fuel pump for bike carbs?
So im progressing slowly....ive bought a 1660 xflow engine from a member of the forum, ordered bike carb conversion from Danst engineering im not just
buying all the little bits.
Im now looking at fuel pumps.....i want to run a facet pump but need to know what kind of flow rate i will need. I was thinking this one....what do
you guys think.
http://www.jjcraceandrally.com/race/fuel-pumps/facet-interrupter-electronic-fuel-pump
The silver top road pump gives 4-4.5 psi and upto 150bhp...is that enough or do i go for the next one in the scale which gives 5-6psi and upto 200bhp?
I will be using a fuel pressure regulator aswell just to make that clear.
Any help would be much appreciated.

Id rather a brand new pump to be honest and facet pumps are very reliable and reasonably priced.

As others have said - use a bike pump (for carbs) They run low pressure (1.5 to 3 psi approx).
Low pressure fuel regulators are tools of the Devil!
Anytime I find a carb run car not fuelling correctly it is invariably due to a rubbish regulator.

Hi
I would agree with the others the ideal is the pump and the carbs from the original bike. Sure my old bike carb fuelling pressure was 2.5-3.0 Psi and
that was to fuel/feed a 2.0l silvertop.
An inline gauge is handy as well.

Bike pumps are cheap and very reliable and will work best with bike carbs.

i bought one of the solid state facet style cube pumps. think its upto 3.5 psi.
I haven't ran the engine in anger yet but seemed to be doing the job at ticker over.
Bike pumps are quite expensive even from breakers for 2nd hand one.

That's right - all it needs is 12v and a fuel supply.

Well thats certainly good news as a good regulator is £150+
Would i still be best fitting wiring it to the oil pressure switch as ive seen mentioned on here?

I have been running zx9 carbs on my crossflow for 3 years now with the zx9 pump with no problems.
Regards Denis. 
Where did that go?

Would it be a problem fitting the pump in the engine bay?

If you want brand spanking new and you want to mount it in the engine bay and you don't want a regulator Then the Huco pump sold by webcon for
dcoe carbs is just the job.
New, 120L/H and only 1.5psi

I use a Facet pump running through a Filter King with a pressure guage to get it just right.

If fitting a bike pump put it at the back under the tank. It will work better.

Im thinking bike pump is the best plan then guys!!! What makes them work better in the back of the car? I would prefer it in the engine bay tbh.
And are people wiring them to the oil pressure switch?

Agreed on stock pump. Low power consumption and very simple device (so reliable).
The reason people fit them below the tank is because they are not designed to suck fuel into them.
Folk do mount them in the engine bay and seem to get away with it, but there isn't any real disadvantage of mounting at the back.
Not sure whether wiring to oil pressure is worth the bother. The reservoir of fuel in the carbs means that the engine will run on a bit even when the
fuel pump stops. Maybe just fit a brighter oil pressure light if you are worried about possible failures in that area.

As said bike pump all the way, apparently they push fuel better, having said that mines been in the bay for 15k and not a problem on either the
original pinto or zetec, they did use the same carbs, btw any pump off a carbed 600cc bike or greater should be fine. Just watch out for the ones that
are inbuilt into the tank.

I run a 2 litre Black Top on R1 carbs with a Danst manifold in my single seater. I use a small solid state pump through a regulator and it never runs
short of fuel....
