i run external fuel pump and Surge tank as i am fed up with changing internal fuel pumps over and over again. new, old, performance and normal i tried all. busted after a month at most and 3 days the least. Until now dunno what happened.
changed to external and problem solved since. but because of the fuel splashing around the tank during cornering and in my case, accelerating from standing start, the fuel pump will not constantly feed to the injectors.
VERY VERY DANGEROUS TO HIGH BOOST APPLICATIONS! imagine you are dragging with someone lah...then 1st boost...2nd gear....3rd...bai...running lean bai..eh? no fuel bai...BOOM!...there goes your piston,conrod,valve,cam, block... :D :D :D :D
it is very useful for track day fanatics, and those who modify carby fuel tank for injection applications. daily drivers at urban areas need not apply, unless you want that shiny little shaft for shows..hehehe :D
a recommended item for track day freaks and nutters! :D
