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

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
