Petrol Tank Fitment

I am replacing the fuel tank in my 1500 and wondered what everyone was using for the foam type pad that fits underneath it
suspect to stop vibration etc..
The parts catalogue calls for P/N 617885 but struggling to find what the make up of the part is.
Easy enough to get some foam strips, but knowing these hold water in a delicate area, wondered what other options there may be.
Thanks in advance
Nigel

Hi
I just used rubber sheet, I googled "fuel resistant rubber sheet" and ordered some from eBay, its 3mm Nitrile, 4 years later and no issues.
Regards
Barry

Even the factory foam fitted under the tank wasn't water resistant and has been responsible for many a rotted tank as water ingress into the boot seems endemic on Dolomites!
My personal preference is leave it out entirely (and the bung grommet) then it CAN'T cause trouble later! I've never suffered any ill effects from this method, such as booming or vibration, so it seems like a no brainer to me.

Thanks both for the feedback...
I am tempted as Steve suggested to leave it out all together.. I also have taken the bung out on both my cars to aide draining
Cheers

I left mine out too.
However, I have been pondering this. If you want an extra surrort or whatever, how about putting a bit of greaseprrof paper on the boot, central to the tank. Get a tube of silicon sealant/tigerseal etc and put a big hefty swirl on the greaseprrof paper. Then pop the empty tank in position, maybe with washers to act as spacers to lift it a smidge over normal position. Let the sealant cure, lift tank out and remove washers. Should be a very nice fit, giving support and no issues with holding water.
Probably overkill though. Other ideas included using some rubber hose chucked in teh gap, but you would need to measure the gap first. Blutack/paper for that.

I would be tempted not to use Silicon sealant unless it is RTV, because silicon sealers use acetic acid as a curing agent, and will rot out in double quick time, I have seen cars that used bathroom silicon as seam sealer, where you can pull the silicon away with the seam of rust almost like a zip to remove the repair

Whilst on the topic of tanks, are Toledo tanks the same as Dolomite? I may just have a leak.....

Sorry, but no, the Toledo and Dolomite tanks are NOT interchangeable, the Toledo tank is shorter, front to rear and has a smaller capacity (8+ gallons to the Dolomite's 10+)
To complete your misery, the Toledo tank is made of pure unobtanium, I've seen a sound one advertised for £300, though I don't know if it sold. I have got one here in excellent condition, a 1999 built replacement (I have the bill and warranty still) But not sure yet whether i'll use it in the Carledo's next incarnation, or go for a fuel cell.
