Fuel Filter location

Any one have any comments about installing a fuel filter in between the fuel pump and carbies on a Type 3 ( or I guess any car). You hear the odd comment you shouldnt but apart from the filter bursting under pressure I cant think of any reason why not. John

That's not enough of a reason for you?

Do what you want but just get a fire extinguisher and know how to use it.

I have not seen a "filter" burst yet but I have seen the lines/hoses come off or break and start spewing fuel over the engine. You kinda want to keep "extra" connections to a minimum and your idea creates 2 additional possible leaks.

A lot of vehicles will place the filter between the carb and the pump! Of course a lot of them use metal filters too! ;-)

Where was the gas filter placed on the 1967 Type IIIs anyway? I have not worked on one in decades. :-)

And yes use precautions like ensuring that the ign cables and clamped fuel hoses are in excellent shape and a fire extinguisher is handy. ;-)

The bursting issue is not the worst of your worries, it's the added unsuspended weight of a filter full of fuel, flopping around in the engine bay, that is sending tugs and jerks up the hose and into the carb top fitting. The fuel fitting on the carb is just pressed in, it loosens up and eventually the pressure in the line makes it pop off. Meanwhile, the carb bowl still has enough gas in it to keep the engine running for a long time, and thus pumping fuel all over the engine compartment.

In the engine compartment, you have sparks flying in the generator/alternator and the distributor. It's a guaranteed, explosive fire: fuel, air, spark.

The fuel line separated on the '58. It was behind the engine, of course. Just a pain in the butt - better than a fire.

Aw, Jan, the thing can be covered in sealed-cell foam and tied down. It won't put weight on anything. I'll send a picture of my setup... when the fire department leaves.

Sometimes the engine just stops and does not burst into flames until you try to start it after the car has stopped and all air flow has stopped in the engine compartment. Pumping raw gas over the dist makes for a good ignition.

I've fabbed a stainless steel bracket for the filter before, but on the suction side. Just eliuminate the risk on the pressure side, and don't put a filter there. Simple enough. The pump has it's own filter built in anyway. There's room in the engine bay for an inline filter BEFORE the pump.

Perfection! :)

That is exactly what happened to my '67 when I first got it. It was dying as I rolled into the service station.

No fire. Knew how close it was burning down tho, obvious as anything with the whole -hot- engine compartment dripping with gasoline. Opening the hood could have sparked it off too.

BTW the new zolo-tone(?) paint job inside the engine lid, was never the same after that. ;)
