here is a pic of the Fuel pump rod, nothing wrong with it, the car ran fine when i just hook up a house straight from the fuel pump, when i connect the hard line from the tank, the fuel filter goes empty after i crank the car and it is idling, i really do not have the money to do all the new stuff right now, i am trying to get this motor back running so i can sell it, and then i plan on replacing everything, i don't understand why when i hook up the hard line from the tank and put a hose from a gas can attached to the hard line bypassing my tank and sending unit, the fuel filter goes empty, i have checked the complete hard line and there are no leaks, it almost acts as though the fuel pump just stops working when i hook this line up?

the pump/rod/line to carb/filter are good and the prob is rearward from the pump. That only leaves the hard line rearward (including the 2 neoprene connector hoses) OR the pickup assy. did you hook the jar to the neoprene connector hose at the tank? This'll tell you if it's the hard line/2 neoprene hoses OR the pickup assy.

the hard line is the original, the car has been undercoated and the fuel line looks okay from the outside, so to save some money right now, can i buy a roll of that cheap alum. fuel line and run me a new line for now, so i can get the car back running to get the 440sold and then i am going back with my new 440 i just bought this week, so my question is, can i run a temp line for now to get the car running ? upon further investigation , the gas tank has had some repairs and i really need to replace, so my plan is , get the car back running, sell the current 440 and i will do all the upgrades, new tank, 3/8 stainless line, new 3/8 sending unit, i really just need the car running to get the motor gone

What have i been saying, the hard line obvisously is the problem, or that short rubber hose that goes between the cross-frame by the trans crossmember, your running in circles, if your getting fuel from the pump too the carb, but once you try & run through the hardline is gets restrictive .
You have ruled out the Tank/pick-up/rod/pump, this sounds like a re-pete to me, i told you to yank out all that hardline & replace it, either with a role of 3/8 aluminum line from summit/jegs, The aluminum is very easy to bend & its cheap too, just use your old line as a template, OR a factory line, but there not cheap.
The mech. fuel pump will not have a problem sucking fuel from a long distance through curves/bends IF theres NO restrictions or air. . Its not "ROCKET SIENCE"
If theres "air" it would be dripping fuel on the ground.

I'm sure you will have problems finding "aluminum" line locally, i know i couldn't, the only other bet is "copper" at Home Depot or Lowe's, its a bit pricey & hard to bend for tight corners around the frame rail, the aluminum is the easiest & not as likely to kink. Once the hard lines been re-placed (along with the short rubber hose at the crossmember) & by ANY chance its still having issues, it'll make it alot easier to narrow it down. When i disconnect my hard line from the pump, it'll poor gas instintly & drain the tank, Oh but i'm running a fuel cell . Let us know how it works out!! http://www.jegs.com/i/Moroso/710/65330/10002/-1http://www.jegs.com/i/JEGS/555/15100/10002/-1

Joe, thanks for the link to Jegs, i went on line and ordered, the new line was at my door step by the 3rd day, i went with the Moroso, cheap however very stong. can you believe that i got put it in without a break, 1 line from fuel pump to the tank, i have to admit it took the better part of the whole day yesterday fighting with the shocks and exhaust. thanks

Glad you got it fixed, but i will tell you a buddy of mine ran mid 11s in his BB A body for 8 yrs. with the factory 5/16 line, BUT he ran a helper Elec. pump, I'm still convinced the factory line had issues somewhere because that gas NOW looks crystal clear .
