hi, is the Vapour separatoi need, as i will be runing bike carbs, and will i need to run a return pertol pipe, and what size petrol pipe do i need???

Thanks

Stuart

you don't need the vapour separator, nor do you need a return line.

what you will need is a carbed bike fuel pump that self regulates the pressure and shuts itself off when it reaches pressure.

so if i keep the Vapour separatoi can i use the standed fuel pump with a return line?

Stuart

Sorry for the hijack. I am just putting in my copper fuel line to go from front to back through the tunnel. I have a pinto with bike carbs so I understand that I only need one pipe however I am thinking of running a spare pipe to prepare for a future upgrade. Under what situations will I need a return pipe. I.e what engine, fuelling etc.

Many thanks Andy

you can probably get a bike fuel pump for a tenner to £15. then you just need one fuel line and a power wire.

it'd make a lot tidier install and is the tried and tested method. i don't think the vapour seperator is a pressure regulator, so you'd probably need one of those too. i'd do anything to save running a return line as then you get into extra tank connections and all sorts of other complications.

thanks tom for the help will have a look for a fuel pump, does it have to come from a 600 as i got cbr600 carbs??

and of the topic, but does a 1.6 pinto go well in a indy?

Thank you

Stuart

Any bike pump will be ok. Make sure its a carb'd bike pump not a fuel injected bike pump. The FI ones run at much higher pressure.

Or just use the pinto pump with a pressure regulator.

so what size pipe do i run?

Thank you

Stuart

i've used 8mm copper microbore from tank to engine bay.

it depends what the unions are on your pump as to what you need to do from there. i used a thundercat pump for my blade carbs, which has 10mm connections. therefore it needed a 10-8mm reducer on the end of the microbore to increase the size for the hose to clamp to. then i just ran it on 10mm i/d rubber from copper to pump, pump to carbs. the pump's infront of the nearside engine mount btw.

a 1600 pinto's more than adequate to make a 7 go. it's not nearly as rapid as a BEC or even a 2.0 pinto, but it'll still put a smile on your face. i started with a 1600 because i was 19 when i first insured it. now i'm thinking of going 2.0, but i think i'll run it for another summer on the 1600.

thanks tom, i was wondering the pump goes, as i got a cbr600 pump for my bike carbs.

As well i am going for a 1600 pinto as it will be my first car.
