Early e's have it in the engine bay next to the charcoal canister. Was just looking at my friends 84' maybe it's an es either way, there's a bracket lol

Interesting, I stand corrected. I've had an 9/86, and an 87. Both had the fuel filter in the rear. Maybe they made the switch late in 86.

My 2/86 production "es" had it mounted in the engine bay.

I relocated next to the pump for the shaved-bay S50 swap. I wish I had seen the simpler mod before I did this:

The fuel filter is mounted in the rear on e cars also.

Also you could procure a fuel filter bracket from an e I think? Where the filter was mounted in the engine bay to secure the filter like factory.

Thanks. Works well. Hose clamps holding things aren't so classy but no one sees it.

For those of you looking for a clean simple install.

Here's what I did,

Remove external pump bracket, remove fuel filter from bracket, mount fuel accumulator to spot where filter was, move filter to engine bay near charcoal canister.

This is my favorite solution so far.

Just posting to remember to come back to this once I take pics of my solution, which was a full surge tank setup.

BUMP. Got the last one from GPS today. Found this link. Might be helpful for future reference!

updated site, added more inventory, we have a few left.

^ That looks like a good idea. I need to get mine installed. Tired of trips to the gas station after every other session.

It's a 91 318is. So just the single pump in the tank.

Here's how ive got it routed:

Low pressure in tank -> surge tank -> fuel filter -> external high pressure -> fuel rail -> return to surge tank -> return to Tank.

You want the external pump after the surge tank so that in moments of starvation in the factory tank, you will have the secondary pump pulling from the surge tank. Also, route the fuel filter after the surge tank so that any unused fuel the returns will always be filtered a second time.

That is awesome. So far everyone has talked about switching gas tanks and I was dreading that. I have the piece and will likely install it sooner having seen your setup :)
