Also check your gas cap, to make SURE IT IS VENTED, ALSO use a gas tank from a outboard motor, with just gas in it,not mixed with oil, plumb this up ,directly to the FUEL pump, next to the car on a stool about the level of the fuel tank in the car,, if the pump works, you have a problem in the line or in the tank in the car, you have to rule out the problems, one by one, hope this helps 37 RAGTOPMAN

The filter that I use is clear, but it is not glass.

I have had good results checking the fuel pump and lines on a fresh start up by leaving the nuts off the fuel pump stand with everything hooked up from the tank to the pump. Then by looking at the pump and turning the engine over by hand until the pump is at the top of the cycle I then manually push the pump down several times until I have fuel comming out the pump discharge line into a container. This tests the system. Works for me.

Good point. The glass body filters must be mounted carefully and may be risky in the engine compartment, but if mounted well near the tank, maybe OK. Is my theory correct on the problems of using the paper pleated type before the fuel pump? Are there other types of screen type filters that are available?

I avoid the glass tube type filters like the plague. If the glass happens to bump against metal it will break and you have an instant car fire. I know of two old cars that had car fires because of these filters. Also because of vibration they can unscrew and leak gas.

I have had trouble with the paper pleated type gas filters when installed before the fuel pump. They don't seem to work without significant pressure. Try a screen type before the fuel pump. A popular one looks like a glass tube and has a remeoveable and cleanable screen.

Vince, because of the vulnerability of the fuel pump's valving, a fuel filter is best installed before rather than after the pump. For your rewire job, be sure that all connectors are soldered rather than just crimped, and that bullets and terminus points are protected with dialectric grease, available everywhere. I thought all V8ers started out sniffing their Dad's exhaust pipes. what gives with your peculiar allergy?

Alan Ben busy digging out of this mess we got all week every day--Ordered a new fuel pump..Now I'm into re-wireing everything--Now lets see what problems I run into on this stage of the re-build--Thanks for the in-put on the fuel problem--Also added a filter between the pump and the Carb-Haven"t been able to run it much, because of the confined space Im working in.. Carbon Monoxide and me dont get along to well.. Again Thanks Vince

Vince, Glad you got it running! You've isolated the problem, but with the spacer, you've fixed the symptom rather than the problem. Those spacers have been around forever, and are a temporary solution only. The operating pushrod doesn't wear, but the fuel pump rocker arm does wear at the pivot point. This is where you've lost the pump action, in the slop at the pivot. You'll need to rebuild your pump with a new rocker arm.

Alan-I blew air thru the line,back to the tank-When i sucked on the line(with my mouth)didn't know any other way--Fuel flowed out-Then I hooked up the fuel pump and worked it manually by hand-Fuel flowed out-Then when I hooked it to the motor,nothing happened-Then I removed the pump and added a spacer into the arm that pumps the diafram and reinstalled it and gas flowed out-Hooked it up to the carb , and the engine started running-I think the rod that controls the pump was worn-the spacer seemed to move the rod up and down further-Now i am rebuiding the carb because the chock fins are not opening-But the car is running--feel better all ready--thanks for the in-put, i did everything you said-and its running-Vince
