am gonna crazy about fuel pump selection,internal or external????and why i think with why it would be a great answer http://fsae.com/groupee_common/emoticons/icon_smile.gifneed ur help guys

You might get an answer if your question is in a way that somebody can understand it. Anyway: Use the forum search function. What amount of pressure do you want, what flow rate do you want, etc...
Nobody here will give you exact data when you are just randomly asking questions.

Use this: Delphi Series 7000 Fuel Module (http://delphi.com/manufacturers/auto/powertrain/fuelhandling/series7000/). You can get them in most recent passenger cars (or at least that's what's common in AUS), which means they're a pretty common spare part, if you don't want to use wreckers. Internal, returnless fuel system.

That's my answer to a question you didn't ask. Now its your job to figure out what the question should be.

Ooh, that one does look pretty hot. Simple and compact, looks pretty easy to package. We've tried fabricating similar units in the past, but they just haven't turned out right yet. It's nice to have an already developed injection molded unit.

Plus it also has a fuel level sender, so if you really wanted you could add a gas gauge http://fsae.com/groupee_common/emoticons/icon_biggrin.gif

my question,there is two locations for fuel pump,1-in-tank 2-or external,some says that internal pump is complicated but it don't need for cooling system as it is in fuel tank which provide cooling,so i wanna know the advantage and disadvn,for two locations, and if it depend on pressure or not

[Rex Chan]

Osama: I don;t think many teams cool their fuel. Actually, now that think about it, the rules PROHIBIT you from changing the temp (and hence desnity) of your fuel.

The internal pump is simpler, as the whole thing is one device. If you do external fuel system, you have to pick/buy/package a bunch of hoses, fittings, pumps, regualtors, etc. The downside of an internal system is the constraint of having a certain height fuel tank with flat top/bottoms.

There seem to be a few posts on here about starvation when the level gets low for external systems (i.e. slosh the fuel too far, uncover the pickup, engine hiccups). The solution is much more complex vs the internal system, which apparebtly has it built in (if you beleive Delphi's website).

All fuel systems are designed to handle the pressures we'll be dealing with (we run 3.5bar).

I think he could referring to the cooling of the fuel pump itself. Some pumps require a certain flow of fuel to keep from over heating. If you run a system with no return, the flow could be to low to cool the pump. This is less of an issue with an in tank pump as the fuel/tank provide adequate cooling.

[Rex Chan]

Oh, ok. Gotcha.

A returnless system does have a return - its just in the tank, and not outside. The pump gets +12VDC all the time, so flows the same as if it were outside. However, the pressure reg is on the inside of the tank, so the return flows a shorter path back into the tank.

thx for this data,i have another question about fuel filter is is inline filter or pre-tank,i think it is inline one,and i wanna ask about if there is oil kits for honda cbr600rr (2007 +)

That's actually somewhat incorrect. Ford uses a PID loop with a varying voltage to control pump flow to meet the needs of the engine at any given time. I believe some other companies are incorporating a similar system.
