Howdy: I have a problem that has gotten progressively worse, to the point that as of this afternoon the car won't start. I'm 99% convinced it's a fuel pump issue.
<span style="text-decoration: underline">Hardware:</span> '62 BT-7 Tri-Carb. Relatively new sealed aluminum gas tank w/ race-style flip-up gas cap. Metal fuel lines except under the rear seat/fuel pump area where the prior owner connected the metal lines to 1/4" rubber fuel lines (in which I have inserted a universal fuel filter). I have an SU solid state fuel pump, about 3 years old.
<span style="text-decoration: underline">History:</span> The car has been running really well at all speeds as recently as the day before yesterday. But over the last month I've noticed progressively more fuel pump ticking. It's always ticked a bit, but it seems like since the engine rebuild (3 months ago) it's gotten faster. It's now ticking constant and fast. Almost like a rattlesnake rattle??
<span style="text-decoration: underline">Repairs:</span> I assumed an air leak, so I replaced all the rubber lines and the fuel filter (in which there was minor but noticeable foreign material) and snugged the clamps tight. No improvement. I then inspected the fuel pump body and noticed no cracks in the housing. Also tightened the ground wire; it wasn't loose but it wasn't tight either. I then tightened the brass in/out pump fittings, and pulled one off and replaced the teflon tape. No improvement, and fwiw that's when the car would no longer start. I know the next drill: detach the fuel pump>carb line and see if it's pumping out gas, but any ideas what could be causing the cavitation/ticking? Sorry for the length of this, but it seems faster to be complete than respond to queries about things I've already done. Ideas?
Many thanks,
-Tom
