So im trying to get a toyota running right now, and I think I have it narrowed down to the fuel sending unit not building enough pressure due to a leak. being that the tank is just ratchet strapped onto the "bed" of the truck im probably going to end up ordering a spectra tank and sending unit to replace it since the current sending unit is rusted into the tank and they both could use replacing. (tank: and the fuel sending unit: incase anyone has input about those?)

Im am brand new to toyotas and know about nothing about them and working on this is being good learning experience for me, but I dont have any manuals to go off of. I was wondering if any of you would be able to identify what each of these (http://imgur.com/a/csjUD) lines going into the current fuel tank are for so I can label them and hook them up to the correct connections on the new sending unit when it gets here?

Thanks a ton in advance for any help.

What year, model and motor?
The pics from amazon show the tank and sender for a GM vehicle
You already have a pic as to where the hoses go.
IDK, if I'm missing something here.
Maybe someone will chime in and set me straight

Well looking at the pic the very front one that appears to be part of the tank is the vent line that runs to the charcoal canister. The rear most line is the supply line, runs up to the fuel filter. and the return should come from the fuel pressure reg.

I said the rear one was the supply line but after looking at the pic again I guess its not really the back line more like the one on the left side

From what I read he is asking about the 2 fuel hoses that fit on the "Sender"

Sorry, now realizing that this was not super clear. To make refrencing the hoses easier, lets call them A B and C is labeled here: http://imgur.com/a/r74zA

Hose A would be the return right? I think. I do not know what hoses B and C go to.

This (https://imgur.com/a/XtexU) is the vehicle the tank is on. The tank is literally held on by ratchet straps to the back, and the tank on it now has a leak and the fuel sending unit likes to spit gas out of the top and needed to be replaced, and is fused to the tank. So I ordered the tank and sending unit I linked on amazon since with the setup being a tank ratchet strapped to the bed, I'm not really worried about vehicle fitment, more of just need a box that doesnt leak and can have a pump plopped in with power ran to it.

Planning on ripping the current tank off, mounting the new tank, running power/ground to the new fuel pump and hooking it up to the switch that controls the current one. Just want to be able to label the hoses for where they would attach to on the new sending unit before I pop them off since I dont really know what they go to and cant pull the current sending unit out to check.

On a side note, the wiring to the starter on this truck is shot, so if I were to snip the cable running to the starter at the connector that plugs into the starter (mainly to just get the connector without ordering a new one), and spliced a new wire onto that and ran it to battery positive and a momentary switch, that would give me a push button start more or less right? Key in the ignition still being turned to keep it running, but just seems faster to bypass the original wiring harness with a push button for the starter than it would be to start tracing wires.

Thanks for the help!

Maybe this will help, "googled image".

A is the vent from the charcoal canister, C should be supply line and B is the return from fuel pump, if its a 22r, or from the fuel pressure regulator if its a 22RE

ksti

Yes, looks like your good to go now.

thanks for the help, to make sure before I start cutting wires, I am correct in the bit about the starter wire I mentioned above right?
