First bet is internal disintegration of fuel lines, some of which are post filter, but open them up too.

This car is just sooo good.  Thank you for bringing it!

 

The more you look at it, the nicer it gets.

It certainly seems like that could be it, but I replaced all the fuel lines just a few years ago. The only one I'm not 100% sure was replaced was the elbow at the feed from the fuel tank. It's a larger diameter so it's possible I didn't have the right line but I just can't remember.

Feed elbow usually presents a puddle first. Good filter should prevent that. Open the filter.

never opened a fuel filter before, so not sure how to read it but it seems like there a lot of junk in here.

That looks like the stuff that accumulates in my X1/9 tank when ever the car spends a few years sitting. I have not yet had it get through a filter. Is all the dust on the outside? If the crud is from both sides of the paper you need to back flush everything and it is your culprit. If the outlet side was clean you may have more trouble downstream.

The crud seems to all be on the outside, though there is a lot more than I was expecting. There's only like 20-30 hours of run time on this filter since new haha.

In reply to Robbie (Forum Supporter) :

I had to remove the tank and clean it twice in the time I ran my silver car. I had sat a decade at least when I first bought, and the striations in the tank looked like it was run 20 miles once per year. All washed into a container and evaporated into what you have in the filter. There is a soldered in fine brass mesh pre filter in the tank too.
