Some more useful info-exploded diagrams!

External 302/351 diagrams, internal diagrams, and SEFI diagram. Let me know if anyone wants more.

would you happen to have a diagram of the plumbing nightmare of the dual air injection system on 351 outfitted trucks.? It has both the injection into the heads in the back AND injection on the frikkin manifolds also. I've been looking all over for that one.

[grandpaslincoln]

I might, I'll see if I can find one.

Try these. They probably won't help though. I have a few more books lying around, will try to find them tomorrow morning and see if there's some better diagrams.

oh god, that shit. Where I used to work, we had one of those. No converters from the factory, 4bbl carb, two smog pumps and all that plumbing BS. I ripped it all off, truck ran much better.

I can't seem to find the exact setup Enigma. Sorry

What year truck is it?

It's an 89 F-250 (HD) over 8500lb with the 351.
It has one air pump that feeds two supply lines to two air management/diverter valves that supplies 1 line to the ginormous $500 catalytic converter, 1 line to the cylinder head air supply (like on our panthers), 1 line to the right exhaust manifold air supply, and 1 line to the left exhaust manifold air supply.
This is by far the stupidest setup I have ever seen. The Ford engineer that designed this should be tarred, feathered, then shot.
It was messed up when I bought it, and I think I made a good go of it, but I'd like to see a diagram of how it is actually supposed to be. It doesn't need to be functional for me anymore, but the state still requires the inspector to do a visual, so I have to keep it on there. And if it's on there, it might as well be right, you know what I mean.?
I'm going to ask my inspector (he's pretty lenient, to a point) if I can change it over to a single supply like on our panthers, and still pass the visual portion. I would like to run headers eventually, and they don't come with air supply fittings on them.
Much appreciated for your effort.
And for a visual of the nightmare, how about this pic. I took this as I was dismantling everything to do my engine swap over thanksgiving...
yes, the diverter valves are on the top drivers side of the engine, and yes, the air pump is on the standard lower pasenger side. Stupid, stupid, stupid.

Holy crap that's a lot of junk. I'll see what I can scare up on this thing.

The 4bbl ones are worse if you can believe that. The one at my old job was bitched up pretty bad, it would blow fireballs and clouds of black smoke out of the tailpipe. All that nonsense stopped when I de-smogged it. It never left the property, so having it run properly was far more important than getting it through inspection.
