Fuel gauge works fine,on both fuel pump holders there is a connection wich meassures the fuel level.
I will try to make a picture of it.
Where did you get that set up? Very cool. This is a nice alternative to a surge tank too.

I pulled the syphon side out today to see what was there. There is no surge bowl area for a pump. But the biggest issue is I was showing just under 1/2 a tank on the gauge and that's exactly where the fuel was as well. All on the fuel pump side. There was no fuel at all on the syphon side. So I wouldn't like to put a pump on that side because it would run dry and have no surge area. So back to what I was looking at I'm going to run 2 pumps on the one hanger.

Now the joy of trying to make it all fit.

You want lift pumps up to a surge tank and then inlines from the surge to the fuel rail. I've got the OEM intank pump, then two Carter lift pumps, twin surge tanks and then four 044 inlines going forward.

That might be what I need but it's what I don't want. Don't want to take up boot space with fuel system. It's a street car.

I doubt that will work out as good as running a Y connector outside the tank, mainly because the pumps will have to work against eachother , also a one-way valve should be fitted to the output of each pump..

It will outflow one pump though thats for sure

On a side note :
Is the Fuel level sensor thesame on both sides ?
If so you could just drop in another pump assembly on the driver side.

And whoever linked that 400LPH pump , it's rated at 40psi , i bet it drops really fast above that...

I agree it's not a perfect situation but it will work. The pumps won't work against each other that much, liquid still will always take the path of least resistance. Walbro's do have a check valve on the output barb on the pump. I would of prefered to do a Y outside the tank but then I would of had to do a bulkhead fitting on the hanger top. And there isn't much room to do that. Then there isn't much room to do much above the tank either.

To be honest this is the best comprimise in a bad situation I believe. And if this doesn't work well enough then the only other thing to do will be use boot space and do a surge tank.

How did this setup work out for you? I'm planning on doing a 2jz/e85 and need to figure out a pump setup.

how is the siphon system going to pull fuel from across the saddle connected to that chopped up fuel basket?

The siphon hose goes into the surge area on the pump side. Nothing to do with the basket

Here is how e36 guys run twin pumps. LINK

Using a modified fuel pump hanger with a fuel pump installed, to go into the non fuel pump/venturi effect pump side, I.e. A pump each side.

Also here apparently e46 compatible, there are cheaper kit's but I am unsure if they are designed like this one, no pictures on their websites.

This is Bimmerworld version:

no pix however...

I did find this pix of an OEM set up showing the fuel float sender located in the second fuel tank port:

http://forums.bimmerforums.com/forum...d.php?t=752438

The dual pump set up solves fuel starvation. You COULD rig up a sender based on a whole custom set up. They make all kind of ways to to read fluid levels. You may have a remote gas gauge, but it would be better than nothing.
