Hey all,

I have an 84 D150 that i am looking to change the fuel system in. I currently have the stock fuel tank, but with lowering the truck it seems dangerously low since it hangs well below the frame rail. Also, it needs a new pickup anyway.

So it seems like a good time to change to a fuel tank that sits between the frame rails.

I have heard of people swapping to an early style Mustang fuel tank. This sounds great in theory, but i have not seen a lot of people who have actually done it.

So... people who have swapped to Mustang tanks...can you please share photos/ install suggestions? What did you do for a fill? I can fab mounting brackets, etc.

Thanks!
Tim

not my pics. some do the filler in the bed floor, some do behing the license plate.

If he's lowered his truck, the Mustang tank looks like it sits lower than a stock frame mounted tank

Pinto anyone.

Nah, it's very little different than Ramchargers or vans. Add a trailer hitch for extra protection if you're concerned about it Pinto ing...

The tank you show is sitting a lot higher and has a shield arround it.

Why does everyone insist on lowering these trucks???

Getting too old to climb up into them?

The current trend is to lower the trucks, the old trend was to lift up the trucks.

I prefer to have the seat about butt height when I open the door. My wife is a little shorter then I am, the truck has running boards for her. When the seat is at chest height when the door is open, its just about as bad as having the seat at knee level when the door is open. I don't want to have to climb up to get in, and climb down to get out, any better then I want to bend way down to get in and then have to figure out a way to climb up to get out. The truck is suppose to work for me, not me work for a ride in it.

The new stuff is way too high, in my opinion.

When I removed the in-cab tank from my '71, I replaced it with a late-70's C-body tank. It fit perfectly between the rails in the spare-tire area, with the filler behind the plate. I don't remember the size, but it was about double the in-cab, and I'm sure it would be significantly bigger than that Mustang tank.

lowered trucks look like crap.

Okay, good to know. I'll swap it back for you.

i was trying to remember that when this topic was posted, and you remembered it for me ! thank you sir !
if i remember correctly, [there's that "remember" thing again ] the 74-78 C-bodies i owned over my lifetime were somewhere around 22-26ish gallon tanks ?
mustang tanks are maybe 15ish [?] and in cab truck tanks are maybe 14ish ?
just an old guy who knew many things years ago, but has forgotten lots due to the spiders hiding the knowledge in his noggin with cobwebs...............

I'll join in with the questionable memory thing, I put one of those 25 gallon C body tanks in an old Dodge pickup. I think I had to move the frame crossmember between the rear axle and the rear crossmember forward for that tank to fit. The moved crossmember was very close to the rear end. I also remember the fill tube (with a new gas cap) behind the plate would dump fuel if the tank was 3/4 or more full on hard acceleration, with the perspective of a 360 727, 3:23 gear drive train. That truck sat low, but the bottom of the tank was above the bottom of the rear bumper.

apperciate it

I agree and would never lower one but to each his own.

Just because no one else is saying it, I kind of like them lowered a bit. Not dragging on the ground lower, but a few inches down looks petty good if the do the complete job and not just hack it and leave it unfinished.

Lower earlier trucks, pre 73 or so almost always look better to me, but that may be because I do a lot of frame swaps and those tend to lower older trucks.
May I present two versions of the basically same truck, one raised, one lowered. Both are/were mine. Pic 1 is a 50 Dodge on a full size 80 Dodge 4x4 frame. Pic 2 is a 49 Dodge on a Dakota 4x4 frame.

Second one has a much better looking stance.

Thank you,
I like it better too.
The tires on both trucks are the same size, 235 75R 5, and the tires on both trucks are mounted on 7" wide wheels. The 1st truck was about 12" too high to go under my 7' high garage door, the 2nd truck fits under that door just fine.

In their original application, Mustang tanks were the trunk floor. The pinchweld sat on the frame rails and crossmembers. One could do similar to the bed floor.

Another option is Ford truck tanks, move your existing filler neck from in front of the wheel to behind. Up until the mid 90s the sending units were compatible with the Dodge gauges. Depending on year, an electric fuel pump is easy to add.

If you have 4WD it goes up, If you have 2WD it goes down. What i don't understand is why anyone would want to lower a 4WD but i still see questions about doing it.
