Hi

 

I am trying to remove the fuel from my tank and have made a relay jumper that goes between points 87 - 30 of the relay socket.

 

The Bentley book says to place a 15 Amp fuse in the jumper cable however that fuse blows when the jumper is inserted into the relay points. I see that the Dempsey 101 projects (fuel pump) has no such fuse.  Should I be using a fused or unfused jumper ?

 

Cheers

If it is blowing a 15 amp fuse, leaving the fuse out is courting disaster!  You have something wrong,, you should not be blowing the fuse.

Thanks that is what I thought however the fuel fuse (position C4) is a 30 amp fuse so I am wondering if my relay jumper fuse should be 30 amps instead of 15 . Maybe the fuel pump when it intially tries to start is drawing enough current to blow the 15 amp jumper fuse ?

Thanks Loren. According to the Bentley manual the fused rating was 25 amps up until 2000. It then changed for 2001 - 2005 models to 30 amps. 

 

So I guess I assume that the relay jumper doesnt need to be fused ?

 

Cheers
