external or internal fuel pump?

[ken yeang]

My internal pump just kong. I'll be getting a "new" unit from kreta potong. I see many modders use external fuel pump....and I'm thinking of using one. I need to know what is the advantage of using external fuel pump compared to the internal ones? Are external pumps designed for performance or they are just outdated pumps (compared to internal fuel pumps-in tank type)

As i would likely to get the fuel pump from kdeai kreta potong, how do I know the capability of the pump, like how many cc per minute...etc.

thanks

u can use external pump but if u use standard fuel tank...when cornering be prepared for fuel starvation...cause the fuel is sliding with the G force...most people use external pump with racing fuel tank...better use back ur standard internal pump then if not enough fuel then add external pump...internal pump can suck continues fuel in ur standard tank even when cornering...u can try if dont believe...

From what I heard, internal pump will last longer due to it's soak in the fuel thus giving cooler working condition but the problem is, need to take down the whole fuel tank when changing or service the pump. As for external pump, good thing is easy to change, service or upgrade. :regular_smile:

From my experience.. external fuel pump would be more like the original internal fuel pump into a surgetank and than from there two more high capcity pumps into your engine.. this will help with cornering lack of fuel...

I have an external fuel pump for sale......merc brand, made in germany.........

very good condition and much more quieter than the bosch pumps..............
price : RM how much u can offer................

From my experiance, external fuel pumps gives a lot of extra power compared to internal pumps, as the internal pumps are weaker than external pumps........
This is wat i feel lar, dont shoot me ok.....................

question - If internal pumps are good, why most of the sport cars, rally cars use external pumps? i was just thinking lar..............
