#1 fuel filter and fuel line

Post by Walluski » Sun Dec 01, 2019 9:42 pm

Howdy,

Regarding my 72 S3 2+2:
I need a little reassurance that this is really how this is supposed to look.
After pulling everything out of the boot, I noticed that the flexible hose to the fuel pump, with the inline fuel filter, simply hangs from the front wall of the boot to the pump? It actually rests on the spare unless I push it away. Is this correct? Seems like an invitation to fail but I don't know if my car is setup incorrectly or I am missing something.

Thanks in advance for your help!
Mark

Thanks Ross.
I'll stand down and worry about something else.

Ross you have that aftermarket inline filter on the inlet side of the fuel pump - I would be concerned that you could get vapour lock with the high temps you get in summer up in Qld with the pump trying to suck fuel through that.

The correct filter on the outlet side that you have should suffice as the gauze filter on the pickup in the tank should be enough to protect the fuel pump from contaminants and the OEM filter in the glass bowl is good enough to protect the carbs.

Just an observation for consideration.

Thanks Garry,
That photo was taken just after the fuel tank had been cleaned. Lots of muck had been removed & a lot deposited in the fuel pump. It was just a precaution. The car had been stored for some time. When the tank was refurbished, I didn't find a gauze filter on the pickup in the tank. The filter may have been removed by the previous owner. No problems with vapour lock though.

Wow - that is not good - I can understand you putting that filter in - my point still remains valid though but I would leave that filter in place until you were happy the crud was no longer coming through. If then car stops on a hot day you know it will be either vapour lock or that filter getting clogged up. I assume you have cleaned that tank out.

My comment about a coarse gauge mesh filter was an assumption on my part - I assumed there is one (not checked my own) as every other car I have has one in the tank pickup - including my 50s landrovers - though you have some fine sediment there and the coarse in tank filter will not stop that.

You must have been getting a bit of sediment in the main glass bowl filter.

For the OP - while your system is not as original, the fact that your filter might bounce around a bit, with the spare etc all in place all will be good.

I've checked the parts manual & I can't see a gauze filter. I will move the filter to the output of the pump once the car is on the road.

The brass gauze filter goes in at the top of the glass bowl above the paper filter.

Personally I would always fit an additional cheapo inline filter in the fuel line as the E Type tanks are usually full of crap.

Andrew
What are your thoughts regarding my setup of the el cheapo paper filter between the tank and the inlet to the pump? Should I put a filter at the front of the car prior to the carbs?

My opinion is just that; opinion, so take it as such.

I like to have a plastic inline filter between the tank and the fuel pump. I don't want big chunks of rust in the pump.

I inspect then regularly and change them if they look to have much crap in them. They're about $5 from Repco. Nothing ought to get past them so I'd be happy with things as they are in your car.

All my cars are S1 cars and I do have the glass filter/paper element in the engine bay but they never seem to get much in them as anything should get caught by the inline filter. Also, SUs have a mesh filter in the entrance to the fuel bowl. I'm not sure what the arrangement is on S3 cars.

Of my cars one has an original tank that I've never had out, one has an original that I cleaned out with hydrochloric acid and pebbles and one has a new tank. I don't seem to get much rubbish now.

My first car, my red 1.5, had the entire sump full of crap when I removed it and I ended up fitting a much bigger boat fuel filter in it, but that car has been sold now.
