Thanks all for your help! I bought a second hand EZL today for R 300 (+-$37). I tested it at the spare parts place and it worked wonderfully! Now I just need to get some of that heat sink paste and I'll install it tomorrow.

Oh, and my original Fuel Pump Relay works with it!

Thanks again,
Jase

P.S. I managed to get some 'Heat Transfer Silicone' from the electronic engineers where I work...plus point of working at an electronics manufacturer... ;-)
