Please also bear in mind that experts can also quite easily overlook the basics.
They are more 'in-tune' with their CHEVY ENGINES......

This is the basic layout, the 2x4 doesn't have the internal regulator like the single unit does so the plumbing is a little different. I would mount the regulator as far to the front/nearest the TBs as possible.

Interesting, I know they prefer to position the regulator after the fuel rails on a port-injected system..but I've never done it that way with the TBI kits and things worked fine. The standard Sniper, yeah the return line was plumbed directly out of the throttle body unit but it had the internal regulator.View attachment 1520013
I was told that 'Dead-heading' is not recommended for the Holley Sniper setup. The fuel needs to flow through the throttle body(ies) for cooling as well as maintaining fuel pressure and flow.....that is - having a dedicated Return line from TB to tank.
I thought I could get away with that also....but it won't work. The result was fuel starvation. I would be interested to know if the OP has done this as per your diagram @beanhead
I think the standard Sniper unit with its built-in regulator is more susceptible to any fluctuations (Hey I know a joke about that) and large differentials in fuel pressure & flow. IMHO Dead-heading would be a factor here.Interesting, I know they prefer to position the regulator after the fuel rails on a port-injected system..but I've never done it that way with the TBI kits and things worked fine.

Of course, I've not done a dual-TBI install(yet!)
Which is why I said dead-heading should not be done.Choking down a hugely oversize pump is going to make it hard work on the regulator.
