Dual tank delete

[Frankenchevy]

Me personally, I have been trying to figure out a way to link the two tanks. Not to hijack the thread, but I really want to keep the two 16 gallon tanks, be able to fill up on either side with 32 gallons from dry, and only need to run the one fuel pump.

I haven't figured that one out though.

You can run a cheap electric fuel pump from your secondary tank into your primary tank’s filler neck vent with a ‘t’. Not the sending unit vent.

3/4” brass barbed pex fittings fit well for the filler vent tube iirc.

This method does require you to have a switch in your cab to activate the secondary inline pump. You can use the stock selector switch and/or location though.

You’d still have to fill the tanks individually. There isn’t enough capacity on a 3/8 supply line to keep up with a gas station pump.

The alternative is a blazer/burb single tank under the bed.

I have been trying to figure out a way to link the two tanks and be able to fill up on either side.

Back when these trucks were in production, there was a company that built a kit to fill both tanks at once. I don't know how well it worked, but basically it was a pipe that ran across the frame and had some type of "T" above the neck of each tank, then up to the filler neck.

You remember where the third filler neck went or did they figure out how to use the factory ones? The second would be interesting, as it seems fuel would need to go uphill somewhat.

My 77 originally had two 16 gallon tanks. While doing the 5.3 build/conversion I had considered a single 35 gallon blazer tank but went with a single 16 gallon tank on the drivers side, didn't want to mess with dual tanks. I have had the selector valve leave me stranded a couple of times. At this time i need to stop for a fill up every 3 to 4 days with daily driving to work (130ish miles). One day I may go back and install the 35 gallon tank and locate the filler behind the drivers side tail light. BTW, latest MPH was 15.2 for daily commute while running AC.

Curious, can y'all not mount a Blazer, or Suburban tank? I like my 42 gallon tank.

Oh yes but shes a thirsty bitch!

49 cents adds up fast with 42 gallons.

If it were me...
I’d wait for the dual bed.
16 gallons go fast

Other than the left side fuel fill hole, what is the difference between the two beds?

I'm thinking of removing a right side section of an old bed around the fill hole , and welding it into my current bed on the left side.

Comments???

The stock bed has so much rust not surface rust it’s not really worth restoring.

I would absolutely love to have a 42 gallon tank! I drive 100 miles a day, so with low MPG, a big tank is a must. That's why the 16 gallon tank is so annoying. I really wonder if I can mount the Suburban tank, I'll settle for the Blazer tank though haha

I have an LS it gets great mileage too.
But 16 gallons is still every three days.
I drive about 70 miles a day probably on average the old girl sees high revs and 80-90 MPH
And our gas prices are terrible in commicalifornia

@73c20jim
Also these beds unbolt.
Might there be a way to swap side panels?
Or is it too rusty on the entire sides?
As for me yaaas I’d weld them if It’s what I wanted/ needed
