Will this work?

I have 2 machines on my trailer with a seperate line to each one from the tank. That's how I've always been taught.
If anything you would choke down the 4 gpm when running both since the 8 pulls more.
What you have might work but don't know for sure.
 
Ed, a 2" fitting would be enough to feed both machines. But, with a common tank tap, if one pump goes bad, especially inlet seals or cracked pistons, the other pump can pull air through the bad pump instead of water. It's best for each machine to have a separate tap.
 
Ed the drilling is very simple it takes about 5 minutes and tractor supply sells the fittings once you snug them up there as good as the original.Dont take chances with the pumps its a simple fix that will save you $$ in the long run.Those lines you have look small to me if you want to be safe run 1 1/2 inch all the way to the machines.
 
I have a 2" bulkhead fitting on the tank.

Out of the bulkhead is a 2" "T" and on each side of that "T" is a line going to a machine.

On the side of the "T" that I don't use mostly or that much is another "T" that has a couple of smaller "T" 's on it. That is for water to fill buckets and 2 other pressure washers.

I can run 3 different machines, a 5gpm, 5.5gpm and 8gpm all out of the 2" bulkhead fitting and 2" "T" with smaller "T" 's after the large "T".

I would not have all of them off of the same side so I split them up so it evens them out some with the 1.5" "T" 's after the 2" "T" 's.

Once the new trailer is here and I start installing equipment to the new trailer, I will do basically the same thing for those rigs but this time I will have a 2" dump valve with a 2" pipe that goes off the end or side of the trailer to empty the tank when needed.

Russ if a pump goes bad and the other machine start sucking air, isnt that something you would notice right away and you can isolate the bad pump? OR would sucking air cause any kind of immediate damage?
I would like to avoid drilling a seperate bulk head if possible.

Yeah you'd notice it right away...your pressure would fall off greatly. If you had each pump ball valved, you could isolate the bad one.
