Good evening,
I am having a few problems that I hope someone may have solutions for.!) I own a 1977 Ford Holiday Rambler Imperial 5000 the V>I>N> on the title is short for any search for information from it.

This is a project/home. It had been sitting for 10 years as a project from the previous owner, ( started 20 projects finished none ) it came with a box of "stuff" that may or may not belong. Now to my first problem: i needed to purchase a fuel pump, it was towed to it's present location, the replacement from the information I gave them '77 Ford [460 cdi ] was way off the arm was almost straight compaired to the originals curve upwards.

Both the markings Carter- hi flo 0-02440 and the sticker D5UE-AC has resulted in no matches. Has anyone found a solution to these issues, I am so wanting to be traveling and enjoying the places and people I meet.

Thank You, Terry Knighton

There's no engineering reason you need to replace the in-tank fuel pump with another in-tank. Just get and install an external pump. They are everywhere and are economical. Relatively. Napa has them, Autozone, Rock Auto, etc. I got mine at Napa.

Thing most needed would be for all the fuel lines to be replaced. Then install the external fuel pump. It gets tricky if there's rust in the tank or if the in-tank fuel pump has crumbled (not likely) as the external pump needs to pull fuel out through that old pump. Usually it's just install and go, so that's the good new. Might put a fuel sump before the external pump to capture all the goo and gunk and debris that's likely to be in that old tank.

Of course you'd probably want to drop that tank and scrub it out professionally if you can. Costly but saves lots of trouble down the road. That's the time to change all those rotten fuel hoses on top of the tank too.

Anyway, here's a source of external fuel pumps. Thousand of these are used in race cars all over the world every year...Summit Racing Fuel Pumps.

They have generic in-tank pumps too. All you need know is the equivalent car model that uses that engine. That was the hard part when I was spec'ing my external pump...matching up the PSI of fuel needed by the engine with the output of the pump. Turned out it was only hard in my mind. It's pretty straight forward after reading a bit about fuel pumps vs engine size.

A '77 460 engine will have a front timing cover mounted fuel pump. Carter seems to have changed some of their pump designations for whatever reason as it cost me many hours to find the one I wanted one for a simple Ford 302. I ended up with a marine version of what I had.

Take a look here - you don't need a Carter fuel pump:https://www.summitracing.com/search/...r=fuel%20pumps

JEG's is another source of parts for these engines as well as Rock Auto Parts

Then if all else fails, you can always go with an in-line electric pump but that will take a fair amount of plumbing and wiring plus a relay to accomplish since it needs to mount near the tank

I have seen that too. For some reason the old 460 pumps either have an actuar arm that is bent like a dog's hind leg or is almost straight. I have noted the ones parts stores seem to have on hand are the straight style. You need someone a little older and smarter than me to be able tell you is they are interchangeable or what the deal is. They sure don't LOOK like they interchange.
The one time I ran into this was years back at NAPA and they grubbed up another dogleg style one out of the back somewhere so I didn't need to experiment.

(Ignore al that "in tank pump" stuff. It does NOT apply to your older coach.)

Been too long since I've 'fooled' around with a 460 but have owned at least 2 F350s and 2 cars with them and have had them down to bare blocks but way long ago

I had the same problem on a '76 460 a few years ago. An old school parts counter person pushed the computer aside and got out some parts books.
After about an hour of phone calls he located the correct part.
