OK so I can use my stock FJ62 steering wheel, steering column and the gear box with no problems right!...
I am not a rock crowler anyway so should be plenty strong for me

Fuel Pump Mania
One of the few non-Toyota parts on Da'40 is the fuel pump. I've already had one strand me. A few years ago Ryan told me there was a Toyota external fuel pump application. He thought it was used on early Celica cars. After my tow from Daisy, Ryan said it again, so I thought I better look into this application. Between the EPC, the U-Pull boneyard, the Fast Moving Parts catalog, and Dan this is what I have learned.
The external fuel pump was used on 1983 Celica GT and GTS with the 22RE engine; on the 1982-83 Celica Supra with the 5MGE; and the 1981-84 Cressida also with the 5MGE. The pumps are sold with the mounting bracket, which means three part numbers. The Celica GTS and the Supra are the same part number. As best I can tell the Celica and Cressida seem to have the same pump, but the connectors are different. The Celica connector is under the body and is a sealed round plug. The Cressida connector is mounted in the trunk where it's away from the elements and is an unsealed OEM t-connector.
All the pumps have a 1/2" input, and a banjo fitting into a 5/16" flare nut high pressure output. The high pressure hoses are the same on all the Celica cars. The Cressida uses a different hose. The hoses swap and the difference is the direction they point coming off the pump.
The U-Pull just happen to have a selection of Celica, Supra, and Cressida, and all of the pumps came home with me. Two of the pumps were aftermarket replacements. A third might be as well. Either that or the pump went through an evolution in 1984.
The brackets for these pumps are well insulated. The pump mounts to a ring which has a pair of rubber isolators on either side. The bracket it attaches to also has three rubber isolators. This bracket attaches to the body.
For my application I decided to modify the bracket from the Celica GT. A little cutting and drilling, and I had a flat bracket with three isolators. This was attached to a piece of 1/8" that will be mounted to the rear cross member with a pair of muffler clamps.
For plumbing I used the high pressure hose from the Celica. In the pic I show a Cressida pump with the Cressida high pressure hose. The Celica hose points the other direction and fits my application better.
To fit the pump I will need to make a new wire harness because the one on Da'40 now is too short (currently uses the OEM round plug). I will need to make a new 5/16" high pressure line because it is too short and it needs flare nut fittings on both ends instead of just one. Last, the supply on the tank is 5/16". I have a 3/8" fitting for the tank, so I will need to adapt from the 3/8" to the 1/2" on the pump using a barb adapter.
Some reference numbers.
Cressida, 23210-45060, $525.83 list.
Supra and Celica GTS, 23210-43040, $610.56 list.
Celica GT, 23210-35010, $493.13 list.

Can you see a quality difference between the aftermarket and the OEM fuel pumps? Are the aftermarket pumps still available?

I don't know if the aftermarket pumps are still available. Dan said the OEM is. I just went out and looked at the aftermarket pumps again. Three pumps are aftermarket replacement. One was not very good and hit the trash. The other two are marked "made in the USA" and looked solid. One was nearly a copy of the OEM. The two USA pumps are also about the same diameter and length as the OEM, where the third was smaller.
From left to right: the pump I'm using in Da'40, OEM Cressida (ND), aftermarket, aftermarket. I didn't see any branding on the two pumps on the right.

Do some of these pumps come with a built in check valve, can you tell?

The pump I bought from Summit for Da'40 does have a visible check valve. I can't see anything on the others. I would hope they do.

More gas. Single can holder is finished.
They would have to have a check valve otherwise you'd lose fuel pressure and be starting a dry pump with every turn of the key.

Jon,
I had the same problems with my Vortec until I finally gave in and welded the fitting for a factory pump to the top of my second tank. Now I run a Chevy pump, and it has run like a watch for 6 or 7 years. What about welding the fitting from an HJ62 tank into the top of your tank, and then running the facotory FJ62 pump? Do you have the room at the top of your tank?
Cheers,
Josh

Are you talking about an in-tank pump? I'm sure something could be fabricated. The tank is deep enough and I have plenty of room on top. I'm not sure how the baffling on the tank is set up. At this point I'm content with the external. I just need to make it Toyota reliable.
On that front. I'm working on another idea for mounting the OEM pump. I'm also going to use the mount above, modified, for the generic pump I have. Hopefully it will make it quieter.

I run the 2F mechanical pump to lift from the main tank to a surge tank and a Bosch electric pump in a loop to and from the surge tank. It has been very effective and no fuel starvation even for my thirsty girl with the mechanical pump.
No high pressure lines to and from the main tank either which is a bonus.

Just went through some fuel pump problems myself and ended up using an Edelbrock Quiet-Flo #350-1791 and it works great! I first tried the Summit racing version and went through 2 of them in a month, both had leaks when I first got them (had to repair the misaligned gasket) + they sounded like I was drilling for oil as a drove down the road. The Edlebrock has a built in adjustable pressure regulator thats preset to 6.5psi and is actually very quiet!
I think Jon's playing with something like 40 psi.

Correct. Toyota efi needs 45psi.
External has the benefit of being able to do a filed swap in about 5 minutes. All the internal pumps I've dealt with involved dropping the tank.

I remounted the fuel pump. This is the aftermarket pump, but the Cressida pump I'm going to use will be an easy swap off this bracket (four bolts). Main bracket is a 4x8" piece of 1/8" attached using muffler clamps to the crossmember. I installed four of the rubber isolators from the Cressida bracket into a piece of 4x6" 16 gauge sheet metal. The pump mounts directly to the sheet metal using #10 screws that are welded on the back side to the sheet metal.
I thought this would make things a bit quieter, but I think I was wrong. Maybe a little.

I wonder if four vibration dampning mounts would work? Something like on this page McMaster-Carr
Just a thought.

I took Da'40 to Ryan to see if he had any ideas on the chirp under the hood. We couldn't figure it out. On the way there I noticed the pump is much quieter while driving. I do hear it when standing at the rear wheel, but it's much better inside the truck.
I've seen those mounts at McMaster-Carr. One of the mounts they sell is very similar to what I'm using. This is a temporary deal and I will adapt to the quieter Cressida pump when I get back from Moab. Toyota only uses three of those mounts with their pump. I'm using four. Plus there are two more dampers on the Cressida pump. See pic.
