As far as i know, most engines nowadays do not need any fuel pump. That's why i was pretty shocked when my hubs told me his father just bought a beck arnley mechanical fuel pump for his old truck which he uses it to deliver oil palm fruits. My FIL is actually at his ripe old age already but he is still working hard. Sometimes i just can't understand him, he should have enjoyed his life with his sons, daughters and grandchilden instead of working hard since he doesn't have financial problem. Em..maybe money is more important than family life.
