaries on a 20r Carb? I'm having a really hard time finding one. If no source exists is there a way to repair these old diaphragms? I have a sneaking suspicion that mine failed recently. Have not...

The front plastic cover below the driver sear cushion...how to remove for access? THX

Not sure how to test at home, but 5 minutes after switching off my engine I have no vacuum left in my brake system. Which is a pain in a manual trans. You stop on a really steep hill, leave the car in gear, yank on the useless hand brake lever, get out, do whatever you have to do, then to...

I took what I thought was pretty good pics of how things were prior to disassembling everything. Apparently, I didn't get good pics of where this vacuum line went. This is on a 1973 FJ40. I have narrowed this down to going to the charcoal cannister on the passenger side. From the other pics...

Hey all! Read through a ton of posts the last few months and learned a ton. Hoping to describe my specific problem and see if anyone has any pointers outside of everything I’ve been searching. 1986 FJ60 (fully smogged). Bought as a non-runner, though it would crank and start, just died after...

Was swapping vac lines for new. Maybe 30% done. Suddenly she stumbles taking off in first, when she didn't before. Vac Leak seems most likely. I was banging around alot of those old hoses. Runs okay once there is, a bit of inertia. Any obvious parts of an 82 system I should check for leaks...

Greetings, I have a custom vacuum switch in my 65FJ( photo). Yes it’s very old school. The Vacuum hoses are attached to the transfer case under the FJ. I believe the vacuum system is functional. I’ve never operated a vacuum and want to know how it works. toggle left, 2WD - Toggle right 4WD...

I was working out my vacuum hoses and trying to put everything in the right places, since the cruiser ran like crap. Found a hose missing off the 3 from the intake and then the egr was missing a hose. I got everything lined up and then this part appeared behind my air.....barrel? Question...

First off, thank you, MUD community. I've searched through multiple threads for solutions to various problems, and because of the wealth of knowledge here on MUD, I have been able to find the answers I need to fix the issues I have encountered. I have never needed to post a question myself...

I've been removing some aftermarket antenna stuff (am/fm and uhf cb) from my 80 today and got curious about the vacuum setup that is used with the brake booster (no clutch booster on Oz 80's). I've never seen any sort of warning light show up or any sort of buzzer making a noise, so I'm not...

I had read that de-smogging would result in only moderate gains in performance, but the job I did today made a huge difference. I suspect that the real game changer for my rig was the removal of so many vacuum related points of failure. Many of the hoses that I pulled were clogged or corroded...
