Is this a normal fuel pump setup?

[IIA]

I was poking around my 1970 IIA 88" today and saw something that seemed odd to me. Does this setup sound normal (or a good idea): Fuel line comes out of fuel tank (under passenger seat/LHD), runs to plastic fuel filter (I'm assuming it's a filter - still learning) on right of engine, then line goes to a small gray box that says Purolator (assuming it's an electric fuel pump), line comes out other side of pump and goes to another plastic fuel filter located between the oil filter and the engine block, line comes out the other side of the filter, then runs over the top of the engine and then to the carb.

That sounds different from what I've read elsewhere. Is this normal?

Normal for someone who was having issues with their mechanical filter and bypassed it.

The aparatus on the block is the mechanical fuel pump, it should have a glass bowel, and is a pump that creates a small amout of preasure to bring fuel to carb. at manifold. The purolator sounds like it could be another inline filter.

Forgot to mention, another reason I think the Purolator is an electric pump is the wire and inline fuse connected to it. In fact, I just googled "Purolator electric fuel pump" and found a photo: https://tinyurl.com/q9yxea5

I don't see a glass bowl anywhere. I've read-up and learned how the mechanical pump would be connected to the engine for power. I assume removing the pump would leave a hole in the engine. So does that mean the mechanical pump (or what's left of it) would still need to be down there somewhere (kind of like an appendix)?

I was most surprised by the 2 filters. One yes, but 2? Maybe the previous owner had a problem with dirty fuel?

Pictures make this a 2-post thread.

If the first plastic fuel filter looks like this and is attached to the engine block, it's the mechanical (engine-driven) fuel pump:

If it looks like this, it's an in-line fuel filter:

If the thing that says "Purolator" on it looks like this (or doesn't look like this but has wires coming from it), it's an electric fuel pump:

[EDIT:] Looks like I'm a slow typist--You already cracked the code on the fuel pump question.

Looks like the inline filter (but solid white, encrusted with dirt).

It's not typical, but the PO (Previous Owner) may have removed the mechanical pump and fit a blocking plate to cover the mounting hole. The stock pump location is at the very rear of the block, just below the head on the right side, if sitting in the driver's seat, of the engine
