Fri, 21 January 2005 06:26 First and major consideration: Will your return line from the fuel rail go back to the surge tank, or back to the main fuel tank? If it goes back to the surge tank, like the diagram you show above, then almost any low pressure electric fuel pump will do the job, as it never needs to flow as much as the main pump, because the surge tank is always being replenished by both the lift pump, AND the returned excess fuel from the rail. If you return to the main tank, then your lift pump will have to be able to flow the same amount as the main pump, otherwise you risk running the surge tank below full. In my experience, DO NOT use a holley pump unless you absolutely have to (ie: second option where you need a high flowing low pressure pump), as they are noisy as hell, even with good rubber damping. Fine if you have a thumping great pushrod V8 in the front rattling away though The pierburg low pressure pump is a compact, and quiet option, and can even be found at wreckers in cars such as early carby hondas (civic etc). Sorry for the long post! Cheers [edit] as turboRA28 mentioned, if you do decide to run an EFI pump as a lift pump (like VL), just make sure its mounted BELOW the level in the fuel tank, as they don't suck air well, and won't last if they are forced to.
