vacuum

Shop told me the first brand new alt. with vacuum pump failed, said seal on vacuum failed. Ordered another, same thing happened, oil going in where vacuum is supposed to go. Is there a secret to how you hook this thing up? Are all Vacuum on top, oil in middle and oil out bottom? Do you need to...

So. I did a valve adjustment (nothing was really out of spec) and got a stumble/hesitation upon putting everything back together. drove it once and the new cat was red hot. New noise in exhaust under load (can be heard in the video) (EDIT: would a new cat sound like that??). I even thought I...

Is there anywhere to buy a rebuild kit for the vacuum diaphragm for the 4wd? I'm pretty sure that's what's going on with mine. When the weather is nice again, I'm going to get out there and test it right, but it's just real slow (like hit the button and wait 5-10 mins slow) to engage. I have...

Hey guys. Working on my 5lt franken-engine. Trying to trouble shoot and put back together my vacuum system. Old engine had no EGR system and the new engine had it all deleted. It would help a bunch if I could ID all the parts and know for sure what the truck wants/needs in terms of vacuum...

the part number is 31438-60041. I rebuilt my clutch and would like to hook the vacuum line that goes between the booster and the reservoir unfortunately I lost min...d'oh. Any idea what size it is? It is much bigger than any other vacuum hose I am used to seeing.. Also the one on the turbo...

Running a 1970 (11/69) stock F engine and am going to a Trollhole carb. The new carb only has one vacuum port compared to the three I had before. I also have a vacuum retard distributor with petronix. The FSM (1972 F egnine) actually shows a Vac advance dizzy (page 8-25 or 160 in the pdf.)...

What's this hose for?

Edit October 28, 2020 Hello all! If you are interested in any of the 40 series parts I make please contact Dan at 4WheelAuto and he will help you out. 4WheelAuto is now handling all of my parts essentially as a distributor. I make them and he ships them! Dan is trying to decide what and how...

Greetings, Looking for the under hood vacuum diagram for a 1990 4runner, 22re, 5 speed, 4wd non california. Toyota P/N 17792-3D190 which is no longer available from Toyota.

V8 with an edelbrock carb, PO didn't need to pass emissions but I do. TN 1975 and older are required. I'm close, 7.5 reading on CO (5.0 is allowed). I set my floats, checked my fuel pressure, and have my mixture screws as low and even as possible. New clean air filter 14x3. Now, my dizzy has...

Hi All - Can someone verify that I have my four '70 FJ40 vacuum switch lines hooked up correctly? I have read that the correct line layout is on a figure some where on the vehicle, but I have not been able to find it. Thanks Stoshzack

I am in need of both valves. Rare part having only a one-year-run. Found on both Federal and California Spec'd vehicles. Thanks!

Hey forum! Sooo much awesomeness here! Having an emissions problem. I'll cut to the chase, I don't seem to have any vacuum supply from the main vacuum line that supplies the omissions assembly. It's the line that's just to the right and below the throttle position sensor and comes out of the...

Ok so my 40 is just being terrible. I parked it for a while then decided to do a tune up. So new plugs, points, rotor, plug wires, new "toyota oem" carb from eBay, new air filter... Now when I try to start my 40 it runs then hammers it and then stalls every time! I have tried filling the fuel...

Hi new to the forum, starting a build and have some parts I am not going to neef. I removed all the 4x4 vacuum actuator stuff from my 1970 FJ40. Thought some one might need it everything worked fine when i pulled it 50$ plus shipping Under dash pull handle Cable with good FD knob and vacuum box...

My truck is running like a top, idling smoothly at ~650 rpm, but after doing the 'lean drop' method I've got the idle mixture screw turned nearly all the way out. Doesn't seem right. I have to believe this open vacuum port on the intake manifold, next to the brake booster line, is to blame...
