Mechanical fuel pump...parts help/rebuilder.

Not sure if this one will work or not. here

Better yet, contact the guys up at IH Parts America. Not every part they sell is listed in the online store.

I have a '66 1100a with a side-mounted bowl type fuel pump, mechanical. I read a thread by m. Mayben refering to a shop in ma with service and parts...anyone have another source? My diaphragm is blown out and leaking fuel....

Here's the reference mm gave,

fuel pump rebuilding kits - then and now automotive

Thanks,

Thats the place,last I looked it was $85 for the kit.then you gotta ask yourself,whats my time worth ? Go thru the hassle of rebuilding it or just buy 1 already to bolt on ? Jeff

They charged $97.50 with shipping...

I just hooked it up and I don't seem to get much pump action. Did I miss the eccenter lobe on the camshaft somehow? Eh, first time putting one back in...was I supposed to get the arm for the pump in there a certain way...or prime it somehow? Battery getting low...lol
 
I don't understand what you mean by "pump action".


Have you verified that it is not pumping fuel?
Measured fuel pressure?

Hard to screw up the install.. The eccentric lobe it right there..
You might remove the pump and look for a witness Mark on the arm/eccentric wear surface.. Won't be big but you should see that it is rubbing in the right place...


No? Call the rebuilder and complain to them....
If everything is up to snuff in the fuel system it should prime up in 15 seconds or less of whirling over.....
 
It seems hard to screw up the install. Went right back in. I guess the question in my mind was 'is the arm above the lobe and not getting pushed by it as it goes around' or ? The glass fuel filter bowl didn't fill nor did my secondary filter before my carb. If the lobe is activating the arm and thus the diaphragm I would think it would draw fuel but since it didn't I was wondering if I had to 'prime' it by adding fuel to the glass bowl or something...again, I've never re-installed one before. I knew enough to make the gasket seal good to the crankcase. I will disconnect the 'out line and see if it's pumping but since the glass bowl is empty I would think it is not. It just seems like I don't have the arm on the pump 'under' the lobe so it gets hit/pushed ... ??? without seeing the internals I can't muster much other guesses...it was rebuilt and bench tested for proper action before being returned to me so I have to assume the pump is working properly for now...anyway, I'll get to it tomorrow...too many other things to do : ) heck, maybe somebody stole my fuel...lol
 
I take it this is a v8 ? How long has it been or has it ever ran with a manual fuel pump like what you had rebuilt? Hook up a gas line to the fuel pump an put it in a jug of gas,hang it from the hood . Then try starting it while trickeling some gas in the carb,if it don't fill up the glass bowl,then you got a problem with f.pump,or the ecentric on the cam gear is not there,or is loose ? Or ?

Jeff,

the pump has been out of the truck for only a week and a half. The engine was running very well before the diaphragm leaked. I am charging the battery a bit, adding fuel to the tank for good measure, filling the glass bowl and giving it another go this morning...I think it was just sucking too much air. The fuel was out of the intake line from the tank as well as the pump being dry makes me think it just needs some fluid in it to pump properly...but again, what do I know...lol. I am having fun though...:yesnod:

Be judicious with your starter motor cranking duration and intervals. If you're cranking enough to run the battery down, I see cause for concern. Overheating the starter motor from extended cranking is the surest way there is to dramatically reduce its life span. Crank duration should be no more than a 15 second burst followed by a brief cool down interval before the next try.
 
Thanks for the advice guys...I do use the burst method for starting. I stopped just short of the battery slowing down and am putting on the charger this morning. I'll get to it after lunch when the battery is fresh...
 
Okay, I charged up the battery for battle and found the following:

fuel was pumping
glass bowl was full
secondary fuel filter pre carb was not filling
disconnected line in fitting to carb and all was good
took a ball peen hammer to the carb and freed up the float bowl
truck fired up

the damn float bowl was stuck not allowing fuel into the carb. A.k.a....the usual. I figured it out as soon as I knew for sure fuel was getting to the carb....been there, done that. Whack, whack ,whack or tap, tap , tap I should say and problem solved.

So when you 'dry out' your carburetor it is a good idea to tap the float bowl body to loosen up what will usually be a stuck float bowl not allowing gas into the carb....grrrr.

Pump is perfect. Truck runs awesome!!!!!

I want to personally thank everyone who chimed in on this...thank you : )

Glad you got it. Not sure I subscribe to the blunt force method. I know it was applied gently, but even so, that metal is pretty delicate. I could be wrong, but to my thinking, if the float stuck once, it can stick again. Maybe the next time it will stick in the open position. A float that sticks in either direction is not a normal condition. This could be an indication of another looming issue.
 
Michael mayben rebuilt the carb two years ago or so...my brother in law just rebuilt it a month ago...he's a guru as well. Just one of those things....but all is well now. :yesnod:
