So after cleaning it a couple of times and still getting debris big enough to block up the 3/8” fuel line completely. I pulled it took to my radiator repair shop and was told that someone had tried to pour a liner into it and did a really crappy shop. It was breaking down and that’s what keeps clogging the line. Only one guy local does total rebuilding of gas tanks, cutting them open, sandblasting, welding, new liner and he was a bit backed up and at around $400 for it. So the owner (wife) wanted a new tank, purchased from NPD which is out of Ocala and with us being in Orlando it a day UPS ship. Their tank was a more then some others but free shipping with an order over $300. So tank, hard lines and a couple other items and boom over the free shipping mark easy.

Tank arrived yesterday late (UPS is always late in the day), prepped and painted it last night for an install today. Tank was a good heavy gauge steel which seemed to be like the original. This morning taking a good look and only the center mount hole lined up the other 4 top holes had to be drilled and the bottom did not have the flange on each side to mount it in place. Drilled the top holes, replaced all the mounting bolts and hardware due to PO taking needle nose pliers trying to hold the bolts in place to tighten. Used a bit of scrape aluminum to make a mounting plate for the bottom corners to hold the tank in place.

Then found out the fuel line fitting on the tank was 5/16” not the factory 3/8” which led me to 3 auto parts stops to find a flare adapter. So an install that should have taken 2 – 2 1/2 hours took 6 hours with running around. But new tank, lines, filter and rebuilt carb and it is running fantastic.

 

Congrats on the success!

 

Nice! looks great.

 

Nice work. Thanks for all the details on the NPD gas tank.

 

This is the supplier.

 

Oval Industries is Blue Oval Truck Parts.

D0TZ-9002-A (replaced C1TZ-9002-K) .. In-Cab Fuel Tank / Reproduced.

1961/66 F100/800; 1963/69 N500/750; 1967/72 F100/750.

 

I Ordered my tank from LMC says 19gals. and came with the adaptor fitting for the 3/8" fitting.

Orich
That. I converted to a efi return line.

 

yea, this one is suppose to be 19.5 gal. Would of been sweet if it came with the adapter fitting.

 

I'm thinking of using a 1969 used in cab tank in my 1970 f250. It only have the three mounting holes and doesn't have the mounting holes at the bottom. Sound and looks like the repro you purchased. Do you have any pictures of how you added the aluminum in order to mount/seat the bottom of the tank?

 

1970 uses a different tank than 1961-1969, but for some reason the parts houses (looking at you Dennis Carpenter!) want to lump 70 with the earlier years. I think it’s because there is a 71-72 only tank (for emissions trucks), but not all 71-72 trucks use that tank. The correct tank for 70 was used 70-72 (non emissions 71-72 trucks), has FIVE mounting holes up top, a flange at each end of the bottom with a mounting hole in each, and a 3/8 fuel fitting.

To make matters worse, Dennis Carpenter lists the 61-69 tank with the correct part number for the 70-72 (non emissions) part number. They do NOT have the correct tank.

Rock Auto has a FDGT-06 tank that looks to be a universal (at least I’d the pictures are accurate) as it has holes for both the 61-69 AND 70-72 mounting points. I’m not sure what the fuel connector size is. They are HIGH on shipping ($160 to my zip). I see that same tank on eBay for about $300 shipped. Good chance this is the same tank LMC sells (they are on back order from LMC).

 

I don’t have the cash for a new tank. I think I’m going to try and modify this 1969 tank to fit in my truck the way the OP did with their new one. Just need a better idea of how to do the bottom flanges.

 

@dedward ive got a 1971 behind the seat tank that i am trying to get rid of and i even put an ad on clist but we bumpsiders are a rare breed. you are welcomed to have it, i live in fresno but come down to LA to visit my kids and grandkids, not sure it will help meet your needs as i didnt read this thread too closely (i am allegedly working from home and right now in a mtg) its in good shape, worked fine before i started this project. i put a mustang tank between the frame rails and it was pretty simple so i am a big advocate for that move. the tank kit cost 150 shipped and the carter 4070 fp cost 50 which also fit nicely in the frame rail, just fyi

 

That would be great! I think the 71 bolts right on from what I’ve read. Yup, I’m in Los Angeles area. I’ll send you a private message with my info.

 

That’s awesome that it sounds like you have a line on a good used tank that won’t take modification to work. I paid $25 for a used tank from a 72 for my 70. It was a bit dirty, but rust and crud free.

 

This is what I did on the bottom corners, just a washer as a spacer and bolt it up.
