It's the secondary air injector pump inlet hose

I crossed the number in your pic to
F5UZ-9S449-C
Sorry but Ford has discontinued that hose.
I'll try to scan you a pic from my parts catalog tonight

Air injection, hilarious concept auto manufactures had, reminds me of the heaters from early vehicles, the exhaust was run inside the cabin, no one complained of being cold for long.

I have seen on ford forums where people have bypassed that pump...Is that a wise thing to do?

Volkswagen anyone? LOL!

How about the early Corvairs with gasoline heaters? Yikes!!!

If you live in a state that has inspections, you don't want to bypass it as the van will not pass.

I removed the air injection entirely.
The 5.8s in the E250/E350 didn't have it. They ran a idler pulley in place of the pump. That's were I got my pulley and just removed the rest.
There's no visual inspection during emissions testing here and the old Ford passes just fine without it.

Picture of the pump replacement idler:

Edit: Ken's right, if where you live, they look to see if the factory equipment is in place as part of the inspection then it has to be there.

Thanks for the feed back!

We don't have inspections down here...yet...

I guess i will leave it on until it dies. i don't know if its close to poopin out but the pulley looks a little wobbly..I don't hear a grind or any thing. I have priced them at around 75$ new online.

Do you have a catalytic converter in place? If so I'd leave the air pump on. Working in conjunction with the catalytic converter an air pump reduces hydrocarbons and carbon monoxide in your exhaust. Without a catalytic converter, an air pump would serve little purpose...

Despite opinions you'll hear in abundance, an air pump only consumes about 1 Hp. As an example to compare this against, common vintage air conditioner compressors might consume 8-15 Hp. Unfortunately my Dodge is in the 12-15 Hp crowd with my antiquated RV-2 v-twin compressor... modern 3hp rotary or scroll compressors like a Sanden are in my dreams!

People who claim magical improvements in performance by removing air pumps typically removed them and a bunch of other parts at the same time when they had far more serious problems and were casting about for solutions which they could do in a hurry and on the cheap, like removing things they didn't understand or couldn't test properly from the engine.

Thanks for the info! I do have my cat in place. Its crazy that older ac compressors take up that much hp!

??
I didn't think I claimed any horsepower gains........?
I removed the air pump because the bearing was bad and the piping had a hole where it met the exhaust pipe. The van passes emissions here with flying colors even without the older vehicle allowance (it's an '88). I think a vehicle with EFI/EEC gets very limited emissions benefit from the air injection anyway or so I've seen (based on the years it has tested before and after).
