It's time to get fixing the gas guage on my 1977 Chevy C10 so we'll know when low fuel starvation occurs. Did we remove the box or did we remove the gas tank? Find out right now on this episode of Olde Carr Guy.

Good stuff, you got the fuel gauge working. I noticed those jack stand hangers right at the top of this episode. Great idea.

[@OldeCarrGuy]

They are such a good idea, I bought 2 more! lol

[@RoyMarkosGarageRMG]

How did I miss this one? I blame the notifications on KZbin. But I’m here, and “things aren’t always easy.” Wise words.

[@OldeCarrGuy]

No worries man! Thanks for continuing to watch my stuff.

[@NicksGarage]

"Things are never that easy" Ain't that the truth!

[@OldeCarrGuy]

100% truth! Thanks George.

[@NVSRides]

Great to see you out cruising the truck.

[@OldeCarrGuy]

Thanks 👍It's great to be out in it again!

[@tomc6177]

My back was hurting just watching you!!

[@OldeCarrGuy]

LOL Not so much my back, but contorting my arm in ways it isn't supposed to.

[@NotaMechanicJack]

Gotta love c10s!

[@OldeCarrGuy]

Love hate some days

[@Str8sixfan]

As long as you don't call it the petrol station...glad you Canadians still call it a gas station. 2100 at 80mph is pretty impressive! We've been having some crazy wind here lately too.

[@OldeCarrGuy]

No petrol here sir!

[@shadetreejoe3986]

14.4 Isn't horrible given a windy day and the aerodynamics of a brick. When I put the 454 in the wife's 1978 C-10 nearly 3 decades ago, we didn't have an OD transmission or EFI. I ended up swapping the 3.73 rear end for a 3.08 geared unit, and put a heavy secondary spring on the Holley 3310. Cruising at 70 MPH, 12 MPG was a solid number, corrected for the tire size and gear change. If you're cruising at 1800 RPM, those numbers should come up as things settle in.

[@OldeCarrGuy]

I did another run yesterday with no wind and got the mpg's up to 15.5. I thing once I fine tune the EFI I should be able to get an economy tune saved for travel. But I do see 3.23's or 3.55's in my future as well.

[@shadetreejoe3986]

@@OldeCarrGuy unless you plan on a lot of towing, I think the 3.23 rear gear with the 700R4 will make for a happy combination and net the best fuel economy you can hope for. We've had diesel trucks with 3.55 gears, 32" tall tires and a 0.72:1 overdrive that got great fuel economy, but the diesel had the torque to pull all those numbers.

[@HFG]

Awesome!!

[@OldeCarrGuy]

Thanks bud!

[@lifelover2301]

I am curious if you use the Imperial gallon or the US gallon when calculating your MPGs ? I really enjoy your videos and keep up the great work !!

[@OldeCarrGuy]

I generally try to explain it both ways but 14.4 in this instance was the Canadian gallon.

[@Reaglesracing44_]

where is the key buzzer located at? my 75 suburban don’t seem to have one

[@OldeCarrGuy]

Should be attached to the fuse box I believe. I'll double check on mine!

[@hermyherm365]

I’m curious what the mpg’s are ... much love buddy TMR floor jack holders interesting!

[@OldeCarrGuy]

I'll have a better test once i get this thing dialed in!

[@georgecerda7802]

I'm curious as to why you didn't just get a tank for a 1987 EFI truck? You can then get the sender/fuel pump hanger that mounts in the usual location and a bucket in the bottom of the tank to help with fuel slosh.

[@OldeCarrGuy]

Simple answer is the efi system was a sponsorship frim Fitech and they don't offer a direct replacement for the factory sending unit. That's why i went with the new tank an reused my original gas guage and installed a new pump. Thanks for watching.

[@pieterloock8911]

Just a quick question, do you have the original steering column and seat in there? You seem to have a lot of room between yourself and the steering wheel?

[@OldeCarrGuy]

Hi Pieter. The steering wheel and column is stock, but the seat is out of a 88-98 GM work truck. I did a video on the seat conversion. kzbin.info/www/bejne/rofXhIWOoK-fetk

[@patlubin9197]

@4:00 so full is not at the F tick, but at the beginning of the arc? Is empty touching the left arc?

[@OldeCarrGuy]

Pretty darn close! I don’t let the needle go past the E!

[@patlubin9197]

@@OldeCarrGuy Cool, thanks. We have the same gauge and it didn't occur to me until recently that I might not be getting a faulty reading. I am going to fill a gas can and try to run it empty past E.

You just wont get good gas mileage on a 77 chevy truck. 14 or so is pretty good for what your driving. If you want better mpg, put a 250 cid inline six cylinder engine in it.

Hey what happened to Duff?🤣

None of this would ever have happened if Duff was in charge!
