Fellas, I hope somebody can help me out here.

I have a 1970 F-250 with the 360 V-8. I bought this truck off EBay from its second or third owner, so the details of its history are lost to me. I've been doing a significant reconditioning of the old beast to get it back healty again.

So I've come to the fuel pump. I ordered one from RockAuto, who I've had excellent results from in the past. Their database of car parts is awesome, and has been accurate thus far. I ordered a genuine AC-Delco part, but it does not match the one I removed from my truck.

So the question is, does my truck have an incorrect fuel pump on it now? It is a Carter, which leads me to believe it is after-market. The model number on it is Carter 0-1932, which I didn't see listed as offered for my truck.

There are two significant differences between the one on my truck now and the new one. The shape of the mechanical arm is different, and the new one has two threaded connections, whereas the old one has one threaded connection and one hose-nozzle connection.

I have posted a photo of the two pumps here:

Please take a look, let me know what you guys think. If the RockAuto database is correct, then good, I'll install this pump, work out the connections, and be all set. But if not, I'll need to return this pump and let RockAuto know of the discrepancy.

Thanks very much for any help!


Oh, one last side note. On the AC-Delco description page for this pump (part #717), the photo shows the bent mechanical arm, like my old one. This is suspicious.

 

Shoot, I forgot this last bit:

On the RockAuto database, the fuel pump listed for the 390 cid engine actually looks more like mine in the picture. It has the nozzle connector for the incoming fuel hose, and also has a bent arm.

Could the old man who owned the truck before me have mixed them up at some point?

I wish I could find him... there are so many little odd things. The carb had two hoses plugged up with golf tees!! (probably not original!)

OK, thanks.

 

Well, per the picture, the one of the left(dirty one) is the correct model for an FE. The one on the right(new one) is maybe a small block version, maybe? I know they almost bolt up the same, but the arm is what makes the difference.

I wonder if someone boxed it wrong, or someone picked the wrong part?

Once I specifically ordered bonded (non-rivited) brake shoes for my truck. I got riveted shoes. I went to the shop and and told them I got the wrong part. He looked it up and said, no that part number on the box is the right part number, that's how they come. So I told him to get me a set of the riveted, he comes back with a box that has bonded brake shoes in them, and suddenly he wasn't so sure...

Looks like the wrong part to me!

 

Thanks for the replies guys. That's an awesome story about the brake shoes!

So yesterday I called the AC-Delco "Technical Advice" people. It was about as much help as if I had called my own shoe. I was surprised that the guy had no way to look up a reference between the part number listed for my truck, and the numbers actually stamped on the pump I got. (to make sure the right part was put in that box)

What I've done now is ordered the pump for the 390 c.i. engine. In its picture on ACD's website, it has the nozzle hose connection like mine does, and also a bent arm. We'll see how my luck is with that.

I'll post a follow-up in case anybody else runs into something like this. Thanks again!

 

Advance Auto wanted 22 bucks for a fuel pump on my small block. I told him to look up one for a 76 with a 302, because I knew it didnt have the filter canister. I slapped it on there and got 2 of the clear filters from walmart. I saved 8 dollars!

 

Yeah, a small block pump will work in an FE, but it wpn't pump as mauch as it shoul. But put an FE pump in a small black, and the eccentric will be damaged.

Yeah, the old pump on the left is the correct one for an FE.

 

Yeah, the pump on the left looks like the right one, its the same on i have on my truck 71 f100 360 v8 hope that helps alittle bit

 

Here is a follow-up for anyone else who might encounter this situation.

I returned the fuel pump (AC-DELCO #717) shown in my picture. I then ordered the fuel pump listed on the AC-DELCO website as being for the 390 V-8, Part #41206. It is the right one! It has the bent arm, and a nozzle connection for the incoming fuel, just like I need.

This is a mystery now. I know that my truck "originally" had the 360, but the thing is 34 years old and I've had it less than one year. So I now must find out if somebody actually swapped in a 390 at some point.

I am going to get the casting numbers and look them up or post again on this forum to find out. If I do have a 360, then AC-Delco's web database might need to be fixed, or the part I originally got must have been boxed or labeled wrong.

Anyway, I am very excited to have the pump now... I should have the truck running by Christmas!

Thanks for the help!

 

Jam: You might want to check out the FTE FE forum here for more good details about your motor.
The 390 is of the FE Family of engines. The most common FEs you will see are the 352 (used in trucks up to '67), the 360 and the 390, both used in trucks to '76.
The only difference between the 3 is the bore and stroke; all other things interchange. So, the fuel pump for a 360 will be the same for a 390.
If you can confirm the stroke, you can confirm if it is a 390 or a 360.
Here's the easy way to check the stroke without removing the head. Get a straight 12 inch piece of white electrical house wire or coat hanger wire. Get a magic marker. Remove the number 1 and number 8 spark plugs. Turn the engine over until the timing mark is at TDC. Put the wire in the number 1 spark plug hole with wire resting on the top of the piston. Make a mark on the wire even with the lip on the valve cover. Now move the wire over to the number 8 cylinder and mark the wire again, at the lip. Measure the distance between the two marks.

For those that don't know: 3.98 is the stroke for the 410 and 428 engines; 3.78 is the stroke for the 390, 406 and 427 engines and 3.5 is the stroke for the 352 and 360 engines.

 

Until a recent valve job, I had no idea whether I had a 360 or 390 in truck. THe Vin and Air cleaner said 360, but the valve cover and previous owner said 390.

So what I used to do was go to online shopping sites and fill a cart with the parts that I wanted for a 360, then I would do the same for a 390. And of course almost all the time, the parts were the same. (As we all know, the 390 is just a stroked 360.)

So I'm real surprised AC Delco is selling different parts. (THen again, isn't AC-Delco a division of GM?)
