Depends on the 6.5
Since I have 2 Walbro's, and don't want to sell one due to the 1 in a million being me who had a failure, lets talk about plumbing them up.
In parallel, what would it do to fuel pressure?
What about in series?
Right now I have 5 - 6 before the IP, the flt mgr and racor are taking over 5. Filters are 8 months old and I suspect took a beating. Fuel pressure at water drain pegs out my 10psi handheld gauge fast. Anyhow....
Both pumps being after the racor, and before the primary filter, plumbed in parallel should split the racors resistance, and split the flt mgrs too?
What about in series?
The first walbro would take all the racors hit, but It would probably just make the 2nd walbro work easy until demand is called, then I can't see much benifit this way.
The other option is putting it in the engine bay, after the flt mgr, before the LP, but not sure if that is recommended for IP health? Can't see why it would hurt, unless the walbro came apart (there must be wear particles)... last chance screen on the IP??
Now that all my plumbing is fresh rubber, and I have the 2ndary walbro, this is free and fast... I would like 10psi going into my IP for some reason.
Turbine Doc, you have 2 pumps wired in parallel, walbro and heath HO I believe, what does your fuel pressure do at the IP different then when just running one or the other?
