As the title saids I'm debating on what pump(s) I should get.. Thinking of taken the line from my pump to my Y block and upgrading it to a -10 (my whole system is a -6 now) and running 2 walbros GSL 392'S so basically it be -10 from the tank to the y block in the engine bay. Then -6 would come off the Y block and feed each rail, after the rails come to fuel pressure reg and return be a -6.

Will this be a problem?

what pumps are you guys running?

My old car had two Bosches on it. I had a sump in the tank and fed each pump with its own -10(or maybe it was -8) lines. Then I screwed in Kinsler filters into the pump outlets and ran -8 lines out of each pump and into their own fuel rail. I then ran I think -8 or maybe -6 lines out of each rail and into a Weldon regulator which then had a -6 return line back into the top of my tank. The exact same setup, except filter selection, was on my friends car and supported around 1200 fwhp. He later rigged in a third Bosch and was supporting closer to 1500 fwhp.

Those pumps look to be exactly like the pumps Mercedes used on the two 1985 cars I have owned(500 SEL and 380SE). Back when I had an SC combo I used to use stock lines with a 190 intank pump and a Bosch inline and used the stock filter setup as well as rails. That setup supported around 550 fwhp without any issues at all.

Personally I'd never use anything but a Bosch pump. They are not too loud, they do not have over heating issues and the list goes on but at the end of the day they support a good bit of power per pump as well.

Snipe is right on!

Don't think you need some "big name" pump to support hp. These OEM style pumps are proven and WILL last under DD conditions.

I agree with above poster. I have been running an Eliminator on the street with no controller and have had no issues so far with a sumped tank.
My other car has a Glenn's Performance fuel system and that is a nice way to go also. Each 255 pump feeds 1 rail.

For those of you running the walbro GSL 392 with the Glenns system, which wire goes to what terminal. The pumps I was sent are not marked. Second question what size wire did you use to connect power to the pumps
