I looked into that area for debris, there was none but I don't see how the screen filter would be very effective as it's not a tight fit in the chamber; maybe I don't understand how it works. Thanks for the compliment on the car. TomO 10-22-2011 @ 7:13 AM reply profile send p.m. Senior Posts: 7386 Joined: Oct 2009 Flatbob, the metal top of the fuel pump is a sediment bowl. Later pumps have a separate glass sediment bowl. I'm glad that you finally got your car running and all of the debris out of the tank and line. I really like the color of your car and you did a great job on the restoration.

Put everything back together and runs even better than before; I didn't think that was possible. By the way the carb was rebuilt by "Uncle Max" and never doubted it for a moment. Thanks everyone for the help. Bob supereal 10-21-2011 @ 12:06 PM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 It appears that the rebuilt carb is the problem. If the car ran good before the carb was swapped, but not after, that is the clue. The debris in the bowl is probably generated by removing and reinstalling the fuel line. Your filter likely caught most of it. I am always suspicious of "rebuilts". At our shop, we get many of those, together with faulty new parts, some of which are OEM from the dealer.It is likely that the carb should be sent back to the rebuilder, or looked at by someone familiar with it. Carbs are fairly complicated units, and one mistake in assembly can render it useless.

I have a metal inline filter just before the pump. Am hoping there is a way of solving this problem without dropping the tank. Am going to dismantle carb. and see if there is debris in the carb. TomO 10-21-2011 @ 8:14 AM reply profile send p.m. Senior Posts: 7386 Joined: Oct 2009 The debris in the picture should not keep your car from starting. It looks to big to get through the sediment bowl screen into the carburetor. The inline filter may be leaking vacuum at the connections. The Ford fuel pump is slightly higher than the fuel in the tank, so it must develop 10" of vacuum to fill the carburetor bowl. Tom supereal 10-20-2011 @ 2:43 PM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 We use name brand inline filters, such as Fram. They are available in plastic or metal. I prefer the metal type, particularly under the car. Just be sure to use the worm type clamps, rather than the spring kind furnished with the filter. If you are inserting the filter in a metal line, be sure to use hose barbs between the lines and the hose.

I have a screen type filter just before the pump but was told the glass see through filters aren't available any longer. 1932BB 10-20-2011 @ 6:59 AM reply profile send p.m. New Member Posts: 104 Joined: Oct 2009 Paper pleated types of fuel filters work best between the pump and carb as the fuel is pushed through the filter under some pressure. A screen type filter may help if mounted before the pump, some being transparent so inspection is quick and easy, as is cleaning. I use both with good results. Flatbob 10-19-2011 @ 6:27 PM reply profile send p.m. Member Posts: 437 Joined: Oct 2009 Thanks for responding guys, my inline filter is located just before the inlet port on the pump. I put the debris on a white paper towel and upon closer inspection all the particles are a shiny black material; any ideas what that might be? The fuel line is new and I blew it out when I installed the tank. Funny thing is my wife's MG TD stopped running the other day; I gas them up at the same high volume station with the same grade of fuel. I never thought to check for dirty fuel on her car but now I will.
