Spitfire Spitfire Fuel line filters

Hey Guys,

Can I ask how many fuel line filters should my 73 spitfire have?

It currently has 3 filters and I am thinking that seems like a lot.

I have one at the gas tank, then one before the fuel pump by the frame and then one after the fuel pump before the carb (this one they have mounted on the engine block at the top, not sure if that is a good place for a plastic filter)

Any information would be great.
 
You sure it's a Spitfire and not a Red 69 TR6 :whistle:
 
I think on a '73 the factory filter is the one next to the tank in the boot. (That's where it was on my '72). It is not uncommon to place a second filter after the pump and before the carb(s).
 
Thanks everyone. So I can eliminate one of them. I will keep the one between the fuel tank and the fuel pump and then from the fuel pump to the carb just for safe measures.

Doug can you tell me where the filter between the fuel pump and the carb is mounted? Right now they have it mounted right above my exhaust manifold about 1/2" from the engine block an to me that doesnt seem very safe for a plastic filter??

As I mentioned earlier, it is common to place a filter between the pump and carb(s). However, that would not have been "from the factory". It is just common practice to keep debris out of the float valves and bowls.

The filter I have installed is a translucent (air cooled VW type) disposable plastic filter. I have the SU conversion on my car and the filter is in the fuel line immediately before the carb. That does place it above the manifold but not close to it. My car came to me without any carb heat shields so I have a high-temp foil blanket covering the header, sandwiched behind the intake manifold. It's still a hot area but not as hot as it once was.
