[Spits] Intermittent miss turns out to be fuel tank debris

[Roger Elliott]

I have never used a tank sealer kit, but of the people I have heard talk 
about them seem to be of the opinion that they work fine for a couple of 
years, then they start flaking off.

I don't suppose the leak could be coming from around the sending unit 
gasket?
