What year Monte fuel tank do I need?

[t72ss402]

I am collecting the parts needed to place my LS6 into my 79 Malibu, I am needing to know what year of fuel tank that has the intake fuel pump.

Any part numbers would be great.

Thanks Tim.

I suggest to look it up on rockauto.com. Look for the tank for the 4.3 TBI V6.

Ok cool thanks man.

I know this is old listing but a 1987 El Camino came with the 4.3L and would work great.

I got one for a 87 Monte Carlo with 4.3L TBI. You may want to look at modifying an aftermarket tank. Apparently they all have some type of design flaw that causes vent problems while filling with gas. I wished I had known this, because my son's Malibu will literally spit gas out the filler if you fill too fast.

Is the issue due to the baffling in the tank? I believe the baffling is what makes the tank different than a non-FI tank.

An El Camino tank is different than the Monte Carlo tank.

No, the baffling is not the problem. I'm not sure exactly what the difference is, because they look the same externally. I'm wondering if the filler neck goes into the tank further on the aftermarket tanks, which cause a vent problem during fill-up? I know that I've read MANY people complain about having fill problems with these aftermarket tanks.

It's not because the fuel nozzle is in too far like someone said on the other thread. We've tried all different angles and just barely inserted into the fuel filler. Like, I said, it will spit fuel 2-3 feet out of the filler if you attempt to put fuel in at full speed.

I even dropped the tank to make sure the vent line wasn't bent or kinked. I believe there is a design flaw in the aftermarket tanks. I'd suggest trying to find an OEM from a TBI Monte Carlo or Buick GN. Or, take the aftermarket tank to a welder or radiator shop to have them install a vent setup like samh_08 did (or do it yourself). Just be sure to modify it before you ever put fuel in it. I know, that's a no-brainer...

I ended up modifing the stock tank with a sump and using a external fuel pump. I will post pics soon.

I was looking at some G-body swaps on LS1tech and I think this guy found the problem with the aftermarket tanks not venting correctly (read post #26):
