I did the Sniper Kit w/Fuel pump about 6 mo. ago and Absolutely love it, had to work out some bugs but the Holley tech line has been real helpful, my fuel pump seems happier when not letting it get below a qtr of a tank, an in tank pump is always best but I thought I'd try it first. The kit took me a day to have the truck running again. Also I figured out my charcoal canister was clogged so I re routed it to the line running into the frame with a filter on the end...that is as must do mod or replacement of the canister, I was getting fuel bubbling and pressure build up in the tank which will cause flooding and poor response or vaperlocki symptoms if you are running a carb or efi unit. Couple all that with a header and 2.5 exhaust to a flow master to my 220k 2F runs incredible now!
Where did you tie in the charcoal canister?
There is a hard line that goes into the bottom of the canister that is already routed into the frame and I just rerouted the line from the fuel tank to that line with a filter in-between. It's real easy. Quickest best mod Ive ever done.
Are you pulling from canister with the intake or Sniper?
I'd like to know if adding an electronic distributer that I can hook up to the Holley computer so it can control timing advance would be worth doing? If anybody can chime in on experience with that? I currently have the stock dizzy to the best of my knowledge, that does have the vacuum hooked up to the Sniper unit.
Not sure If understand,but I have no lines running from the sniper to the canister now, it's completely bypassed. Im pretty sure there are some threads on mud for the bypass
Has anyone actually put one of these on the dyno? I'm looking at rebuilding in the not too distant future and am still not 100% sure which way to go. Right now I'm leaning towards a 2FE, but again, I'm looking for people to educate me.
I'd love to see a little drawing/diagram of the fuel line set-ups that people are using with and without the charcoal canister... (the entire fuel line system, not just around the canister)
My thinking is that any high energy distributor will be a great advantage over the original dizzy still retarded to smog standards, or even advanced for that matter.
Is the consensus that a dizzy that the Sniper unit interfaces with is the preferred solution?
If the Sniper is not somehow processing gas/air from the charcoal canister then all it really is doing is acting as a pressure relief for the fuel tank?

BigRed gets the Sniper this week:
Sniper 2300 basic kit ordered ✓
@Downey Kit ordered ✓
All I have left is the fuel pump and fittings/hose ECT to order and I'm looking at this Fitech kit;
FiTech Fuel Delivery Kits 40005
When I went to purchase this note popped up:
Part Notes:
"Fuel pump features -8 AN inlet and -6 AN outlet. For use with applications up to 600 hp"
Is this okay??

+1 on this request. I have all the bits and think I have most everything figured out except fuel line and return routing and how to deal with the Charcoal canister. I have a new GM canister (as recommended by the OP) if I need it, but need some solid plumbing advice. Not sure I want to vent the fuel tank directly into the frame

After much recent research on this topic, I would say that consensus is pretty well split between those who prefer a re-curved OEM distributor and those who prefer an HEI type distributor. Both camps seem to believe that a properly setup mechanical/vacuum advance dizzy will perform as well as a EFI processor controlled one. I have the DUI dizzy model that's setup for the 2FE and am happy with it. I do not plan to set up the sniper to control the dizzy.
Yes.
The Sniper wouldn’t care. Other than needing a tach/RPM signal, it doesn’t interact with the distributor.
It does have a vac advance port on it.

Another option for those not wanting to use the Fitech fuel system. My friend @houstonfj40 is using it on his fitech 40 series with good results.
I’ve heard mixed results with the fitech fuel system.

Apologize for being mechanically challanged and asking very basic questions....But, that's what I am...this states.its submerged in gas/yet also says installs under the hood....I'm confused how that works out....lol. how can it be "quiet bc it's submerged in gas" yet "installs under the hood???
Would this replace the last.piece of the puzzle I'm missing...in other words does it replace me.needing a fuel pump kit ect. Thanks
Interesting
