any one know how many gal. per hour of gas a stock fuel pump moves?

Have you checked at auto zone stores? Which engine do you have and which motor mounts? The side dog bone mounts on the sv8 engine needs the #6959 pump. The pump body must be 3" long from the mounting surface to the mid of the round area.
 
Is the body length the 3 inch long pump? There are 3 different body length fuel pumps for the sv8 IH engines that I have found. I have 2 3/8", 2 1/2" and the 3" body length. All three pumps look similar and all have the same part number - 6959. Only the 3" body length pump will work with the side 'dog bone mounts'. Measure the body length from the mounting surface to the 'middle' of the round knob at the end of the pump.
 
Here is a round about fuel flow requirement answer to your initial question...

Stoichiometric brake specific fuel consumption (bsfc) I = to .45pounds of fuel/ hp/hour. A one hp engine making its rated 1 hp and running for one hour will consume .45 pounds of fuel. This is linear and consistent for any properly tunes gasoline engine at any hp range....
a Scout making 200 hp will burn just below 15 gallons/hour assuming you use 6.2 lb/gallon for fuel...

Double that for flow losses and 30 gallons/hour will be fine..
 
Holy cripes, at 60 mph that's 4 mpg. However come to think of it, I've gotten as low as 8 mpg towing an rv trailer, so I guess that's within reason.
 
Mathman Robert is reel close.

For 266 through 345 engines; the book shows that at 4000 rpm the pump is rated at 27 gal/hr @ 4.5-5.7 psi. We'll probably never use it's full capability, but there it is.
 
Bsfc is a fact not a myth.
If you are cruzing down the road I doubt you are using the rated power. 8 mpg @ 60 mph is 7.5 gph or 103 hp average.
Those be the nutz about that....
 
Awesome info answered my question
by the. Way pump is good driver. In timing chain is bad
putting off repair till I need to get into that area wont introduce me to future problems will it?
Seen yotas do this alot

:icon_eh:

not quite sure where that came from.
I know from studying for a coast guard license for engineer on motor vessels it's a fact of life. Vessel owners also want to know propulsion costs and you ain't got mile markers at sea.

I had no doubt that you understood. You actually posted while I was pecking away.

I fixed the random punctuation, so the post would be a little easier to decipher. IH engines don't have timing chains. The mechanical fuel pumps are driven by a special lobe that attaches to the camshaft in front of the cam drive gear. To access it, you remove the belts, pulleys and front timing cover. I don't think delaying this repair would hurt anything aside from driveability.
