Anyway, thank you for the feed back, i will get these capped off at weekend.

But my next query is petrol tank related.
I was reading in Complete Kit Car magazine and there is an excellent piece on setting up the fuel system, which made me realise i need a fuel pump! but it then read on about setting the fuel pressure provided to the engine, what pressure have you guys got yours set to??
Lastly the breather valve- is it ok to just have a small bit of pipe coming from the outlet, to a breather valve, then a bit more pipe just running up the back panel- maybe with an air filter on the end to ensure only clean air is sucked in??

Most of us are using tanks (beautifully made by k4kev) and are using the in tank pump from the mx5.if fits in with the loom etc.

A few people are using the mx5 breather. I am going to use one of the breathers available from car builder solutions. This will run up to near the filler with a bit of tube.

I agree with skov about the pipes. You can get nice silicone 8mm end caps on ebay fairly cheaply.
