LS1 fuel tank in an LT1 car

LewisW96 · 09-14-2002, 01:38 AM

I was wondering if the two tanks are interchangeable? LT1 is steel and 15.5 gallons and the LS1 is plastic and 16.5 gallons. The lines and electric conn. look the same.

TIA

Depending on where/how the tank was made bigger, one thing that might be an issue is if the pickup on the pump will reach that extra gallon of gas.

Another thing is that this will really mess up responses to the posts "How many miles per tank do you get?".

(another reason not to ask that question)

My tank has a large dent in it but is not leaking. The gauge also reads fun. I was going to just put in tank pump and al in with the new LS1 tank.

Thats why i was asking?

Good idea! I'm curious, too.

Hmmmmmm........added benefit of the weight savings with a plastic tank!
I wonder what the wieght savings will turn out to be?
When you have both tanks sitting on the ground - see if you can somehow weigh them to see for us.
This may turn out to be a good weight reduction mod if it's quite a bit.......

I am not sure, but I think the LS-1 has a different width trunk space than the LT-1. Therefore, the tank might be formed fit for the particular vehicle.

I'll talk to my salvage guy in the morning and see what he says.

its 16.8 gallons.. if you want to be technical..

:P

also the gauge light comes on in an ls1 when it gets to about 3 gallons left.

In my LT1, the E meant get ready to push. 5 times I found myself pushing or walking with my trusty 1 gallon gas can I kept in the trunk.

I don't know if the low fuel light will come on or not, but the extra gallon or so of gas would be a plus. I not think the wieght diff. is going to be too great. I figured my gauge is bad and I also have a large dent on the corner of my tank. I would be able to fix both in one shot.

Well I think I'm going to try it.

The LS1 in the F-Car uses a "Returnless" fuel system. It has a return but it is back near the tank. It may still work, let us know.

chevyguy3 · 09-17-2002, 11:07 PM

i dont have any experience of my own to back it up, but somebody on LS1tech.com said they weighed both tanks and that the plastic tank is 18lbs lighter than the metal tank

Wow.........that much lighter......... As soon as someone knows whether the swap will work, let us know...

Anybody tried this yet?
