    Yesterday I was detailing the engine bay of my 1989 TR. On the passenger side rear corner I noticed two small canisters attached to two braided hoses. What are these canisters? I noticed them because they became unattached to their orginal base. Does anyone have a schematic showing how they are suppose to be attached?

    Thanks

    They are the charcoal canisters of the fuel anti-evaporation system. They are held in place by a formed metal strap (item 18) that goes around the rectangular canister mid-body, as shown in the jpeg, which attaches to another (less-deeply formed) strap on the chassis (go to www.eurospares.co.uk for access to these SPC drawings).

    You don't mention your TR version or location, but, if the body of the canisters is a different shape on your set, they may have been replaced (i.e., substituted) or added. If they are a different shape, what is the engine family number shown on the top of your engine block (F113A040, F113B, F113B046, F113A, etc.)?

    Thanks Steve - I will check the engine number at noon. The fuel connection makes sense because when I moved them around there was a faint smell of fuel.

    My engine numbers are 113A040 followed by 17565.

    Does this give you any insight into the type of canisters that I have on the car? & the attachement method?

    My canisters look very similar, although I dont recall the plumbing between the canisters as looking like the schematic. ( I will need to look closer at the plumbing)

    Thanks

    F113A040 is a US version TR so it should have originally been equipped with everything shown in that jpeg (the "17565" is your unique engine serial number).

    Have a closer look and see if your canisters are different or if it's just that you are missing items 18 -- i.e., check if they would fit into the remaining half of the bracketry on the chassis. I can't think of any reason that items 18 would be left off intentionally unless they didn't fit

    Steve - I looked at the canisters/hoses last night and they appear match the schematic. It appears that they attach to the back side of the passenger side wheel well? Do you know what type/size of fstener to use? Do I screw the fastener in from the tire side towards the back of the car or from the back toward the tire well?

    Marc -- The other side of the "clamp" holding the charcoal canisters is a 2-piece sheetmetal bracket that is riveted to the engine compartment side of the rear section of the RH rear wheel well. The bolts+nuts attach the 2-piece sheetmetal bracket to item 18 -- i.e., no bolt nor nut inside the wheel well on the tire side (just the rivet heads).

    My guess is that this mystery 2-piece sheetmetal bracket is considered part of the rear section of the RH rear wheel well (item 29 on TAV 102 in the TR SPC) so it doesn't have a separate PN. Unfortunately, the figure in the SPC only shows the wheel well side of item 29 (and I'm surprised that there aren't different PNs for item 29 for US and early euro versions).

    Does your VIN decode to a US TR (www.red-headed.com)?

    I will look at the VIN and advise.

    If I am understanding your descritpion I will need to use rivets to re-attach? The spot where it was previously attached is VERY vlean sheet metal. In fact it is a stark contrast to anything around it.
