How to protect fuel pump wiring?
I had to install a new fuel pump in a ford ranger.
the connector in his truck didn't match the new fuel pump so I had to cut the 2 wires leading to the pump (inside the gas tank) and solder on the new fuel pump connector, then i covered it with marine grade heat shrink.
is this adequate at all? Will it prevent any explosion?
is heat shrink adequate to protect soldered wires from gaoline inside the tank?
DO NOT attempt to operate that vehicle. You were DEAD WRONG to cut the wiring inside the tank. Even given the likely FALSE assumption that a proper adapter is not available, you should have modified the wiring OUTSIDE of the tank. It is physically impossible for there not to be ample room between the tank and the power supply for proper rewiring.
I wouldn't worry about it at all so long as the wiring connections are solid and there will be no sparking due to a bad connection.
But even if there was sparking due to a bad connection chances are slim that anything would happen. You can drop a lit cigarette into the gas tank and nothing would happen because all of the oxygen has been displaced by gas fumes. Of the millions and millions of cars and trucks on the road for many many years, when was the last time you heard of a car exploding due to sparking in the gas tank?
What - are you going to be the first? Lol.
I think it would be okay. You can if you want double heat shrink it if you have a larger size tube.Adjust the wire lenghths so that the joints are not adajcent.
Car is low voltage just for that reason.
IT will NOT blow up the vapor in the tank is too rich and will NOT ignite even if it did spark AND anyone who thinks so can try if they wish won't succeed. Believe it or not but fuel pump motors have brushes. You had the right idea of using the heat shrink tubing just not sure if it will survive fuel vapors. Even if it did fail the most that would happen is a failure. Marc-poc is correct
You did it the right way by soldering the wires, I hope you staggered the splices so they can't short if the heat-shrink dissolves in gasoline. I have not seen marine grade shrink tubing, I would test a piece in gasoline to make sure it doesn't dissolve and get soggy soft while submerged in gasoline. Make a test splice and soak it in gas to find out.
Fuel tank repair epoxy putty would have been a better choice on the splice, allowed to harden before installing in tank.
- Location of 1998 Ford Taurus fuel pump. Does it have a fuel cut-off switch? Car shut down suddenyl without warning. New battery and cranks but will not start. Suspect bad fuel filter, 130K miles and fuel filter has never been replaced.
- What should I do to stop the rust and protect the bed of my truck? The bed of my truck (1990 Ford Ranger) is starting to rust. The rest of the paint and body is in good condition. I want to stop the rust. Should I get a bed liner like Line-X or should I just get it sanded and re-painted or is there some other alternative
- My 1999 ford ranger has 20 lbs of pressure on the fuel line. Do i need a fuel pump? After I tested the pressure and shut the motor off the pressure went down to 0 quick. When I just turn the key I don't get any pressure
- On my 2000 ford mustang why does my air pump (smog pump) only blow air for 5 seconds after start up? Is that normal? I have p0411 secondary air injection system insufficient flow detected. I've checked the hose that comes out from the pump, it's blowing air but I believe it should blow air for much longer than 5 seconds on start up.
