So I went & got another fuel pump installed, took for a test drive & the noise didn't occur. But then again these couple of days have being relatively cool (mid 20s) compared to before.
Also noob question:
When you guys talk about fuel cooler, is it just one of those generic oil coolers or are there specific coolers designed for cooling petrol?
Since I can't find any specific ones for petrol on Just Jap website, can only see oil, transmission & FMIC.
