HKS Vacuum hose? Seriously? How much is that costing you?!?! Totally pointless IMHO.
Just get boggo hose dude, honestly - Samco will do you fine. eBay special did me fine too.

For the rat\'s nest you need about 5m of 4mm and about 2m of 6mm IIRC.

its £20 for 2M, i just wanted some good quality hoses. i bought some ebay special and i think its causing me problems. if i changed the 4mm vacuum hoses to 6mm will it cause me any problems?

if you want good hose... look for hose solutions they are from america but do a full kit of all the pipe sizes you need for the fd rats nest... comes with some cutting tools as well... was a review on rx7 club or something and they said its the best hose to use.

£10/m?! Fcuk a pig...

You just need Viton hose - why do you say it\'s causing you problems?
I wouldn\'t change the dimateter for tyhe simple reason that it won\'t fit the existing connections. TBH I think it\'s more likely that your issues will be due to either a misrouted hose, or a duff solenoid/check valve.

http://www.coleparmer.co.uk/ is a great place to buy hose and one way valves. they give you all the spec like max and min temperatures of everything.
 
their Viton hose is a bit pricey though, £50 for 25 feet (about 8 metres)!

I\'ve brought some do luck silicone hoses from sumo power, they had 4mm and 6mm vacuum hoses on sale, I got 6m of 4mm for £22 delivered and 3m of 6mm for £11 delivered. That should be enough to sort out all my pipes
