Holley carbs on Motor Homes

I have a 1977 Ford E350 with a 460 4V Motor-craft carb. No one seems to have a kit or all I really need is an accelerator pump in mine, the carb works great just the pump does not work at all. Any suggestions on where I might find an accelerator pump for a 4V Motor-craft?
Or would a Holley carb be better for fuel mileage? I have many Holleys some original Holley Ford like a (E1UE-9510-RA) with a list number of 9874 which I can't find in a Holley book most likely because it is a Ford Original Carb it is off of a 1981 E350 with a 460. I know that carb on that van was not good on fuel at all!
Also have a Holley carb list number 7974 that is also a Ford application carb.

I am planning a trip in our Motor Home next week and would really like to get the best fuel mileage possible for this trip of about 5000 miles!!
Any tips on the best carb or any other tips on what well make my 460 get the best mileage possible?? The Motor Home has 53,000 miles on it.

Thank You in Advance for any help at all!!

Re: Holley carbs on Motor Homes

In my opinion if you have a motorcraft carb and holley carb of similar cfm and they are both setup and tuned correctly for your engine then I don't think there would be alot of difference as far as economy goes.

I would expect one of the parts stores should be able to supply a carby kit for a motorcraft carb. There must be still a number of them on vehicles out there.

If parts are unavailable then your only choice may be to pop a holley on it.
