What goes where

Can someone explain what hose goes at every number? Which one in particular goes to the air duct, but would like to know them all. Thanks

I have a later model so itís a bit different.

I can tell you

1 - heater hose to cabin vents.
3 - heater hose to Engine ducts.
4 - connects to muffler.

Not sure about 2.

Thanks Matt. Where you write heater hose to engine ducts, is that also considered the air duct. I'm having trouble getting the thermostat in my mfi to shut off. I read in a post to make sure the hose connecting the air duct to heat exchanger has no holes in it. I'm trying to know which ones to look for, when I return to my mechanics shop tomorrow.

Number 2 is meant to supply heat for MFI

MFI thermostat feeds from the small elbow near #1. The larger #2 is also for MFI, for '72-73 cars (also RoW '74-on with 2.7 MFI) that have the big flapper valve for warm air intake.

Where I have circled yellow, what is that being connected to? Also, what exactly is number 2 connecting to? This is for a 69e, with stock 2.0 Thanks all!!!

Arne, just saw your post. If number 2 also goes to mfi, where does it connect to mfi? All I know of is the smaller supply line of warm air to the thermostat on mfi. Does number two connect to heat exchanger?

Appreciate any and all help.

#2 is not a hose connection. The original boxes were called the street sweeper with an open grill forward bringing hot air to the box on the intake. Lots of dirt and plugged filters.

Yellow circle is a hose connection on my '69 911E. From the heat exchanger to the tin work underneath is a heat resistant hose and from the tin work to the MFI on the top side is a paper hose.

From heat exchanger to tin work with heat resistant hose


underneath tin work. I think #2 is the large black duct in lower right corner of the pic


topside from tin work to MFI with aluminum lined paper hose


Why is hot air routed back into the shroud?

Jeeze I'm an idiot for sure. Just dawned on me that I was getting #2 and yellow circle confused. Isn't #2 the large heat duct to the right in the middle pic above? To the left in bottom pic, large blak duct.

Ken, my mechanic is having a hard time setting fuel rich/lean mixture. He feels the engine is getting too much air. He's trying to dial it in on a dyno with air filter removed and velocity stacks exposed. It's a 69 911E. The mfi has just been rebuilt. Any suggestions as to why he can't get it set properly? I'm about out of patience with this shop.

Sorry I'm no help there.

I gave my engine to Storz to have thier way with it. Even he did not try to set the MFI; called in a pro, Mr. Eisenbud, in Denver. I've driven it 425 miles, it needs more adjusting. I've been led to believe dialing in the MFI is a rare art form.

yellow circled bung is for MFI warm up, #2 is from engine cooling fan too shrouds and cabin. There are SSI's for MFI and carbs/CIS models, make sure you get the correct one.
the MFI gets two hoses and the rest just one if that helps.

On a 69 MFI car you do not use #2 and the port circled in yellow. In fact that whole rear shell that covers the 3 pipes exhaust can be cut off to achieve the stock look. It seems Dansk only makes one SSI to cover several years. Have your mechanic compare it to your existing one. He’ll know what to do.
