Can anyone post pics of rear mounted (trunk) electric fuel pumps? Also depending on where you put them, why. I don't want to mount to shock tower for potential rust entry...mounting to rear seat back seems to be too noisy...just looking for suggestions before I start drilling holes etc... was going to put a rubber pad under the pump to kill noise.

I've read that BMW recommends mounting under the top of the tank (helps siphoning or something), which is to say under the car. There's a space between the tank and the outside of the car, which I believe is where they say it should go... I know someone posted something about it here (with pics, as I recall), so you might want to search around a bit.

This is the set pre-megasquirt. The carter pump was noisy. The slip on leads seemed to slip off a lot, so I ended up taping them on. I put it there simply because it was convenient. Loose stuff in the trunk could be a problem. The black thing next to it is a crash sensor. It is recommended to run one with electric pumps. Underneath looks like it works too, unless some road kill gets it.

I put mine underneath the car, behind the wheel well on the passenger side. Pics here: http://www.bmw2002faq.com/component/option,com_forum/Itemid,57/page,viewtopic/p,731244/#731244

The Carter pump was way too noisy, and I highly prefer this one that I got from IE. You can barely tell that it's running at all, and it freed up some trunk space. You can read more about this style of fuel pump here: http://www.racetep.com/webfuelspark.html#webfuel
