To follow up on this thread, I appreciate everyone's suggestions. Ultimately, I decided to just refurb the stock tank and run it. It's the cheapest route and of all of these trucks I've owned over the years, having the tank there was never an issue with me.

Look for a tech post next week from me on gas tank restoration. I've done a few over the years that turned out extremely nice. I'm just waiting for a couple of things to be delivered next week before I do the post.

check out these folks- they advertise custom ohm matching & sender rebuilding.

Man, you MAY have just saved me a LOT (more) searching with this link.

My truck isn't a 60-66 but the issue I have an issue that maybe applies to some of you guys: My '46 truck came with some kind of F*rd tank between the frame rails and behind the rearend and it fits pretty good. Problem? It has the F*rd ring type sending unit retainer instead of the typical GM/Universal 5 hole type fuel sender mounting.

I had the truck pro rewired when I bought it last summer and I bought TPI-Tech gauges. I because I knew I wanted the original factory cluster restored (in the future) but it was too costly then. So I went with the lower buck TPI gauges. They all work fine - no issues, and they even look pretty good in my opinion, see here: http://www.tpigauges.com/prod03.htm

I just haven't figured out how to make their five hole sending unit mount in my type of tank? I've searched Summit, Jegs, North Hollywood Speedometer, and other places for an adapter or something and no luck. MAYBE this place has or will make something for this application?

Have any of you guys figiured out how to solve this problem on the cheap? I think the gauges are 240/30 ohm. ANY help would be appreciated. - Dan

without having seen your parts i think the answer would be to transfer the 5 hole sender assy over to a lock ring type. go to junk yard & get a sender assy that fits your tank. then remove everything on it except maybe the suction tube if equipped. then transfer the sender from the five hole unit over to the lock ring one. all it is being used for is to hold the sender in place so it should just be simple mechanics. be sure to install the lock ring unit in the tank before you transfer the sender so you can see how it fits & index the sender float in the proper position. i spose it should sit sideways to the tank so you dont get "slosh readings". i did this a long time ago on a military jeep that we put a civy fuel tank in. hope this helps!

All these threads talk mainly about 63-72 trucks.
I've seen the underbed kits for 55-59 and 63-72.
BUT I have a 1961 Apache C10 longbed. (Width/fit is different I'm assuming?)
What are my options?
Does anyone know of someone who has done this maybe a build out there?
Thanks dudes,

[ruffrida2005]

Are you going to do it like they did on Trucks one day, where they used a cleaner, then some kind of black liquid to fill the metal on the inside?

[andyh1956]

about six months ago i had to replace the gas tank in son n laws 69 mustang. i also had to rebuild the flange area of the trunk, because as most of you know the tank is the trunk floor & the tank sets on the flanges in the tank well. the tank comes with holes for the fasteners already in the flanges. it looks like with trimming the frame rails back then the tank could "slide" into the frame rails & then nut & bolt to rail. that way you wouldn't need the retaining straps. with a little rubber insulation under the flange & a rear filler this looks like the best setup to me. wadda yall think?

One other person on here has done that, he also moved the fill to one side..

Hate to revive an old thread but, Sir, could you elaborate on this install, please? I've seen Falcons in the salvage I go to, but it didn't occur to me to check out the tanks.

Thanks

I've restored some hopeless antique motorcycle gas tanks and have developed a real good set of techniques for them. I actually started on the tank today.



Step 1 is to clean it thorougly on the outside with a strong mixture of muriatic acid and water and a scotchbrite.

Step 2 is to pour muriatic acid into the tank and slosh it every which way repeatedly to get all of the nooks and crannies clean

Step 3 is flush with running water for a couple of hours to dilute and flush the acid out

Step 4 is cook in the oven for several hours at 300 degrees to get it thoroughly dried out

Step 5 is POR15 tank sealer. This stuff works like no tomorrow. It will even seal small leaks

Step 6 is powdercoat the outside for beauty

Currently, mine is cooking in the oven stage. I have the POR15 ordered and am waiting delivery. After that I will shoot some powdercoat on it and cook it again and reassemble with new sending unit and gaskets. More pictures to come as I get the stuff and get it finished.

POR 15 is da bomb! Used it on my vintage motorcycle tank a few years back and it still looks brand new.

[Tx Firefighter]

Sicboy, I actually know you from Triumph forum boards. I've got a Bonneville myself.

[toms84ss]

So what kind of oven does it take to cook one of these?

[Tx Firefighter]

I've got a big powdercoating oven in my shop.

Does anyone have pics of the Summit Fuel Cell installed?? I am at the point where I need to choose and budget is definitely an issue. :-(

[irish1966]

And I mean from the rear of the truck. lol. I'm considering it in my 66 long bed fleetside.

[markeb01]

Here's an earlier thread where forum member TheDark1 shows his installation of a Summit cell. May or may not be the same model you are considering:

[irish1966]

Thx Markeb01. It appears to be different. I will keep searching the forums. I don't mind the filling thru the bed so I think I will go with the summit kit. This is my first build so I'm learning as I go.

Rear tank with a receiver hitch? I know I read "something" about it on here.

I'm (99.9%) buying a trailer this weekend, and will need to ad some type of hitch.

I hope to move my tank, for more legroom in the cab.

[TR65]

Astro,

My underbed tank did not interfere with my receiver hitch but I guess it would depend on the tank. I used on from Rick's Hot Rod Shop.

If the 6x-66's are anything like the 67-72's, removing the tank won't gain you any additional leg room. The top of the seat hits the rear cab wall (under the back window) @ the same time the lower portion of the seat hits the tank. I suppose adjustable (forward tilting) seating would allow the seat to be positioned farther back @ the expense of a more upright seating position.

I have a '89 seat. My original was replaced with junk buckets, when I got the truck.
