Hello fellow hotrodders. I am in the process of collecting the parts to put a 2000 5.3 ls motor in my 67 suburban.

I have been looking for an in tank fuel pump to no avail. Does anyone know of a pump that is small enough to fit into the stock type gas tank, that will provide the high fuel pressure needed (45-50 psi).

My gas tank is from Brothers Truck parts.

I'm trying to avoid the noisy external fuel pump and the expense of a modern fuel cell. thanks.

There are new inline pumps just for this. You can always cut a new hole and make a mounting flange for the in-tank pumps. Shop Summit racing for a pump, and while you have the tank out, figure out where the return line is going to enter at.

Thanks Joe. I probably should have figured that out BEFORE I installed it and filled it with gas!! This one comes with "extra" hose attachments... which I assume can be used for the return line.

Made my own with an OEM GM pump. Not hard to do but you must use fuel resistant hose. The last pic is when I learned about those hoses. No problems since!

No problem with gas residue in the tank, just hook a flex hose up to a tail pipe and let run till tank is warm to the touch. You can then cut/weld/solder with no danger. We usually just cut the pump mount flange out of a donor tank and braze/solder it to the projects tank, this keeps the pump and mount together as a pair. The gauge sender will not be correct so a separate mount for an aftermarket sender is used. Pick a donor that uses the same pressure you need.

If you do use the sender, mount it pointing the correct way, same as the stock one.

Mark, that's some ugly fuel line you have there, I remember your comments awhile back about fuel line. Guess that's why GM went to the plastic type line.

Looks like you should be able to hang a walbro 255 pump on the stock pickup and set it so the sock sits flat on bottom. Just have to fold the sock on the way in. Ive done a bunch like that. I did find one thinner pump before but I will have to go back and see if I can find info on what it was from.

Ive seen those plastic accordion type factory hoses from the pump blow off about mmmmm 5 times on different trucks so faršŸ¤£. It was my dads truck once. I always zip tie them before I put a aftermarket one in the tank because they are just a press fit. Must be faster and easier on the assembly line........then screws ya later as always.

I know you purchased your tank from Brothers, they offer a kit to convert to an in tank fuel pump for EFI. I'm surprised they didn't tell you about it when you ordered yours. (http://blog.brotherstrucks.com/in-tank-internal-fuel-pump-installation-chevy-gmc-truck/)

Evan, I use either Nitrogen or CO2 gas as a purge when I'm welding or cutting on fuel tanks. Set up a pressure regulator at a slow constant flow into the tank and lei it run for a couple of minutes to displace all the oxygen.
