    1982 C30, idea for active triple tanks, not just a transfer tank.

    At least from what I found the Suburbans had either a 25 or a 31 around those years. We had a 2001 Silverado with the 8.1 and an Allison trans... great tow rig. Only sold it because we went from a travel trailer to a motorhome and wanted better MPG out of our truck. Our motorhome was a Ford...

    Appreciate that! Looks like exactly what I had in mind and don't have to start from scratch.

    1982 C30, idea for active triple tanks, not just a transfer tank.

    I'll take another look at the website and see if it's on there. I bought an 87 Suburban for parts so if that tank is good can probably use it. Right now only 1 tank works, guessing the valve is stuck and possibly partially blocked. Hope to get it on the lift this week and run a new line to the...

    1982 C30, idea for active triple tanks, not just a transfer tank.

    My truck has aftermarket travel tanks that run from just in front of the rear wheels to right under the front seat. Also, as mentioned, the tanks stick down below the rockers so much more exposed than stock saddle tanks.

    1982 C30, idea for active triple tanks, not just a transfer tank.

    In the process of getting parts and pieces together for the dually build. Picked up a 2003 8.1 with a 4L80 a couple months ago, on a stand in the shop for now. Anyway, have been working through ideas for a fuel system since the massive travel tanks won't work. Figure they might be reasonably...

    Anyone running an 8.1, what trans are you using?

    Just wanted to update on the fuel issue. Finally got some time and started pumping out the tanks. Ran a long hose off the electric pump output into a barrel. Right off noticed that fuel flow was terrible and the fuel looks bad... lot of crap in it. Color is more toward brown so think that's...

    Lowering 1981 c20

    I ended up buying a flip kit, said will get me about 7 to 8 but can use shackle extenders to get it back to 5 or 6. Not ideal but will see how low it actually ends up. In the middle of a house remodel and keeping the wife happy is more important than getting the truck done so the dually sits and...

    Possible to run EFI tanks without the internal pumps?

    Great! Actually bought a beater 2003 Suburban to use as a tow rig until I get the dually on the road. It'll be the engine donor.

    Possible to run EFI tanks without the internal pumps?

    Am going to be swapping my 1982 6.2 for an injected 8.1 but have run into all kinds of complications. Intended to continue to run the 6.2 until the 8.1 and trans were rebuilt and ready to drop in but the truck has these huge aftermarket tanks that are in bad shape, keep sucking up water and crap...

    Anyone running an 8.1, what trans are you using?

    Isn't there a high and low hump in these trucks? Just towed it home, another 3 mile trip and then it dies. Might be water in the tanks, drain and flush next job. Quick update. Had a few minutes between coats of paint so checked the filter trap... water and some crap in it. If anyone is...

    Anyone running an 8.1, what trans are you using?

    Did come across a 2wd trans out of a 2007 with 80k on it. If minor updates will keep it alive seems like a much easier and cheaper route to go.

    Anyone running an 8.1, what trans are you using?

    I like those valve covers. I'm getting lazy in my old age, like the automatic unless it's a just for fun car.

    Anyone running an 8.1, what trans are you using?

    Holdener has a few tests with the 8.1, the ZZ502 cam swap on a junkyard motor got 464 HP, 582 TQ. Most of what I read a stock 4L80e is good for around 440 TQ, 4L85e says 460 which is just over the 455 the 8.1 was rated at. I had a 2007.5 Dmax with the 6 speed Allison and it was great. Would...

    Anyone running an 8.1, what trans are you using?

    Am in the process of rounding up parts and pieces for my 1982 dually. For anyone running an 8.1 what trans are you using? Only plan a cam swap on my motor so not a serious build. Have a 2003 Suburban with the 8.1 so planning to swap that in. Unfortunately it's a 4x4 so can't use the 4L85e...
