All,
I have no plans to start a fuel pump war just relaying what I think is good information. I just had a conversation with Chris at Walbrofuelpumps.com. He said they make a fuel pump specifically for the LS engine/FJ62 tank. Here is the link. and I will post the transcript of our conversation.
Walbro TCA324HP High Performance Fuel Pump Kit from Fuel-Pumps.net

David:
Hi,
I am looking for an in tank pump that produces the 58 psi an LS motor needs. I am putting a GM 5.3 engine in an
80s landcruiser and want to use your pump in the stock module.
Call accepted by operator Chris. Currently in room: Chris.
Chris:
Thanks for writing, David. What year is the Landcruiser?
David:
1988 FJ62. Do you have a repair kit that has the pump, sock and electrical pigtail?
Chris:
Let's see. One moment.
Chris:
The OE replacement pump for that Landcruiser is called a TCA324. We sell a version with the 255 LPH
high-pressure capable pump called the TCA324HP.
Chris:
It includes all of the components you need to install this on your Landcruiser. Cost is $142.25 delivered.
David:
What is the pressure rating?
Chris:
It is more than adeqate for your LS engine. Well over 58 PSI
Chris:
This pump/kit is specifically designed for what you are doing.
David:
Sorry for the skepticism Chris, no reflection on you.
Chris:
That's because they are dealing with other distributors who don't know what they are talking about.
David:
Ha!
Chris:
WalbroFuelPumps.Com is only one of our websites, actually. Let me send you a link to another: http://www.fuelpumps.
net/tca324hp.html
Chris:
That is the _exact_ fuel pump kit for your application.
David:
So the TCA342HP will fit into the stock pump module?
Chris:
The pump in the picture is the OE pump but we replace it with a Walbro 255 LPH pump that is the same size. We
include a harness pigtail to connect to the 255 LPH pump.
David:
So easy.
Chris:
If this doesn't work perfectly for you then send it back and I'll give you your money back. But if it does work
perfectly then I expect every Landcruiser dude on the face of the planet to be coming to us buying that fuel pump.
Chris:
(But that is up to you to let them know!)
David:
You have no idea. Wow. I will do that now. My swap begins in three weeks. Is that one in
stock now? And it's a genuine Walbro?
Chris:
Genuine Walbro, in stock now.
David:
Chris, you made my day. Thanks.
Chris:
Glad you stopped by. Let me know how I can be of further assistance, David. Have a great day.
David:
You too.

Very cool. Now let's see if it's really true.
 
TCA324HP ordered and tank pulled... let’s see what happens.

I’m about to swap 5.3 into my FZJ80, and the fuel pressure question came up. How did it go for you, cruisermatt?
 
I'm running a 1FZ pump now. The Walbro I got from them was DOA. Hook up your 80 series fuel lines to your 5.3 and party. Get fuel rails with a return fitting and run a manual FPR in your return line back to the tank.

Thanks for your fast response. Doing a 5.3 swap and wanted to get the fuel pressure right.

Hey Matt. I'm excited to use your engine mounts. I already cut off the LC brackets. Can you elaborate on your setup and please share the parts.
I read on other swap they used the walbro gsl392. Are you saying you are using the stock 1FZ pump? Be great if you can share some pictures of
your setup. Appreciate it man.
 
I went through 5 Walbro External pumps on my 5.3 swap, they kept burning out. Switched to the generic autozone and my problems went away
Wow. That sucks man. Thanks for the tips. Did you hook up an external fuel filter and can you please share the fuel pump you used.

I've learned since this thread that pretty much any EFI pump is fine for stock 4.8/5.3/6.0. I've ran several with the stock 62 pump since then.
Mine is still a Denso 1FZ pump, just have to change the connector.
I now have a turbo so it's on my short list of projects to completely revamp my fuel system to support +500hp

Sounds like using the stock pump seem easier than the walbro setup (do like it's internal versus outside the tank). I can use the supra pump right? And, do I need to use the corvette fuel filter to regulate the fuel pressure with supra. Reading online you just need about 60 psi of pressure for ls swap. Thanks

You can use any in-tank pump you want inside the tank, you may just need to adapt the electrical connector.

Fuel pump doesn't create pressure. They create flow. The fuel pressure regulator blocking the line is what creates pressure. When a fuel pump "can't make enough pressure" what is happening is the pump isn't flowing enough fuel to keep the pressure high enough to meet the demands of the injector's.

As to whether or not you need a separate regulator or not, and what style (return vs returnless), that is going to depend on what fuel rails you have.

Thanks for the detailed clarification. You're awesome.

The third one just died on me in our way to a wheeling trip, picking a generic pump at Oreillys and see how it goes
 
I think I found what killed the fuel pump…. I have a filter befoand a filter after the pump, I blew out the “before” filter and this came out, looks like a piece of latex glove

Are the FJ62 and FJ60 fuel pump brackets the same? I am still having fuel delivery issues (new Oreillys inline pump & fuel filters, new aeromotive fpr) with my 60. While looking into the issue I found the my 60 has 2 fuel pressure regulators, I still can’t get more than 42psi for about 30 seconds and then, pressure drops. Thinking of eliminating the Aeromotive and just running the manual one with in tank pump instead of inline.

Return style doesn't need anything but the gm fuel pressure regulator so you can remove the aftermarket one and no the 60 and 62 fuel pump module are not the same.
