Drip, drip, drip... The fuel pump on my '63 F250 262 isn't looking too good.



Q: Better to rebuild or replace?

If replace, is this NORS #241 pump the right one? Says its for "1962-1963 Ford Light Duty Truck 262 6 Cyl"

Or is a more modern pump available that bolts on?

 

It would appear - based on further investigation - that Bill (aka "NumberDummy") suggested in another thread to...
With that in mind... Has anyone done this and, if so, which pump did you select, why and how is that working for you?

And, given a 'behind the seat tank', where did you end up placing the electric pump?

Thx in advance!

 

My old man did that with his. It works fine, just make sure you get a high quality pump (I prefer rotary) and maybe even a spare to throw behind the seat.

Personally, I would either find a new mechanical pump for yours, or the parts to rebuild it.

 

I prefer mechanical pumps for the most part.

Keep in mind though - NOS parts may not have been stored properly, the rubber components may be dry rotted by now, and they may not stand up to modern fuels. Same thing with rebuild kits., the rubber may not be ethanol tolerant.

 

Thx for the replies and comments!

Thought I'd rip the heart out and perform some open heart surgery to see what's what.

Here are the initial pics:







If you see anything concerning, plmk.

Next: Lots-o-cleaning.

More to follow...

 

After "initial" cleaning...

 

After final cleaning, painting, and install...

 

Some of you will notice there's no line out from the pump. Reason: I sort of destroyed it while extracting the pump yesterday... That's my last item to address prior to testing and "relaunch"; likely tomorrow.

Note: I ran compression on the pump and everything looks solid. Other than significant cleaning I replaced 2 gaskets and a spring. Both gaskets looked pretty bad and either could've been my leak culprit.

Again, more to follow...

 

Did you disassemble it? I was waiting to see the innards.

 

I did, but... the pics were after dark and so blurry as to be indistinguishable. I've not posted them.

Internals all looked and manually performed great. The top gasket for the chamber where the in-out plungers are exposed was noticeably deteriorated so I cut a new one; as was the main engine gasket. It too got a new cut gasket.

Apologies on the pics. Wish I'd taken better images.

 

So the initial gaskets didn't seal.

Then the attempt to reseat and add Permatex #3 didn't seal.

So, I ripped it apart (again) and reset gaskets with Permatex "The Right Stuff" and, well, it would appear to be holding so far; kinda like me with my breath until I can say the seals are solid...

Nevertheless, while apart, I took more pics:





In the second pic there is a partial ring clearly visible from where the plunger metal center must be striking the bottom of the upper chamber. Not sure how concerned I should be about that as it's likely been doing so for almost as long as I've been alive and still seems to be working fine?

 

Hm, dunno. I will say that it's the gaskets that make the seal, there isn't hardly any goop or sealant I'm aware of that will hold up to gasoline. Did a rebuild kit get installed? Sometimes when a fuel pump fails it won't leak externally, instead it will fill the crankcase with gasoline.

 

Update:

I gave it the "old college try" and, well... No joy. The leaks continue.

I'll likely install a block-off and electric pump & regulator tomorrow; and stash a backup behind the seat. Frustrating.

 

Silicone will dissolve in and turn to snot when in contact with gasoline

You need to use something like Threebond 1194. It is gasoline resistant, it should do the trick.

 

Any update on the fix for this fuel pump I have the same issue with my 262 in my 62 F100. I would like to keep the fuel pump rather than going to an electric pump. I am not able to find any gaskets to rebuild this pump.
