Will do buddy. If I have time I may try the swap as soon as this weekend since it's a Holiday.

i have been wondering this ever since i found out the LS1 had a plastic tank. i was just unsure about the weight savings because of thick plastic and larger capacity. however, with the new light shed that it is an 18 pound difference, i am really wondering if it will work! this would be one of the next mods!

 

Ok, heres the deal on the tank according to my interchange at work.

93-97 regardless of engine size fit each other, camaro and firebird

98 camaro and firebird only fit 1998!!! nothing else

99-2002 fit regardless of engine with each other firebird and camaro. The dimensions are different, so I would doubt it would fit. Personally I think it is a bit of a headache to make one work to only gain a gallon and a half. But have fun, hope the info helped

Q

 

its not the extra gallon, its the weight

 

I think one of the differences in the 98' from the 99+ tanks is that the 98's have the FPR in the fuel rail when the 99+ have it on the tank.

 

not all ls1 have plastic tanks I think 98 still have metal. Yes you can just plumb the plastic tank. The www.horsepowerstore.com did it on there car.

 

Did anyone do this yet?

The new tanks have the regulator on the tank?

Don't make me be the first one dammit!

 

Go for it.....I've been waiting for someone to try this.....

 

93-96 have low gas lights????¿¿¿ Maybe a low oil light

 

I need to know what the difference is with the fuel lines and the regulator/Pumps and if they interchange.

 

Anyone know if the number of lines is the same between the LT1 and LS1 tank?

 

Someone do this already before I have to!!! Also, how much can the tanks be bought for out of a wreck on average???? Sounds like a cool weight-reduction mod once I do the BMR K-member and control arms.

 

TTT

 

I have a 98 tank froma wrecked car and the tanks is metal. Weight felt the same as my 95 when I moved them from point a to point b, (NO Scales). The pump of the 98 had an extra set of wires and the plastic line connectors were different. The charcoal canister is different from the 95 and 98 also. 98 is rectangle box and my 95 is round. The 98 also has a regulator in the tank on the pumo assembly. The plastic bucket and tube assembly was different as well.
I am only speaking from my experiance from striping down a 98 Firebird LS1 and working on my 95. I also called a dealor and they said the part #'s were different between the tanks. James

 

so what about the 99 and up tanks?
