EMPI 40K Question

[kerian159]

Just wondering if anyone had a diagram or such of the EMPI 40K carbs and could tell me if it has a vacuum port that you could connect a hose to it and test the amount of air going through it to tune it? Just wondering out-loud here.

Ok new question, I'm having difficulty installing the intake for these carbs, does anyone have these carbs on a type iv engine?

You need the correct manifolds and linkage for a Type 4 engine, have no clue what you actually have.

This what I have

Ok sorry was a bit frustrated. Ok. The issue I'm having is trying to toque the middle nuts I can't get any socket or wrench on to it. The intake is in the way.

how about an crow's foot?

Sometimes it also pays to buy cheap wrenches at the swap meet etc that you can saw off, heat and bend to weird angles, grind narrower etc for situations like that. I have several over the years that had to be made for odd nuts or bolts.

Maybe a wobbly socket and extension or a regular short socket with a wobbly extension.

Maybe some ilk of the distributor wrench or bend a box end wrench to work?

Having some old cheap sockets around that you can grind down to make a special tool is a good idea.

Those manifolds are pitifully designed. Completely blind installation on the lower nuts. If the engine is out of the vehicle they are doable but in the bus is a massive pain.

Using nuts that are 10mm across the flats (instead of the usual 13mm) will help a little. Gives you more room to get the tool in the small available space. A mirror may help, magnet tool. The nuts below have a flange which can help. Some sticky grease on a flanged nut and it's a lot easier to get it located and started - the nut stays put in the socket.

The issue with the manifolds is that because there is a web between the runners it's almost impossible to fasten the lower 2 nuts - you can barely see any of what you're doing. The runners belly out and down quite far so they are almost touching the adjacent sheet metal, very little space to work and you are blind. If you were to carefully grind away the web between the runners you'd have a much easier time getting them installed, and I don't think you would weaken the manifolds in a harmful way.

use a hole saw to cut a hole in the middle of the web. That should be quick and simple without reducing the strength. When you cut with the hole saw, put grease on it to help protect the teeth from the heat.

Just think, for several more dollars you could have bought good carbs. What sort of worse problems lay ahead that can’t be seen now?

All good suggestions.

Not that I'm a fan of everythimg at Harbor Freight, but they have a cheap set of crowfoot wrenches for $10.

https://www.harborfreight.com/7-piece-3-8-eighth-i...gJSofD_BwE

They'd be quality enough for this job, and I wouldnt feel bad about grinding the sides down some to fit in there.

The suggestion to have a bunch of swap meet wrenches to grind/bend/cut is a good one. This won't be the last challenge the bus presents.

And just remember the saying ---- "If it were easy to have a Bus, everybody would have one."

Good luck!

Here’s an idea.

Take loose the rear engine hanger from the frame. Remove the two bell housing overhead hanger bolts. Use a floor jack to slightly raise the engine to allow better side access to the intake manifold nuts.

Buy the 8x10 manifold nuts and also a 10mm 1/4 in. Drive wobble socket and
Extension .
You will need it in the future.
Aircooled.net sells them for these type of manifolds

aeromech, yes I could've (should've) gotten a different set of carbs but when I was doing my research these looked like a good set. I did find a video from Kaddie Shack that explains my issues and how to correct them, basically how old DKP driver suggested.

Thanks everyone for your input on this issue
