914-6 w/2.4 '72 911 "T" motor, MFI
The previous owner of my car (let's call him "Bubba") installed a regular plastic in-line fuel filter between the tank and the fuel pump. The factory fuel filter is upstream (between fuel pump and injector pump). Is this "pre-filter" necessary? Looks like one big fuel leak waiting to happen. (IMG:style_emoticons/default/blink.gif) |

Iv'e never seen anything like that before.
What motor? what year? Why would there be a second pump for the fuel inj's.? do they run at an extreemly high pressure? Are you sure that's not an air inj. pump for smog? |

Are you sure that's not an air inj. pump for smog? Motor is a 1972 2.4 "T" motor from a 911 (see first post). The fuel injection pump sends fuel to the injectors upwards of 200psi. I am 100% certain that is not a smog pump. It is the injector pump. |
