Dave are you run the walbo double pump all the time or just run one until you want more power do a switch to turn both pump on?

 

^ Dave runs his 2nd pump on a Hobb's switch.

 

Do you happen to have a list of the part numbers that you used?

 

I'll see if I can put one together and post it here.

 

Ok, Thanks.

 

any updates on this?

 

 

We need an update on how it is working out. Drop a line or 2 on us man . Thanks

 

 

I have kind of a similar setup. I drilled and tapped the rear of my tank for my second pump, except I ran my hose straight to the frame side instead of the driveshaft side. I'm still using a walbro intank as my main pump, then the second walbro kicks on at 6psi boost. I have my second pump/line going all the way to its own inlet on the fuel rail crossover, never had any issues running almost 1000hp on e85 and stock rails. And that tank is beefier than you'd think. I put a good amount of torque on the 1/2"npt fitting while installing it with no sign of pulling the threads out.
