I just need to attach the 2nd pump to the top hat. Kept the fittings to hold the return lines. Looks decent.
Only cost me about $450.
You should have looked at the post I made almost a year ago with a DIY dual walbros. For the same amount of money you could have had a better setup, imho.
I didn't want to use Hydramats. And if I did use them I would go bucketless.
Bucket - 50
2x Walbro - 215
2x Hydramats - 320
PTFE Hose + Clamps ~ 20
Total = 605
My setup is $150 less, and I have the peace of mind knowing I wont have starvation issues. And I know the bucketless option flows more due to losing on the venturis, but I heard something is coming out soon to help with that.
https://bmw.spoolstreet.com/threads/dual-450-walbros-ultimate-setup.1761/Tec. Can’t you post a link? I’d love to see both. I’m pretty sure I’ve read it though on bummer boost I believe?
Lol! My setup is bucketless. There's no bottom on the fuel pump assembly.
One thing is for sure I will never have starvation issues with my setup. The hydramats will suck the tank almost bone dry and with the way I have it installed, the mats touch the lowest parts of the tank. I've run my tank down to zero, will all the warning lights shouting at me and the car never hiccuped. When I did finally fill up, I put back in right at 15.9 gallons.
The great thing about the way mine is setup is that the return line is placed above the mats so they can't help but stay wet.
Anyway, if you like your setup.. great! Good luck with it.
I'm a little lost on the venturi thing, so it looks like some use it, some don't, some only use it on one pump? Can someone please explain the pros and cons and where each can be used?
