Fuel Tanks: TBI Vs carb for EFI conversion
- Thread starter GMC500
- Start date
Really not much comparison. They make carbs that will work better than stock on inclines or rough terrain, but eventually they will fail
Tbi could keep running upside down if the fuel pump could get fuel.
Of course, then you run into problems with your lubrication........
However, unless you are really going to extremes, most carbs will keep on going too.

Looking at your question again, I'm not sure if you are looking for comparisons between TBI and carbs, or tank and pump combinations.
Ignoring the final delivery system, there is not a lot of difference between inline or tank pumps as far as inclines or rough terrain.
As for the tanks themselves, most will deliver fuel at most any reasonable angle if kept close to full.
If you are low, and tilt the tank, the fuel may run away from the pickup.
The baffles will not do much for that. They have holes in them to let the fuel move around in the tank, so the tilt would starve the pickup anyway.
Baffles are for slosh prevention to help stabilize a truck with a lot of fuel, and to prevent air bubbles from getting into the pickup.
But if you are running that hard, you are going to have problems staying conscious anyway......

I apologize for my question not being clear
I am planning to do EFI conversion and I am comparing the two alternatives
but since most baffles break in TBI tanks, I think that I will stick with the normal non-baffled tank
thanks a lot
I have a TBI tank ( cause well I have TBI) and I have kept running at some pretty decent angles nearly out of gas.
On the other hand those same angles starved my blazer tank ( carbed tank) when it was at the same level.
This was on the same trail on the same obstacle.
My baffles have not broken off

The tanks from EFI trucks do a better job at preventing starvation, so if you can find a good one, that's the way to go. For aftermarket tanks, there are various configurations, most of which perform worse than stock, but have welded steel baffles. The one I have just has like a little pan under the pump with small holes at the bottom. It starves the TPI under accel/corners in the last 1/8 of the tank. It's really not that bad - I just need to have more gas in the tank when wheeling and have a reliable "early warning" system that it's getting low. My car has great baffles but it just dies in traffic with no warning and needs like 3 gallons before it will start again.
Definitely go with the baffled tank if using any kind of electric fuel pump. Take it from me, I ran an inline pump on a non baffled tank and below a half tank I would encounter all kinds of fuel starvation issues due to the sloshing effect. There is no comparison go for a baffled tank. New tanks are only $100 anyway, its a good investment.
X2 They are baffled for a reason.
