256 y block 54 customline FUEL PUMP

Let's try and get all of this somewhat correct -

EBU 239 cu. in. V8 1954 PASS CAR - LARGE CAM BEARINGS.

DEARBORN (DIF) CASTING

EBV 239 CI 1954-55 TRUCK - SMALL CAM BEARINGS
EBY 256 CI 1954 MERCURY - TRUCK
ECG 272 CI 1955-57 - PASS CAR AND TRUCK

CLEVELAND (CF) CASTING

EBY is the FYB 256CI CLEVELAND ENGINE (CF). Two year usage - 1954-1955 LT/MT.

The 256CI was also used in LT/MT and beginning in 1955 morphed into a mix of 256 and 272 engines (engine parts), finally becoming the 1956 272CI TRUCK assembly.

So after identifying the actual engine I have I ordered the recommended fuel pump from summit with the correct psi range etc. and it came in last night and the lever is short.

Should this engine have a fuel pump pushrod between the eccentric cam and the pump lever, or should I just try throw in another FE long lever style one like I had before.


The previous pump style worked great with my carb even though it was running at to much pressure. Unfortunately they fail after a while. I feel like the previous owner had it all tuned for the FE pump, float level etc.

Honestly if someone can just point me to the pump I need that would be so helpful.

I see in the post to get a glass bowl Oem one. The other ones I’m seeing also have a short lever arm, so am I running the long arm FE one because the pushrod isn’t there?
 
From your description the pump is the wrong one and should have a long lever.

The lever rides under an eccentric located on the front of the cam. No pushrod.

The correct pump s/b for a 55 YBlock. Does not matter the engine size. The one I have, for a 55-58 Yblock, is number 4206, but I do not know the manufacturer. It is a dual fuel and vacuum pump used on Fords frm 55 to ????. This one is off a sedan. It is for sale, needs a rebuild. Just be aware that the new pumps that may be available are china junk and usually quit after a very short time, if they operate at all.

Well, that is a little difficult as there was the 1954 EBV and a 1955 EBV. Both had a different front cover and pump lever design.

What will work on a later design FYB or FE may not work correctly with whatever engine (or parts combinations) you have.

There is no 10,000 mile motor oil or one fits all parts.

Now if one says they all fit and it causes a service failure, you know who to blame.

Your engine has to be identified before any good recommendation is offered.

What the previous owner put on there is junk.

BTW - If the engine has an inline fuel filter and there is a possibility of one also being in the present pump canister (sincerely), you need to shed one of them.
 
Possibly, once that you can read and understand a WSM and PARTS CATALOG regarding how the FYB design progressed over the years (especially the early ones), you might possibly understand.

So with your interpretation, the OP is OK using any pump design.

Question answered.

Either you perform correct service repairs or you modify.
 
Yes, my interpretation is that the op can use either style of pump, either the 55+ dual purpose or a FE type like he had (which proves that it will work). He has to watch out for pressure as he stated. He might need the vacuum style pump if he has vacuum wipers, but his vacuum wipers will work, just not as good, without it.

Nothing wrong with modifying as long as done in a safe and reasonable manner. Apparently, his vehicle is already modified per his statements..

And i understand how the yblock engines progressed over the years. No expert, but aware of the major changes over the years. Just because i don't have all the manuals does not mean i can't learn about them. AND THE FORD MANUALS ARE NOT PERFECT - FOR INSTANCE THE 54 SERVICE MANUAL (I THINK) STATES THAT THE 54 V8 USED THE DUAL TEMPERATURES SENDERS LIKE THE FLATHEADS - BUT THAT IS NOT TRUE.

I got a new pump that will be here today with the long lever, and 4.5 psi designed for 55-59 y block V8s. Looks just like the FE one that was on there before but with lower pressure.

I’ll check the lines and tank and get it installed in a few days.

Thanks everyone for the help. A lot of this is me just researching and learning and getting a little reassurance along the way.

I wish there was a LIKE BUTTON FEATURE here.

Hope it works out well for you.

Can you mention the seller and PN?
 
Apparently it worked correctly as it fed fuel into the carb, albeit to strong, and the engine ran. And ran good according to the OP. Any other test ?

I recommend procedures based on my own experience. I never recommend anything that I haven't had any experience on or haven't learned in another way (books, other's experiences). I didn't make any mistake about EBU vs EBV. Tell where I recommended something that incorrect.

Always open to learning. A shut mind doesn't learn anything.

When I make a mistake, I admit it and go on. And occasionally I do make a mistake. That is one way to learn. And I don't rank on people that pointed out my mistakes like some do.

And a college degree makes me a dummy about automobiles? I know about taxes (my field of work) and the Ford automobiles that I have had experiences with. As me about a 69 LTD - know nothing about them and I admit it. Yes I am a ROAD SCHOLAR because I learned a lot by getting cars on the road.


Plus I haven't been kicked off any web sites

No one knows if it worked correctly. All that is known is it put out too much pressure.

Really? When do you think you will start learning? Not a good idea to recommend a procedure or part option without having the proper knowledge and experience. Those come-backs can get expensive and customers angry.

You seem to be a little less hostile this A.M. Were you finally able to pass that THAT'S A SPICY MEATBALL GYRO?

OH! THANX for the large type again. Seems I forgot to turn up the right ear.

OH! (again) ... Very few understand the 54-55 FYB TRUCK ENGINES. You must be one of them fancy ROAD SCHOLARS (Princeton maybe?).

UPDATE:

I got the new pump installed and checked the lines. Car is running good now again. Took it for a cruise last night round town.
