It's a 25 amp fuse.

Maybe I can unhook the pump and see if it still blows the fuse?

I am wondering how the pump could've gone dry, though. I installed it exactly where most people do, on the cross member very close to the tank.

Make double sure the pos and neg ring terminals are not touching each other. Or tthat the pos is not ouching the frame or other metal.

Could be a weak or improperly wired relay. Is the relay on a socket or just spade terminal?

Anything else on the circuit?

Ok. I'm positive (no pun intended) that the terminals are correct and not touching anything they aren't supposed to.

I'm not sure about the relays. I've never messed with them. There are only two. Pretty sure they are the socket type.

It's doubtful that it's the relay, but it's easy to check. Disconnect the power wire to the pump and use a test light between the power wire and ground. This will tell you if the short is in the relay or (not likely) the positive wire between the relay and the pump. If the light comes on and the fuse doesn't blow the relay is fine and the pump is where the short is.

How do you know that the pump went dry? This is the first time you mentioned that it went dry.

Fixed!


Me, being the idiot I am, didn't secure the wiring as tightly as I should.

The fuel pump wire sagged and touched the muffler, melting it.

Easy fix, but I feel stupid.

The pump never went dry, it was just brought up as a possibility.

Thanks all for the help!!!

Live and learn I guess.


I've come a long ways since I bought this thing.

But I have a whole lot more to go
