getting parts for efi kit

The reason we use the TBI tank is two things...

One is that we can use oem stuff and just use the higher output pump...makes it cheap and easy to get parts if need be.

The other reason is the pickup/baffles. With an out of tank pump you'll need a pickup tube that reaches the bottom of the tank for feed.

Maybe with a carb tank the pickup is OK but the lack of baffles opens up fuel problems if say you're low on fuel and a little off kilter...you'll suck air because of the higher pressure.

I bought my tank off summit for $99...it's a 31 gallon. I got the sender from rockauto for $70. Pump was another $68 I think...from summit.
 
You could also scrounge around and see if you can find an '87-91 K5 being parted out, and grab the sending unit/tank from it. Used tanks are a crapshoot because the interior baffles are plastic and break (from what I've seen, seems to happen when the vehicle comes to an abrupt halt, like hitting another vehicle) but the factory design is actually much better than what Spectra has been selling. So if you got lucky and found as used one with a good sender AND baffled factory tank, you'd save yourself a bunch of hassle. You will already be dropping the tank (I would think, unless you plan on cutting the floor) so mightaswell swap the tank at the same time.

Anymore the yards punch the tanks, but private seller normally won't.

Senders are fairly robust, but they do fail. They sure have come down in price in the last few years.

Interesting. The baffle in my tank is metal and literally is one of those tinfoil lasagna pans lol. My tank is new though...

Ehh, it sounds like even some of the higher end pumps aren't as good as you'd expect, as with everything else nowadays, it's a crapshoot IMO. My experience with an external pump was that it was noisy. There are other potential issues with them, IMO the main one is noise. There are probably quieter ones, I just haven't had experience with them.

ya i thought about that too plus it wont work tanks too deep

You did make me think about taking a TBI truck sending unit, and modifying it for other GM apps, cutting it to the right height, maybe coming up with a small sump/baffle setup that is welded to the pickup. Problem with that is it would add a lot of stress to the tubing when fuel sloshed, which would be even more a problem with the large K5 tanks, and long truck tanks.

Basically, what we want/need is one of these, designed to replace our stock sending units:

Keep everything steel, brace the sump/pickup/pump area so it doesn't break off from fuel sloshing, and you'd not need a new tank. Even at ~$150-200 it would be worth it. AFAIK that design "slides" on the three steel rods, so useful on various tank depths.

Sorry for going off-topic a bit, just wish someone with the resources would build it. It would work well for you.

That piece of shit. Ive never had so much trouble with a vehicle in my life until i met one of those plastic pieces of junk. I knew every tow truck driver in the county when i had one of those. Never again. Never an OBS style again.

Fitech fuel control centre looks interesting. You can have a conventional electric inline pump run fuel from your stock tank to the fuel centre. I did read that the control centre still needs a return line to your factory fuel tank.

If you have a conventional inline pump why run the fuel control center? Upgrade your pump and be done with it. If you wanted to keep your stock fuel lines and mechanical pump I see the advantage, kinda. I don't like having a fuel tank up under the hood personally.
 
i just dont like the idea of fuel tank unit under the hood and 2 pumps 2 possible failure points.
that other link i mentioned they can make one that will fit the depth of our tanks, and its $245 for everything it needs just have to get fuel line
 
Personally the command center is no more dangerous than running 60psi of gas through a rubber line on a truck.

Its a difference of maybe $100 to do it the way im doing it, which is safer.

It may be less then that. I ended up buying fuel line a bit longer then what i needed and i have a foot on your wheelbase.

The Fitech kit also doesnt have a return line hose...Just 20ft of supply.
