Thanks Chris!

I will locate the boost line, check and report back. One reason I suspect it might not be, is that I fiddled with the ignition yesterday, trying to push the lines onto the ignition and the sound changed after that.

If its not the boost line then I will need to remove the ignition from the steering column in order to replace that little part. Is it complicated to remove the ignition? I only see one bolt (in photo) but its attached to the steering lock also, I assume?

Previously I've had issues with small amount of oil in the vacuum line and when I first got the truck, oil was dripping from the ignition. I'm wondering if oil in the vacuum line is causing the hoses to slip off, perhaps?

I actually think I'll keep the boost line. My Madman gauge can read boost and its already there. Like we said, it's not really necessary but since all the parts are there I might as well add one more functionality to the EMS.

Perhaps that cap/plug fell off in your recient fiddling.

There is a small 1/8” nipple on the injection pump’s ALDA vac port (small metal round can looking item on top of IP), that nipple should have the Valium line I’m talking about plugged on. You can just pull the line out of the firewall if you think you won’t need it and plug up that small nipple.

Edit: red arrow is pointing to the nipple you can easily unplug and cap off if that line is leaking boost pressure somewhere under the dash.

I haven't gotten to installing the Snorkel yet. I've just attached the mount for it.

I also changed the air filter yesterday. First time since I picked the truck up from you. It was pretty clogged and I can tell a difference when driving. I'm assuming with the increased amount of air flow I'm going to have to change the air filter more often than before.

I'm happy to report that the problem most likely has been resolved. The cap was missing on the boost line!
