It is the power for the cross over valve pug it back in to the bullet plug on the switch over valve and that should cure your problem the switching valve changes over the tank sender as well as which tank to pull from. Defauts to driver side if it loses power.

SOURCE: i have a gas leak at the tank. When I fill to full, gas leaks out

you might try looking to see if the filler tube is cracked and leaking if it is you could replace it and that will take care of the check engine lite depending on what code is being set

Fuel levels are equaled in the tanks via a frame mounted transfer pump that transfers fuel from the rear tank to the front tank where the main pump is. Your transfer pump needs replaced, and should run about 60 bucks. Should find the pump mounted to the frame between tanks.

SOURCE: Leaking Gas on left side of gas tank, can't tell if it's the line

More than likely you have a busted fuel line, or one of the connections from the fuel lines to the fuel pump is broken. If you know how to repair cars, drop the tank and find the leak. If you don't know how, have the vehicle towed to a shop. Driving the car would definitely be a fire hazard.

I have a 1986 Ford F-250 with duel tanks and I don't recall what the capacity is or how many gals will each tank hold ?

Most of the standard Ford and Chevy tanks the 1980-1990 for pickups was 20 gals with long necked fills - so you could fit 21 gallons per side.

How can I check for a fuel leak in the passager side tank? And how many gallon's of gas dose eack tank hold? 1986 GMC K1500 4X4

Each tank hold about 17gal. For the leak, first a thorough visual inspection. If no leak is found remove the plastic shield. And give it one more good lookin over. If STILL no leak is found, you can purchase a UV dye additive that will highlight the point of puncture under a UV light.

My son ran my truck out of gas. Its a 1988 F250

first, is this a diesel? if it is there is a line or oring loose allowing it to **** air--diesels dont like leaks like that and there is a whole procedure for voiding the air from the lines on diesels. next could be the in tank pump and also does it have duel tanks? does the duel tank switch work? running out of fuel with in tank pumps can burn up the pump (the fuel itself provides lubrication and cooling for the pump, gas or diesel) and of course check the filter, running out and refilling could have disturbed trash in the tank
