need fuel pump help quick!

[thebeewantsboost]

i was using an ac delco fuel pump rebuild kit, on my dads oldsmobile alero. it has the same sytem as our vehicles as far as there is a bucket. i broke the plastic elbow at the bottom of the bucket that the small hose hooks onto to fill it. it had a ball and spring in it. and on the inside there was a little rubber that would close over the inlet whenever it wasn't pumping fuel into the bucket. is it a bad idea to cut a hole in the bucket to allow the gas in the tank to cool the pump. i know most people do this if they buy walbro kits. or is there a better option?(without buying a new pump assembly)

Use hose clamps to clamp everything together and ditch the bucket.

Re: need fuel pump help quick!

did you use that method on your car? ever have trouble sucking up air when the tank is low? its my parents car and i would hate for it to take a dump. i wish i would have been patient and used a heat gun.

1. How in the world did you break that?

2. The car will have no venturi operation, the pump draws fuel from the bucket and the venturi keeps the bucket full. So they may run out of gas prematurely. Getting rid of this system is a hack job way of installing a pump.

Best bet is go to the wreckers and get a used bucket and put a walbro from Racetronix in there that retains the venturi function. (Probably a W body pump will work)

i understand how it works, the ac delco pump retains the venturi. its easy as hell to break. i was impatient and didn't heat it up. its installed with the bucket cut and running like ****.... idles fine but underload it'll fall on it's face then climb 5,000 rpm and fall on its face, on and on.... hating life right now. i know its not an ideal install. but its been done for a long time. even from the factory. i think its the pump, but not for certain

Yes mine is clamped all together.

do you think it could be the bucket? i doubt it....... don't think its a kinked line or else, it wouldn't just be wot... sounds like the pumps not movign enough volume.. just not sure if its a weak pump or if its because theres no gas there...... but there has to be gas there.........fml

Well now I'm not sure what you broke lol, the tube itself?

It sounds like the pump may be leaking in the bucket. You should find a picture and show us what you broke!

Re: need fuel pump help quick!

Re: need fuel pump help quick!

Can't you just show us a picture from online? But then again you have to pull the tank again anyway! That sucks :(

the black hose comes off the small brass nipple on the top of the fuel pump... the plastic part of the pump bucket housing that is circled is what broke that hose was supposed to go over it. and inside of it was a spring and a ball i think.

Re: need fuel pump help quick!

Yup there was most likely a spring and ball in there.

What you should have done is cut that black venturi hose as close to the original brass nipple on the pump as possible. and then justn ot touched it the rest of the time. These old buckets the plastic can be pretty brittle and that stuff is bound to happen. I would definetly try the wreckers for a used bucket now though, I think that bucket is kaput! For that pump to work in that bucket now you would need to block off the brass nipple, which would be hard because of the pressure in the pump and the fact it is submerged in gas :(

and then "justn ot touched it?"???? just not touched it?
the hose is on the pump just the part where it normal goes into the basket with the ball valve is broken off... when it was in the tank the small hose was actually sitting in the correct position just without the ball valve. seems like i could have also just put the hose in the bucket and not cut up the basket.
