High Volume Fuel Pump?

[Anonymous]

Does anyone make a high volume mechanical pump for these engines? I'm still having trouble keeping my sons maverick running. It runs great, UNTIL it quits. It always eventually restarts and may or may not run great almost indefinately. I've been through everything on it. Ignition module, distributer, Coil, Standard Fuel pump, cleaned all the fuel lines, removed and cleaned the tank,etc. The 250 is stock with H/W 5200 and 6-1 header. The clear fuel filter sometimes fills up and sometimes doesn't. This is strange and very frustrating. Could the float be hanging up in it intermittently? It seems to run out of gas, but I'm not sure aboutn that, it just feels that way.

I dunno, but a fuel pump from another application can be modified to fit, it involves changing the lever arm on the new pump to the one for the 200. Not too involved from what I hear, but I've never done it.

I found a crack in the ruber line on the tank side of the fuel pumpon my 72 maverick. I belive it was alowing the pump to suck air part of the time. The car would run for awhile then quit. The clear fuel filter would never fill up, would fill part way only. After replacing that short piece of ruber line the fuel filter fills completely and the car does not quit. I never saw the car drip any gasoline with the bad hose on it so it must have only leaked air wheb the pump would try to draw gas from the tank.

Good Luck

An inline fuel pressure regulator and gauge would be one thing to consider. It'll let you know if the pressure's dropping, or too high/low - better than speculating.

A standard pump in working order, should be able to support that carb no problem. To interchange pumps, you need to be sure that the distance from pivot to the "hook" which engages with the pump diaphragm is equal on each unit. Australian cars with the 250 and power steering/aircon used a pump that pushed more fuel. I don't know if the diaphragm was broader or the arm longer.

yes its possible , i already did do it , high volume holley from a V 8 to a 6 inline feul pump .
just changing the levels ,thats it .

what donor arm did you use? I have my factory pump for my 170 that has a arm that goes UNDER the cam and the later pumps go OVER the cam. i am looking to make this swap in a couple weeks I think

i did use the donor arm from the old holley feul pump from the 200ci engine , wil take some pic of the model and post them here later .

 

[XFlow_Fairlane]

so were you able to find out what pump you used to get the arm from? or at least a pic of it?

can anyone Id that pump? doesn't look like either of mine

my old 170 pump was a bolt together job (has six bolts between the two halves and a single screw on a lower bowl on it)

my current pump 1978 fairmont pump is the non servicable pump with the two "towers" for inlet and outlet.

the old 170 pump went under the cam (well kinda like along the side of it) and the 1978 pump goes over the cam. so I am wondering if maybe a stock sbc or sbf pump could just be used?

ok I think I am going to be off to the speed shop again next week with camera in tow. I stopped in today and looked at holley (2 kinds) edelbrock, and carter pumps. seems there are 2 types of lever arms. the ones with a through pin and the ones with the staked in place pin. I am scared of using a staked in place pin because it seems like it would just puke out hte front unless I JB welded it all together or something.
