Dual Tank Ranger Problems
This problem has been driving me nuts for a year now and I don't want to just start throwing parts at it. I know it is something simple but I am lost.
It has intermittent power to the fuel pumps. It doesn't seem to matter which tank it is on when the pumps quit. I have run a hot wire from the fuse box to the back of the dual tank switch in the dash. I have to move the hot wire from one side of the switch to the other depending on which tank I am using. This works fine for me but I am afraid one of the kids will flip the switch without disconnecting the hot wire. DEAD SHORT & flame on. Without the hot wire sometimes it will run for a few minutes but mostly not at all. Any ideas where I should start looking? 1987 Ranger 4x4 auto extended cab V6.
Thanks
PS: Any one know where I can find a replacement rear tank for this.

Looks like you're not getting voltage to the dash switch on pink/light green.
OOPS, my bad make that pink/black NOT pink/light green
Voltage from the inertia switch is spliced to the frame mount pump & to the dash switch.
To hold the pump relay closed while you look for the missing voltage see this link.

Good luck with it.

Pop the hood & the pump relay is under a plastic cover on the passenger side fender.
At the relay & with the key on, you should see voltage on solid red & tan/light green (from the main relay)
you should see voltage on solid yellow (from a fuse link & hot all the time)
As mentioned at the link I gave you when you ground tan/light green the relay should close & put voltage on orange/light blue.
Next stop is the inertia switch (if you still had one) & then the frame mount pump & dash switch.

I have a 84 dual tank Ranger, but it is carbed not EFI so my switching set-up is different. As for rear tanks, hit the salvage yards................Saw 2 of them in the same yard here.

Thanks for the info. But I live on a remote island and there is no salvage yards. Believe me I have looked and I haven't found another dual tank Ranger of any vintage. It's one of the reasons I picked up this truck. I haven't pulled the rear tank yet to see if it is salvageable. And I can't see it with the skid plate in the way. Being in this salt air and the rust we have here makes me think it would not be cost affective to try and repair it hehehe. I would be willing to pay to have someone pull a good one and ship it to me$$$$$

Thanks for the tip Rangerman. I bought it. From what I can see around the skid plate in my truck I think it will work fine.
87XLT do not look at the junk yard. I got one coming.
