Not only are they now (mostly) fuel proof, old pumps commonly have worn arms and weak springs. Thankfully, mechanical fuel pumps are still widely available. The 59A-9350 pump with the glass bowl is about $60 from most vendors, and some NAPA stores still carry them. 37RAGTOPMAN 07-17-2011 @ 2:20 PM reply profile send p.m. Senior Posts: 1992 Joined: Oct 2009 if you want to keep it FORD, call THEN and NOW, CALL 781-335-8860 have all the numbers and makers name info of the pump you want to rebuild. to get correct kit, Tom is the owner,they also can rebuild your pump for you, I used one of their kits to rebuild my fuel pump years ago, just bought another one for just in case, when I drove to SARATOGA SPRINGS, but it was not needed, my 3 cents 37RAGTOPMAN This message was edited by 37RAGTOPMAN on 7-18-11 @ 5:16 PM TomO 07-18-2011 @ 8:13 AM reply profile send p.m. Senior Posts: 7386 Joined: Oct 2009 If you are rebuilding your pump every year, then either you have worn linkage, are not installing the diaphragm correctly, are not replacing the valves or you have debris affecting the valves in the pump. The diaphragm from Mac's and other suppliers should last for at least 15,000 miles. The diaphragm should be installed in the pump and the screws tighten until they contact the lock washers, then operate the pump arm several times and then let it relax while you tighten the screws alternately. I would like to know how you diagnosed a bad diaphragm. Usually when they go bad, they leak. Tom supereal 07-18-2011 @ 9:21 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 Besides affecting fuel delivery, a leaking pump diaphragm can allow gas to enter the oil pan, which will eventually cause bearing failure. It is often overlooked when checking the oil because it seems that the engine is just not using oil. Be sure to sniff the dipstick if the oil doesn't decline. Chances are you will smell gasoline. More than the diaphragm wears out in a fuel pump. 46fordnut 07-18-2011 @ 5:54 PM reply profile send p.m. Member Posts: 332 Joined: Oct 2009 ok here we go...i can only run the car off of what is in the carb. fuel pump barly fills up the glass bowl. to line off the carb no fuel comes out when i add to bowl and get engine to run. lines are clear no blockage no leaks at any lines . push rod moves as it should. the only thing i dont understand is when i get the rebuild kits it come with two cork gaskets . they look like they go into the glass bowl .. but the glass bowl only can take one at a time. even ran a different line to a gas can pump never took any fuel from it. there hens i think i have a fuel pump issue. p.s found leaking power valve and leaking main jet seals. using different carb that has no issues like the one that was on the car. do have light smell of gas in oil. 100 horse running wild This message was edited by 46fordnut on 7-18-11 @ 5:57 PM ford38v8 07-18-2011 @ 7:28 PM reply profile send p.m. Senior Posts: 2883 Joined: Oct 2009 The second cork is for the top cover of the pump. You'd better change your oil before you start the engine again. You're dangerous! Alan supereal 07-18-2011 @ 7:49 PM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 At the risk of repeating myself, I suspect your fuel line is nearly blocked with rust. Since the arrival of "oxygenated" fuel, the problem has become more common. A weak pump simply can't pull hard enough to keep the sediment bowl filled. A blocked line can produce fuel pressure, but not enough quantity to run the vehicle. 46fordnut 07-18-2011 @ 8:24 PM reply profile send p.m. Member Posts: 332 Joined: Oct 2009 im planing on change the oil and filter shortly and go over all else . she will be fine . i promise . i change oil at least once a year with the filter regardless how many mile i drove. unless i hit 3,000 thats different. the flathead wont die on my shift! my tank was cleaned just about 2 years ago.lines are newer put them in 2006. 100 horse running wild
