    Evening gents.

    I need to know if 3, 5 and 8mm silicone are the correct sizes for replacing all the rubber hoses in the engine for the expansion tank, charcoal canister, boost lines etc?

    I know the boost lines, like dv are 3mm but what about the rest.

    Dan :).

    I got 3,5 and 8mm and replaced it all,so yep!

    Ohh, and some 25mm from charge pipe to DV if you wanted to do that too :)

    8 mm will do a lot of it. I bit the bullet and got the forge replacements and got the silicone lenghts at the same time. Just to note I ordered a length of 13mm hose to replace the pipe under the DV but it arrived as a 13mm outer dia not inner, so be carefull if your ordering any other bits.

    I've had all the hoses available for Forge replaced on my S3.

    How much of 3, 5, 8mm should I get to do the rest?

    Is it just straight hoses I need, or any elbows?

    Roughly how many jubilee clips? What sizes?

    So, the shopping list would look something like:

    * 3mm Vac Hose (1 metre) 3mm Silicone Vac Hose Boost Dump Valve BLACK 1M on eBay (end time 20-Feb-11 12:02:31 GMT)

    * 5mm Vac Hose (1 metre) 5mm Silicone Vacuum Hose Pipe Silicon BLACK 1 Metre on eBay (end time 20-Feb-11 12:22:54 GMT)

    * 8mm Vac Hose (1 metre) 8mm ID VACUUM TUBING SILICONE HOSE SILICON RED 1 METRE on eBay (end time 27-Feb-11 11:09:11 GMT)

    * 8mm Straight Silicone (1 metre) (5/16") 8mm ID BLUE STRAIGHT SILICONE HOSE 1 METRE on eBay (end time 17-Feb-11 17:23:21 GMT)

    * Two lines to fuel rails (8mm fuel resistant) 8mm 5/16" Silicone Fuel & Oil Hose Flouro 1 Metre Blue on eBay (end time 25-Feb-11 16:17:56 GMT)

    * Pipe under the DV (1m of 13mm straight silicone) 13mm 1/2" Silicone 1 Metre Straight Hose Silicon Black on eBay (end time 04-Mar-11 10:33:47 GMT)

    Nar, that 19mm if i remember correctly, tbh though, normal silicones fine for that, it's not like its got constant oil running through it.

    Its the coolant bottle by the charcoal canister

    By the way I made a mistake, it WAS the pipe between the hockey puck and TIP that was the 13mm I/D pipe not the DV..my bad
