Stupid Queston

I hate to ask, since I didn't do something as simple as take a picture or make a note.

2000 528iT (M52TU): I removed the fuel lines to remove the intake manifold, and didn't label which was feed and which was return. It seems to me that any engineer worth his salt wouldn't cross fuel lines if he/she didn't have to. So, as long as the fuel lines are running paralell from the firewall to the fuel rail, I should be okay...

Right?

If it was anything less flammable than fuel, I wouldn't ask such a needy question. But I figure where gas is concerned, better to risk looking stupid for asking a question than to prove stupidity by torching my own car.

Thanks again!

I never gave it a thought - just reconnect the lines as they line up. I never tried it, but I don't think the fittings can be cross-connected.

Near as I can tell, the fittings (on mine, at least) are identical.

I figure (foolish hope?) that if I've gotten it wrong, the leak detector will trigger codes, thus halting the fuel pump.

Hey, 45 views and only one answer! Maybe it wasn't such a dumb question after all.
