It looks a lot like the EZ-EFI except it has a fuel pressure transducer and uses a tablet to do the tuning via bluetooth. I think that's a plus and a minus, it appears it is a little less self tuning than the EZ-EFI, but at the same time it sounds like it has a little more tuning capability than the EZ-EFI, not sure yet. It also sounds like the injectors limit it to 500 hp and they don't plan on anything bigger.

It does cost more with the tablet, $2200 without the fuel system. Not sure if it does timing either, no instructions out yet and not available quite yet.

I was really hoping it would be alot cheaper setup... Nope. Guess Ill keep dreaming

Just for fun... the 68.

NICE Dean....

looks very similar don't it?

The 30226 system I don't think includes the fuel pressure regulator from FAST...thats another 117, so for a little over 1700 I can have the FAST system...plus fuel tank, pickup, fuel pump, lines, fittings, etc....that's what adds up, sure you can get the "system" for under 1600, but installed and running is probably 22-2300.

If I get the Walbro 255 in tank pump does the fuel pump wiring/relay (whatever it needs to work with this system) go to the EZ-EFI brain box, or plug into the sending unit or what? Not understanding how the pump/sending unit setup works with the EZ control unit.

 

[folkenheath]

The ez control unit will turn the fuel pump relay on/off when it needs it. If you get a round dual weatherpack connector it will plug right into the factory sending unit. The pump kit will come with a connector adaptor. I used it because I was afraid to put regular wires submersed in the fuel. You can plug the walbro pump right into the sending unit. But then you will need the connector to wire the ECM relay to that connector to plug into the sending unit. (one wire will be pump positive from the EZ fuel pump relay, the other wire will just go directly to ground).

Here is several connectors, maybe you can find one, but I used them in other locations as well...

Then you will need the adaptor fittings if you want to convert the lines to AN...

Here is mine (you won't have to flare the fittings since blazers have o-ring fittings)

[folkenheath]

Also, the fuel line that comes with the walbro pump, don't use it, use this...

http://www.oreillyauto.com/site/c/detail/GAT0/27093.oap?ck=Search_27093_-1_-1&keyword=27093

If I had access to mine I would lend you some, you only need 4 inches or so but my leftover is in another state.

It sounds dumb as h3ll, but the hose that comes with the pump is NOT rated for submersible use. Many have gotten away with using it without issue, but some haven't, and I don't trust it. If that line bursts you are SOL until you drop the tank and fix it.

 

[NorCal69]

Well Heath, It looks like you wrangled someone for the Fast System..

I'll be watching this one.

 

[folkenheath]

nice binocs!

I think he's at least the 5th person on this sight to go with the FAST EZ setup now, right...?

And Mike your 69 is old enough you can use the FAST system without worry of emmisions there right?

It should be once you go fuel injection you will sit there every time you start it drive it, wheel it, look at it. And say why didn't I do that sooner!!!!

Dam Heath, one stop shopping, I like it! thanks man!

I got some fuel submersible rated hose but will have to check the pressure rating for it, might not be high enough.

It should be once you go fuel injection you will sit there every time you start it drive it, wheel it, look at it. And say why didn't I do that sooner!!!!

that's what I'm hoping for....something to think about:

say I'm sitting on a climb like this, or Chewy, or Potato salad....you get the idea....when I was having trouble with the carb, now if I only have a central stock FI pickup point and a 1/4 tank, I can see having problems...and as much as my engine likes fuel....3 gal/hr last time on the back side of the trifecta, I can see having issues later on in a trail run.

 

[blazinzuk]

yah its possible, when I ran out of gas on Chewy though my tank was basically empty.

I think the fuel injection might improve you consumption too.

I know guys with 454s that I wheel with and they never have problems running out of gas even after a day

 

[folkenheath]

I agree with Eric, I've never been on those obstacles, but I have been on several angles under all throttle conditions and never had any issues.

I've also gone full throttle all the way up test hill with only a quarter tank and didn't have one hiccup, I did fill er up shortly after that because I thought running on a quarter tank was pushing it. The stock baffle pan works pretty well, and honestly, I don't think you will be able to make anything that works much better and is reliable in all conditions for the purpose you need it.

You thinking 31 or 25 gallon? The 31 would be great as long as its not in the way.

If you are going to be idling a lot, you can turn your idle A/F ration down with a few button pushes. You can do that to the cruise(part throttle) A/F ratio too without effecting WOT. Its so easy its not even funny.

 

[76zimmer]

Eric, you know what I'm talking about when I was trying to make it up Chewy and Potato Salad...the stalling drove me nuts, I know when we dumped that 5 gal in your truck you didn't have any problems that I saw on Pritchett.
I'm going with the 31 gal and will make room for it, my upper tank mounts on the frame will have to go, as well as the rear floor section above the tank to make room for it....I still want to keep it high in the frame and use my kickass tank skid made at DIY4X.
I do have an issue with the flange on the tank mounting it that high, the flange has to be folded up to clear the boxing on the frame, I'll have to work that out again.

 

[rdn2blazer]

Just for fun... the 68.

That is a thing of beauty!!! I had a 69' short bed bright yellow, lowered with a nich 350 small block. Man do I miss that truck. I want another short bed some day.

 

[Deuling]

You wont be able to use your fancy quad fuel pickup? Couldnt you just use the carb tank and keep that setup in there and hook it up to the FI sending unit and not need baffles? Just thinkin out loud.

 

[82355]

In my '90 K5 the ONLY time I have ran out of fuel and stalled was when I was on an extreme downhill angle, and my tank was on E.

He could but the high pressure EFI pump should be on the bottom of the tank if possible. And any restriction before the pump is not good, any restriction after the pump isn't as critical because of the high pressure.

Also, although that fancy super duper double triple pickup tree looks like it would solve the worlds problems, I am not convinced it isn't part of his stalling problem until I see it proven otherwise. I trust the factory setup more.

 

[Deuling]

To me the quad pickup would be the opposite of an obstruction i guess its more lines and such bit its 4 not one so it should allow lots of fuel easily in my mind. Stalling on an angle to me seems like a carb issue but i cant say for sure. But if your gonna buy a new tank anyways you may as well get the tbi one. My thought was to be able to keep the tank he has and save money instead of gettin another tank.

 

[folkenheath]

I'm not worried about the restriction Adam, the problem is how reliable are those pickups? With 4 pickups you have a much greater chance that one of them will be sucking air when at any angle or acceleration. How reliable is it at shutting off when not submerged, and how quickly? Because if even one can suck air then it will have no suction for the other 3. It would be like trying to suck through a straw with a hole in the side right above the liquid level.

Thats a great point heath. Single pickup with baffles does sound mich better now.
