86 b2 tank swap into 98 ranger

[swickwake]

i ran into some problems with my swap. i ben doing a lot of research and talked with a few people about this swap. everything i found and heard said that when it comes to the electrical and plumbing of the thnk is straight forward and is pretty close to plug and play. i found that this is not the case when it comes to my swap. i pulled a tank from a 86 b2 that has a 2.9 fuel injected v6. i got the tank mounted and re-positioned my charcoal canister. this is where i hit a brick wall. the diameter of the sender/pump on the B2 tank is smaller then the my sender/pump on my oem tank. im not to happy but im going to enjoy figuring out this problem.

so my question is where do i go from here. i have some ideas but i would like to here some others.

does not hang to low

You can't just plumb in-line reducers?

I think he means his 98 pump doesn't fit through the hole in the tank.


90 went to a 1-pump system. Should give you the pressure you need and fit the tank. The other option is to get a pump replacement kit (not a sender assembly) for a 4.0 and put it on the 86 sender unit.

Can sombody fill me in on this? Like why you would want to run a b2 tank in a ranger?
is it for the duel tank set up? or is it to reposition the weight of the truck and counter the lean issue?

Then he will still have the problem with the senders resistance not matching the fuel gauge. They changed around 88-89.

Ah. lol ADSM, pulling through with the common sense and knowledge, yet again.

I'm unfamiliar with the resistance values between the BII years and motor choices.

People do this swap for difference reasons. Some people do it to run dual tanks, change weight distribution, or increase ground clearance, but most people on here do it to fit a doubler setup.

(This isn't meant to sound condescending, but some 2WD people haven't heard of a doubler.) They mate two transfer cases together (usually a BW1354 or 1350 combinations), for increased gear reduction in rock crawling situations. This makes the overall x-case length longer, necessitating the shorter gas tank or a rear mount BII fuel tank.

In addition to what Pete said, the B2 had the largest single-tank capacity of any RBV. The twin-tank Rangers had more, but the system is much more complex and you only gain about 2 gallons of capacity going that route.

Then he will still have the problem with the senders resistance not matching the fuel gauge. They changed around 88-89.

True. I think it was 89 that the resistance changed, since 89 is when the dash and instrument cluster changed. But you can pick up a fuel level sender, for about $25, but I'd go the whole 89/90 sender route.

im doing this for the weight distribution but mainly i want to design a cantilever shock set up to be forward of the axle.

this is what my pump/sender looks like. plus the diameter of the mounting plate is about 1.5" larger.

notice the sender in this pic. the mounting plate is smaller.

with all the material that i have found said this will be a simple swap.

Put an '89 BII pump/ sender assembly in and call it a day.

 

[swickwake]

i do not see how that will work. if my sender/pump did not have that black thing i would.

an idea that i have is that i will use the b2 sender, ranger pump, and drill a hole in the top of the b2 tank for the black sensor on the ranger sender. from there i will match wire and hop my truck does not go boom.

 

[Sasquatch_Ryda]

Thats a fuel tank pressure sensor. You could possibly drill a hole in the top of the tank and remount it?

theres a 23 gallon ranger tank...the huge loooong and fat bastard plastic one with the plastic spinny cap to hold the sender...i think i had one from a 95 or something...due to my powertrain and old style frame bridging at the time i had it bed mounted for a bit. also i had two what i thought were 26 gallon huge fat bastard explorer tanks from 4 doors for extended range in my psd on the floor.
maybe i remember those wrong...i did physical vol checks on them with water though...maybe i remember it wrong.

i would trim down the newer unit or fit that shit to the b2 unit....or make a custom piece. generally i make a custom one with 10 gauge so you can make it stout as you can.

its a couple hour pia detour at worst.

this is what i came up with to solve the issue i had. the swap was not as plug and play like as i had hopped. the main reason it did not go as smooth is because i was dropping a (OBDI) 89 bronco 2 tank in to a (OBDII) 98 ranger frame.

this is what your sender should look like

this is what my sender looked like.

this is what i had to do to make it work for me. (I do not recommend anybody doing this)

98 ranger sender cut up

hole cut in to tank to match the plate cut from the sender

plate from send tiged into the b2 tank. the blank sensor measures the in tank pressure and the little white thing use to have the wires that powered the pump go through it. is just a plug now. im using the connector on the 89 b2 sender power the pump.
