47-55.1 Under bed gas tank with side feed?

[vintovka]

Ran mine as shown. Fills nicely with no burps. Used a stock 25 gallon k10. Having a 4" lift allowed filler and breather to easily be run over frame with only a small inner bed cut. Easily fills and takes locking cap just fine. Only 2 regrets. First was not assembling bed completely before tank install as reaching one row of bed bolts is going to be hard. Second the 25 gallon capacity is nice but at near $6/gallon very painful.

What does a tank need to be to be LS ready?

EFI/ High pressure/ pump inside tank?

When looking at these older variety tanks what should I keep in mind
for making the tank work in my favor?

This C4 issue of not to much room to dump the exhaust out the back end is a concern to me.

A tank with internal baffles around the pump or the pump inside a bucket
a pump that can maintain something like 55-60 PSI
fuel return line
vents, filler, fuel sender
Either a filter with pressure regulator or a fuel rail with built in regulator or a separate regulator
Easiest way to get all that is use a GM EFI tank.

If the tank has a standard GM fuel pump opening you could use a autoparts store pump and drop it in.
You can also buy pumps setup to fit into old school style sender openings: https://www.tanksinc.com/index.cfm/p...rod/prd227.htm So you could use an old tank or repop old tank but you might suffer slosh induced loss of pressure when the tank is near empty

Or coble up your own mount plate with vents, return etc.

There are external pumps sold to work, but they all have bad reputation of not lasting. Internal pump is the standard.

The pumps themselves are something that has suffered from import junk clogging the distribution system. The internals of the pump are nothing special, but with so much cheap stuff out there it is hard to find a good pump economically. I have not dropped the tank on my last swap to stick in the $200 genuine Walbro, so far it is running great on the $50 Acdelco brand pump designed for a pre LS era 2.2 that I put in a year or so before the swap. YMMV dropping full tanks to swap pumps is a pain.

I agree with the hassle have known some guys as well as myself that put a brand new one in got it all in place and it was defective. That can be very, very discouraging depending on how hard it is to get to the pump. My kit came with generic brand Chinese pump and I just couldn’t bring myself to put that thing in there even though I designed my tank to drop out the bottom. Can sure cost more, but i’ve been trying to buy as much USA as possible so I went to the Aeromotive in tank pump. Great reputation, they will talk with you through the installation, it’s what they do, so good at it.

Any GM EFI/TBI tank can work. Then it will be baffled, have return port, breather and can take a combo pump/sender. Then, say an in-tank Walbro or Aeromotive pump for longevity. In the tank, the fuel surrounding the pump will run cooler, so minimize the challenge of " how far can I go on this tank". It shortens the life of the pump.
I just went for the 'Tanks' 50 Chevy for size, EFI ready, custom sender capable for the Bosch gauge and filler location... and it was about the same as anything else new. I think cheaper than what some are charging for the custom between the frame aluminium AD Chevy truck tanks.

I purchased a Boyds Welding LLC 63-72 Side fuel tank, set up for my EFI,
this is on my 58 Cameo and planning on filling just behind the Cameo Taillight
to gain access to the gas fill.

You might want to look over there tanks to see if one will work for your truck?
Happy with mine so far!

Forgot to say i am using C4 Front and rear on my truck also with Flat Out Engineering kits.
For what its worth.
