Do you have the pumps staged or no? I've forgotten, do you have a Terminator or Dominator?

Right now they are wired together. I'm rocking an HP so if I have a channel leftover I'll probably stage on 8psi. Would be a real quick redo on the wiring as my fuel relay is in the trunk. Independent feed and 60amp + 30amp pump breaker for fuel needs.Do you have the pumps staged or no? I've forgotten, do you have a Terminator or Dominator?

If I was running a stock injector setup I would have hit the same pressure when I primed up the system. I saw 70psi on my mechanical gauge but I am set for 43psi. I am -8 feed to regulator and -6 return to tank, all braided stainless, so I am not worried about system capacity with both pumps running. The Denmah ran 3 450s in the Colorado without staging on E85, and fed through a -6 line to 800whp, it should be ok for the 2 340s volume. Kinda what guided my thinking anyway.You'll need a lot of return to handle both of those pumps at the same time. I've been using the two pump setup forever with turbo's and unless you intend to run 20+ psi, then you need to stage the second pump earlier, somewhere in the 1-4 psi range because it will take about 1/2 a second to react. The idea being that you won't be in the sub 8psi area for much more than the 1/2 a second that it takes for the 2nd pump to respond.
My friend, professional tuner, thought we could run two AEM 380's at the same time with truck fuel rails. It blew the end out of one at an estimated 140+ psi at idle hehe (gauge was a 120 psi gauge that got pegged). Fortunately it was in his shop and he had another 4-5 sets in stock lol. Somewhat messy and could be dangerous.
If you have a 1/2" return to the tank, then running both will work, but you'll have a hurricane of fuel in the tank which can cause some aeration on the supply side that is a real 'head scratcher' to tune around.
I don't know if this is common knowledge or not. I've never heard about it so here goes. Griffin recommends to have a rubber isolator the whole length of the bottom of radiator. Not just the two rubber pieces. I believe this was the problem with end tanks leaking in the past.
I just ordered the same Griffin...
That is true. It's right in the install instructions. I think it might get a center brace built from another set of stock cushions.I don't know if this is common knowledge or not.
