i dont know if anyone has mounted two walbro turbine pumps in the tank but if not would be fun to try! they should get you pretty close.

other than that you may be looking at a more noisy external using a sump fitting out the bottom, and there is always mechanical

-10 feed and 8 return depending on how the pump ends up probably fine.

I have Dual walbro 450 e85 pumps in my Turbo T/A, using a -10 90* bulkhead adapter where the factory hardline came out of the tank, using a Y fitting to tee both pumps into the -10 adapter, which then runs a single run of -10 into another Y by the rear of the fuel rails, which splits to -8 going to each rail, then out the rails into my aeromotive a1000 regulator, which returns back to the tank using the original factory fuel feed 3/8 line.

The OP has a 98 car which is a different fuel system set up than what you posted.

The fuel system on my 97 is similar to the 98 so this might give you some ideas.

This is with twin Walbro 255s which I eventually upgraded to Aeromotive 340s. My uncle machined the mounting bracket which the pumps sit on with one sitting just slightly lower than the other so the socks don't interfere with each other. Everything fits into the tank with the stock fuel level sender though it is a trick to get them in without knocking the socks off the pumps. You definitely don't do it with any fuel in the tank.

That looks really nice. Did you use one of the 4 hardlines coming out of the top of the tank?

I have twin 450s in my stock 94 tank. It took a little push to get them through the hole, but they're in there now! Wiring has been cleaned up since these pics, but this is all I took before they went back in the tank.


Used to run one 450 and one 255 so that is why one of the socks is already yellow.

I used all 4.

The two on the right are 3/8 feeds to #6 lines which merge into a Y block to a -8. The Y block is big enough to run up to -10 if need be. The one on the far left is a -6 return. The uncapped one in the picture is the vent. The return actually dumps fuel back onto the pumps to attempt to keep them cool. No issues so far.





And the intake/rails.



When I get around to rearranging the system for the LSx transplant I'll take new pictures.

Racetronix makes a dual 340 pump setup with a bracket connecting them together and a billet y block
I hose clamped around the bracket to the original sender, took a few tries to get them to sit on the bottom of the tank but it's working fine
