360 Differences between fuel vapor (charcoal) canisters-'99 360-modification possible?

I have been having the gas pump switching off issue since I got the car so I finally decided I was going to swap out the canister. I did my research and since I have an early assy. # (33xxx), all research pointed to 174782 being the correct part. I even verified this with the part that was currently on my car....but after ordering, it looks like for some reason I have the later part, 180132.

The difference is easy to see...the 174782 (the top main picture) has the "vent" side of the canister closed off, while the bottom picture (180132) has a nozzle on that side, leading to the on/off valve (45 on the bottom pic). Both are the same Dayco B460 canister and have the part marking "174782", apparently after the design change, they just used a sticker to show the new part number, which apparently fell off of mine.

My question is this...I have not removed my old canister yet to test any theories, not have I received the one I ordered...but could I either

1. Modify my new canister to accept the nozzle from the old one and keep the setup the same?

OR

2. Delete the on/off valve altogether and just use the new canister as designed? Will disconnecting this create a CEL? The valve only has a hose connection to the canister, but does have an electrical connection.

A third possibility after looking at a few pictures...maybe just getting rid of the quick-disconnect altogether for the vent tube to the valve and just using a vacuum hose/clamp setup.

 

Well, apparently the parts descriptions were just not very good, and this canister was used for Euro models of the 360...but I received my new charcoal canister today from @carguy246 , thanks! . The plug over the vent hole is just a cap that pops off, and the only difference between that and the 180132 is an extra "nipple" that is glued onto the existing port to accept the hose to the on/off valve....sooo with a bit of poking and prodding I discovered that with a little redneck creativity, some cheap beer, a little heat, a utility knife, and a LOT of patience, that nipple can be separated from the original canister and then fit to the 174182 port after the cap was removed. I will be using some heavy duty plastic epoxy and my $100 investment is going to pay off....

Hahaha! I’ll be sure to do that..

 

I think the rollover valves can cause the same condition also, have you checked those?

 

A little high strength plastic epoxy and a spot of spray paint you’d never know it wasn’t factory....right?

Wasn't asking anything, just showing how I got a great deal on the "wrong" canister, new, and hillybillied it to become the "right" model.

I still plan on getting the full monty....at some point, as we discussed, but not sure if I will go as far as removing the complete systems that had been bypassed, other than the immobilizer. My main concerns at this point are sending my ECU's overseas, and having a backup of the programs if I do in fact remove my immobilizer system..

 

Awesome, do you provide backups of the modified program in case of an ECU failure? My concern is that if those systems are removed from the car, and an ECU failure forces a revert back to the original program, then it will go back to looking for those systems and render the car un driveable
