I have a 2000 Deville with dual AIR pumps and I am trying to figure out the part numbers for both pumps/hose kits. Can you help me out? Thanks in advance.

both are the same part number

$249.26 (list price each)
$155.79 (forum discount price each)

i do have two in stock currently

and this is the kit that comes w/ the hose

let me know if you've got any questions

So it looks like the exhause hose for the passenger side AIR pump was routed improperly as well, since the drive belt has chewed a hole into it. Do you have a part number and price for that? Thanks.

is this the part you're talking about? #627 ??

(i think that's the passenger side)

No, it runs from the outlet of the (second) secondary AIR pump, across the carriage, somewhere into the rear of the engine bay. I'm guessing to the exhaust manifold...

ok, i think we have a confusion of terms...

the rubber hoses from the pumps goes to the valves (#630 in the picture) the valves then routes the air to the exhaust manifolds thru a metal pipe (#627 on this side)
you can see the dashed 'locating line' going through the nut (#626) to the rear exhaust manifold in this case
the illustration here is only showing the passenger side (i zoomed in and cropped it so it would be easier to see)

the rubber hoses coming from the pumps are discontinued although i might be able to send you in the direction of a dealer that still has one to purchase

yes, it's the rubber hose coming directly out of the AIR pump outlet. Can I see the full image?

the catalog says that both these illustrations fit your car, but i think the second one is for cars that have only one pump

Yea, that's the driver's side. Passenger side is completely different.

08-10-11, 05:38 PM
passenger side would be the bottom half of the first illustration

#14 is the hose
#17 is the valve
(pump not pictured because it's the same as the driver's side - #5)

Looking at this illustration, see the hose that appears to go under the engine? This is what I need.

Now, comparing this to your illustration, it looks like it may be #14. It's just that your illustration cuts it off...

Correct, same part different pictures... mine is from the parts catalog, yours (i would bet) is from the service manual

so that hose has been discontinued ... but there are dealers that still have some on the shelf

i could point you in their direction (email you a list of dealers who still have it)
or i could try and get one for you from them (as a middle man)
