fuel pump fuse melting, not blowing

I have read the many threads about fuel pumps, clogged fuel pipes, relays, iffy fuseboxes, etc, but haven't quite found the answer I am looking for.

DX engine, both fuel pumps replaced, fuel pump relay replaced a while back. Done the test by using relay 18 instead, and all OK. Checked current draw at the fusebox with engine cranking and running, the pumps are pulling 6.9 - 7.2 Amps, so well within the expected 5-8 Amp range. But, the fuse (no 5) is getting hot enough to melt the plastic on the blade fuse. No sign of heat damage on the fusebox or under the relay. There must be some resistance somewhere to cause the heating, if the current draw is normal - is my fusebox on the way out?

any advice gratefully received

yeah sounds liek the fusebox, mine did the same thanks to water damage

Cheers John for confirming - oh goody  

May not be too bad of a job, (altough as a MK1 newbie I've not yet had occasion to go near my fusebox I speak from experience on other cars) it may just be high resistance at the particular fuse, try getting a very thin emery board and cleaning the relevant pair of contacts in the fusebox, worth a try and will only take a few minutes….

I have the same fault LeeO with my mk1 golf gti just ordered new fuel pump and relay .. Just changed the relay , with the new relay I can't hear the relay click or the fuel pump prime but starts up in 1st click ….

Did you get any joy with your

Hi, have been away, so not much progress since. I did try emery cloth, but couldn't force between the fuse contacts - I will see what else I can find that might do the job.

can't do any testing for a few days, as my rocker cover is now soaking in degreaser to try and clear the breather mesh!

Thanks for the suggestions
