Setting up a Fatboy & Accumulator Tank

This is a first for me (I have zero experience with this equipment). I wanted to get it setup, or at least get the materials today, but I have a couple of questions.

• How close can the accumulator tank be to one side of the pump and how far away (max) can the chem tank be from the other side of the pump?

• I plan to use a 5/8” chem line for this setup but I was thinking about running 3/4” line from the tank to the pump. Will that be okay or should I use a bigger line on the input side of the pump? The thing is, if I go any bigger with that line it would have to be reduced at the pump anyway?

I’d appreciate any help I can get, to set this pump up right - the first time.

* This is (almost) a duplicate of a thread I started on another forum today, but apparently those folks are out making a living!

TIA
 
:yikes: My tank came set at 50psi.

As far as the line goes, I'm basing my decision on several threads about that pump lasting longer when using a 5/8 chem line. I've also read that some guys are going to 3/4 line, but I'm not convenienced the 3/4 would make much difference because you still have the 5/8 bottleneck in and out of the pump. The 3/4 on the inlet side makes sense because there's no pressure involved, so it's just flood factor.
 
3/4 intake hose for me, 1/2inch spray hose 200ft.
 
I'm liking the sound of that 1/2 line more and more, especially since I can get it locally. If I go with that, will 40gpm nozzles be okay?

Thanks for the replies!
 
I got mine from Bob as well and I have to admit, he sounded a bit surprised when I told him I wanted to go with 5/8 fittings for the pump.

I'm glad I posted this thread here and I appreciate all the advice! I'm going to keep things simple and go with the half inch.
 
I just put together a 12 volt system today. It has an accumutator. What do they do???
 
It is like a bladder that fills with chemicals. That gets drawn from first and it empties, once that happens the pump will kick on like normal. Because of this the pump will cycle less, especially when using small nozzles and when only opening up your chemical line for a quick touch up spray for example.
