82 stepside. Thoughts and crazy ideas

Overview Gallery Discussion
So after a few hours of searching I think I found what I need to make a high flow tank selector.
Screenshot_2020-12-28-22-53-37.png

It's rated for 6 gpm (360gph) and supposedly 3000psi :eek1:. I only need 15 psi :haha: so safe to say it'll handle what I need it to do. It's actually meant for guys running a waste vegetable oil setup with dual tanks.

The part that sucks, they're a 100 bucks each and I need 3 of them :doah:. But they should work exactly how I'm planning them too.

So 300 bucks for those valves, 650 for a fass unit. Ah, nothing like having to spend just under a grand for an awesome fuel supply system :yikes:.


Oh wait I'll need a bunch of fittings and braided line to go with it :haha::eek1:. Another few hundred bucks :doah:.


So this piece of the puzzle may take some time to aquire parts for, but I know what I need to buy at least.

Next step is to finally nail down why I still don't have torque convertor lockup. Last thing I think I can check is if I have a good ground going into the trans plug. I know I have power. But I have to confirm the ground circuit. If all that checks out, it's getting pulled to get a rebuild. I'd love to put either a 4L80 or NV4500 or ZF650 in, but that's just not in the budget. A decent rebuild on the 700 will do just fine for now.
 
Why not swap it to a blazer tank and an in tank delco 381? Lot less money, and more than enough fuel supply.

It's an early diesel that doesn't need 55-65 psi. A 381 is overkill by a factor of 20 for an old oil burner like what he has.
 
Ah. I skimmed past the motor pic and thought small block.
 
Even a stock intank pump and a blazer tank is cheaper than just those valves though.
 
Or external pump. Whichever works best for the dizzle
 
Yep, the db2 injection only needs between 8 and 12 psi of fuel. 55 would blown the seals out, lol.

My plan has kinda been to keep the passenger saddle tank and install a k5 tank (Would be the 25 gallon version). The driver tank spot would be used for either an air tank or batteries. Having the two tanks would still give a good fuel range.

Plus it would be kinda trick to have dual fillers on the same side of the truck.

I'm almost as bad as Paul (@ryoken) where I have a picture in my head of what I want. That doesn't mean it always makes sense to everyone else:screwy:
 
I was thinking the 31 gallon by it's self. And I meant with a regulator when I brought up the other pump lol. Seen the 15 psi part.
 
The sanity of anyone that keeps and mods a 6.2/6.5 has to be questioned.
So 1000 bucks for a fuel system for an obsolete diesel is right on track.

Will be a sweet setup for the duramax swap someday.
Carry on.

:thinking: I forgot they made a 31 for the k5s. I was thinking a 25 was my choice. I know there's no room for the 40 from a suburban. That's what's nice about the fass, it has a regulator built in.

Let's be serious, none of us spend money on these trucks because it's a smart decision. :D besides if I swap something else in you'd have nothing to gripe about :haha:.

I've considered a duramax swap. Decided I wanted to stay with a non-computer setup in this truck. Hence no 4L80 either. A 12 valve Cummins is never out of the question though. But for now, the 6.2 stays.

While I Normally agree. The price of new vehicles is so out of control these days its starting to make more and more sense in sticking money into the old stuff.
Basically it comes down to if you are willing to deal with the older vehicles and their "character" and are willing to go with out all the gizmos, gadgets, and gidgets of a new vehicle.

Personally I am.

The 31 gallon spectra premium is GM14C.

If a stock gas intank pump works with diesel the old 350 tbi one is like 16 psi.

I looked into a new dodge diesel out of curiosity. Damn near 75 grand and it wasn't even fully loaded. Definitely keeping my two rigs around as long as I can. Course I really need this old running good as I have some fairly extensive work I need to do to my dodge.

@shady That tank would work just fine. 16 psi and then through a couple fuel filters might work. Do the tbi sending units have 3 ports or two? The diesel's use a 3 port one.

I like the plain old carter style pumps that they used to run on a Cummins. Like this one. https://www.napaonline.com/en/p/CFPB0238E?partTypeName=Fuel+Pump&keywordInput=carter+fuel+pump
How come you need three of those valves? Don't you just need one for feed lines and one for return lines? What am I missing.

I have a fass pump on my dodge. So I can run the same fuel filters on both trucks. It has a water separator and a 10 micron filter. Less part numbers to remember or buy if both trucks run the same setup.

The engine technically only needs two, supply and return. The tank has a 3rd which is the water in fuel drain. The fass has a full flow return which requires it's own return line. The flow would be too high for it to be merged with the return line from the engine. So I would need a valve for each line; supply, fass return and engine return.

I think I have brackets for a k5 tank somewhere in my stock pile. I'll have to dig them out. It's either still in Florida or up here in jersey with me :thinking::rotfl::dunno:

I can always add the saddle tank back in the system if I need/want to. Wouldn't be to hard to do once I have the better pump and such.
 
Well the k5 tank brackets are down in my old place in Florida. But it's not tragic as I'm thinking of making a trip down in early spring. Plus the truck is running on the one saddle tank right now. Which is the important part.

This weekend I'll do a final testing of everything that I can on the tc lockup. I'll finally know for sure if I have to have it rebuilt or not.
 
This is madness. $1200 for fuel fittings, not even counting the tank? :eek1:

What is wrong with using a stock double-pole fuel switch?

What is wrong with using the stock electric lift pump?

Hose routing aside, what problem are you having with your existing fuel setup? Replacing the whole fuel system is serious overkill if your problem was just a kinked line. :1zhelp:
