I going the same way that Philip and Mike did with an in-tank pump. Doing a 6.0/4L80e swap in my 72. I did install the "sock" prior to installing the pump assembly in my tank. Using Bosch pump 69225.

Hey George, because the fuel pump or it's pickup needs to be immersed in fuel all the time, I usually recommend something like the Aeromotive Phantom setup that places a foam bucket around the pump in the tank.

Here's what I ended up doing. It's a stock non-return ZL1 pump good to 900hp and a VaporWorx controller powers it. Red circle is a Tanks Inc. tank vent I hosed to a charcoal filter up behind the bumper.

Dennis, what brand of in line pump are you using? Inline pump would be less trouble than a in tank pump. If it isn't really noisy. I don't like noisy pumps.

Thanks

Eric
It’s a Holly pump. I mounted it with the isolation clamps which is important.

The shape of the tank makes most of the aftermarket pump systems unusable for a wagon tank. The good thing the shape of the tank works well without the need of sump in the tank.





Here is a stock fuel pick up next to the modified one with a pump. The tube was bent to allow the pump to set vertical in the tank with the strainer on the bottom.

THe wagon tanks are a lot different than the car tanks.

The in tank pump setup in my Tanks inc pump works ok, but for racing (which is primarily what I do), there has to be over half tank of fuel. If not, it runs out of fuel at the top of first gear till i hit second and the fuel moves back to the front of the tank. Wish i would have known about this before buying the tank...I looked into getting the farm from the phantom setup, but don't think they are selling it separate.

Philip,
the modified one, did you buy a replacement sender unit and modify it? Or did you have a spare original unit?

In process of doing the swap on my Cutlass, bought a Aeromotive Stealth II tank for it with the 340 pump.

I think it's going to be much better than Tanks Inc. setup that I have on Chevelle, and it was couple of $$ cheaper. It came assembled and ready to be dropped in. 6an supply and return.

I have a spare tank and sender. AFAIK wagon tanks and sending units are not reproduced.

I did something like Philip using the Delco EP381 pump. The goal was to use as many parts store available pieces as I could. I haven’t road tested it yet, and it’ll probably be any other month or so before I do.

That being said, I don’t love having a fuel tank outside the rails so I am seriously considering using an El Camino tank from a tanks inc or equivalent. It will mean cutting out the storage area under the floor, but I’m OK with that.

I should have some pictures in my signature of what I did, but like I said, it’s a lot like what Philip did.
