but im looking at the specs of them and they only go up to like 7 psi ? am i being silly ?
looking threw a Cresent suzuki bike GSXR manaul (my z car has a gixxer engine) it states the fuel pressure should be 43psi !
i cant find a pump that will reach this ? is this correct?

new pump from suzuki is £300, but you can get them from ebay for £50 ish, althought is has to be mounted under the tank (drilling a holes that could leak)

hi there i used a fuel pump from a hyabusa from a bike breakers no need or a regulator just bolt on and connect hoses as the pressure is the same
The hayabusa pump has an adjustable fuel pressuer regulator built in but it is activated via a vacum pulse from the inlet manifold to adjust the pressure as the revs increase so just running it as a pump will not give you a correct pressure???
Hence the need for an adjustable pressure reg.
One disadantage i noticed with the hayabusa pump and fuel system is that it doesnt have a fuel return so when it has been running for a while then left to idle it suffers from fuel vapourisation as the fuel is warmed by the coolant pipes in the tunnel and because it isnt getting used quickly it just vapourises and cuts out until it cools down, if it was a circulating system this wouldnt ocurr so i am modifying my current setup foa recirc system.
