Fuel Tank Relocation (and new Rear Bumper design)

Fuel Tank Relocation

For people reading this- I BELIEVE it's necessary to have an aftermarket bumper with the F150 aux tank. The way the stock bumper bolts to the body, the brackets protrude into the area the tank has to sit.
Its also more difficult in an '01/02(of course), as the EVAP shit is in the spare tire area-

Another hurdle- of many- is the tailpipe routing. I just did a turndown for[what] now, but the emission testing here requires a tailpipe to extend to- at least- rearward of the axle.

Found the one on Rockauto with "Fuel Pump and Tank Assembly Includes Fuel Tank; Fuel Pump Pre-Installed In Tank and Mounting Straps; Tank Assembly - Includes Tank; Sender Assembly and Straps"


1990 FORD F-150 5.8L 351cid V8 Fuel Tank & Pump Assembly | RockAuto

Debating on pulling the trigger....

is there a return on that tank? (carbs vs. fuel injection)

From the site is says Fuel System Compatibility: Carburetor Not sure how much difference there is between the EFI and Carb tanks. Care to infom me the differences?

I've thought about adding the f-150 tank more then a few times. My plan was to keep the factory tank and use it as an aux tank, greatly extending my range. I nixed that idea and went with Rotopax instead. lol

Now I'm wondering if you do the delete and replace it with the F-150 tank will you have passenger side lean? Lot'ts of us are running springs that compensate for drivers side lean by having a taller driver side spring. Take the weight and center it and you'll be leaning to the right. lol

My buddy has done quite a few F150 tanks in Toyotas, and he said there is a model that came with an EFI 351.
I wish I had more info on it, but that's really all I know. The tank I have is from a diesel, so it has no fuel pump. I just got it for mock-up, and plan on sourcing a used tank with the pump from an EFI rig. I could just get the drop-in pump/sender, but they are honestly more than I will have to spend to source the whole tank with the pump already in it.
Actually, I did do the F150 tank in my buddy's custom cab-

Depending on what springs you're running, probably. I would imagine it would lean if you have corrected the driver lean.
But honestly, this tank is a pretty custom swap, and requires quite a bit of various fabrication. Adding trim packers would be the easiest part of the swap, by a long shot I would say.

A fuel injection tank typically has the fuel pump in it whereas a Carb typically has a mechanical pump on the engine. A fuel injection pump pushes the fuel, usually somewhere from 45-65 PSI. A carb fuel pump is 4-7 PSI. A fuel injection tank will typically have a return line depending on the fuel injection setup. Carb engines typically do not. Hope this helps.

 

[AssBurns]

Hope this helps.

Definitely helps. Wasn't too sure what the differences were. Thanks!

Now to figure out if the one on the link I posted is actually for a Carb only model of if that is just the generic model and just has "carburetor" because it's generic. I might try to see if my brother can pick one up for me to see if it will work. Never messed with gas tanks before. How could I tell if it is made for carb or EFI just by looking at it?

The tank I used on the CC above has a feed and return line on the top of the drop-in pump unit. It's 2RZ swapped, so it's a FI engine.
I believe the carb model would just be a feed line, and a sender unit. Both tanks will have a vent, but don't confuse that with the feed or return lines. The vent is in the center of the top of the tank.

 

[AssBurns]

I'm going to see if my brother can order one for me to check. If it's wrong, I'll just return it.

F-150s had EFI 351W as an option from 88-95 but even the 302W trucks had the rear tank. 88-95 should be the years to look for EFI as that is when all Ford trucks went to fuel injection.

In the linked thread, the author cites the 91-96 tank (but uses a 95, IIRC) - is the 88-95 year range more accurate for our purposes?

I'm trying to determine the difference between these two tanks:

Spectra F1G

Spectra F1E

any idea?

The only difference I see is capacity. No idea how that relates to any real differences on our end.

I saw a thread somewhere (Pirate4x4 maybe?) that talks about there being a couple different sizes. 18G, 19G and 38G.

 

[jkeith.w]

OK, I just pulled the trigger on the F1G on Amazon for $76 shipped. I didn't get the sender and stuff - not sure which way to go on that just yet. (would like to see those blocked Photobucket pics first!)

 

[AssBurns]

Awesome! I was thinking the same thing. I'll pm the OP of that thread to see if he is willing to fix the photos.

Not sure if there was any difference in tanks, I just knew that 88 was the first year that all the F-150s became fuel injected. Although I misspoke about 95, 96 was the last year of the square body style for the F-150s. I'm excited to see this progress as it is on my to do list seeing as how I have a JB Welded gas tank right now.

The race is on, boys [emoji1619]

photobucket censorship aside; any thoughts on how to go about mounting the tank? clearly there are straps on the underside, but topside crossmembers take up overhead space and lower the tank.. any thoughts on a flange mount solution?

ah - just noticed the upper strap depressions in the tank - so not so height-restrictive as I assumed...

I smell a mount kit in the werks...
