Quick bike pump question
David Jenkins - 5/6/08 at 02:55 PM

Apparently the bike pump I bought off ebay has arrived at home.

I would like to start installing this tonight, so I need to ask a quick question - looking at the picture below, is the input pipe the one with the protection wire round it? The one that connects to the white cylinder, which I expect is the input filter?

cheers,

Probably!! Usually the filter will be before the pump to prevent crud going through the pump. If you connect it to a 12v battery you'll see it whizzing round. One tube will have a waft or air coming out of it the other will be gently sucking. Problem solved

the other way is to do what I did. Connect it up and switch on the ignition. If you hear the fuel tank bubbling (like I did!!) you've got it back to front

The filters normally have an arrow on them.

That sounds right to me! Mine has a pre-pump filter.

However as it's from ebay, I'd fill a mug or jam jar up with petrol, stick the hose in it, connect the pump up to a battery and just check it works before spending hours installing it.

No need to run it for ages, just enough to test it.

Is there not INLET cast in the plastic next to the pipe??

Nice to see you got the one I found for you if indeed thats the one

on my pump, no matter which way round the wire's were, it still went the same way.

and that is right the filter goes before the pump(so it is the input)

Yep - that's the one! Looks in good nick... I'll give it a whizz later to check it's OK.

It was from a bike breaker in Colchester, and it arrived very well packed and clean. If it runs OK as well then they deserve some good feedback.

UPDATE: Oh look - it has 'inlet' written next to one of the ports!
And it seems to have plenty of puff on the outlet.

Am I right in thinking that it can be fitted in almost any way up?

I don't know how it went in the bike, but I plan to fit it horizontally.

Rats!

I've just noticed that the outlet is 10mm diameter - and all my pipework is 8mm!

Looks like I'm going to have to make an adaptor...
...just like the one on the inlet side, where the inlet pipe and filter are also 8mm.

Shame, as I was hoping to have it fitted for the weekend - unless I can get it sorted on Saturday.

mine is fitted upright, and when it was in the bike it laying down. and mine works so i would have throught it would.
