    Hi chaps,

    I'm having a bit of a mare at the moment trying to find a sutible washer bottle for the Gooster - so much so I think I'm going to have to build something myself to fit the available space.

    What I need to know is what plastics would be suitable for use in the engine bay? It gets hot in there, so something with a high melting point would be good - but there's also vibration, possible chemical attack from fuel, oil etc.

    What I really need is something that will fit the following max dimensions - 80mm High, 150mm Wide and upto 300mm long. Height would have to include any filler neck / fill port. It would also need an outlet barb that would allow the washer jet pump tubing to fit on to (I guess I'd have to tap the material and add a sutible metal barb in)

    Any ideas on Materials? Or is there anything out there in water cooling land that might suit? (I've already had a look at bay resevoirs, but most of them have windows etc that really aren't neccessary, and they probably arent up to the rigours of automotive use.)

    Thanks in advance

    GOO

    I'd make one out of ~8mm acrylic (should be anough to take the bumps and scrapes) and have an aluminium outer coating for a heat deflector, which would also work as a shield for any chemical attacks :)

    could you not use fiberglass and a lost foam casting method ( make the foam mold to fit where you want, cover with fiberglass then melt out the foam).

    Oooo. Now that's interesting... :)

    As I've been googling at lunchtime, I have been toying with the idea of getting a Aluminium water bottle (you know, like hikers & campers use) and bolting a generic washer pump to the bottom, and then attach it to the top of the scuttle (the only place free of air intakes, pumps or hot exhaust manifolds) on it's side.

    Even if the lid is on the top, it's water proof, so shouldn't leak - and if I'm clever with the mounting (something similar to a bike bottle holder, or a cradle with some velcro straps), all I need to do to fill it is remove it from the holder, tip it upright, open it up and refill and then close it and put it back.

    I've just got to find a bottle that doesn't have too big a diameter.

    The problem with a bottle like that would be that it needs to be vented otherwise the pump wont be able to suck the fluid out of it.

    I would be cautious about acrylic, acrylic is known to react with the ethylene glycol in antifreeze and crack and some windscreen washer fluids also contain ethylene glycol. I'm not sure about fibreglass or rather the resins used though you could probably seal the inside with something that wouldn't react.

    Yeah - I'm going to vent the bottle by drilling a small hole on the shoulder - that way it will face upright when the bottle is laid down. A 1 - 2 mm hole should do - it's what most plastic washer bottles have
