Fuel Pump

[ktm380]

Found out the hard way that the fuel pump is not working. Changed out all the fuel filters today and I could not get it to prime. I did some searching and found alot of good info but where can I get a new pump. Saturn does not have them and I did not find the external one's that have been talked about here on past post. Also would it be possiable for some to post a pic of the bottom of the pump, It looks like I'm missing the bottom cover.
Help please!

If your looking for the tank pump Memphis Equipment has them.They also carry just about everything else you could need.

If you hunt through the Saturn listings they do have an external 24V fuel pump for $36.50.

I wish the search function would work for the Saturn site, every time I try to use it (even though I hit the "Search saturnsurplus.com button) it does a Google search. They used to list a kit for installing a low air pressure light in the dash but I can't find it anymore. All I can find now is the kit with a new air pressure guage, and I don't need the guage, just the warning light kit.

Hotshot, I will call them in the morning. Any idea of cost?

Houdel, That is the one I was looking for I might also get one to carry as a spare.

Houdel, the google search that happens when you search Saturn, is a google of 'just' saturns site. It should return what you need.

I have also heard somewhere that the external pumps they sell do not flow enough fuel for the deuce...

 

[ktm380]

From an old post found here I found the flow rate is less, but I think it will work to prime. My internal fuel pump has never worked.

Also, its been found that if you take the fuel pump apart, ususally you can clean everything up and make them work again. Of course... I should try that on mine, as it hasnt been working in quite some time.

The shim is on the right and I think I'm missing some. I only have two on the pump. Can't find any in the tank. This pump has not worked for a long time.

Here's what my pump looks like.

I also just found out those pumps are absolutely worthless unless they have the bottom cover. You could probably make a shim and cover out of some sheet metal and save yourself alot of money. Just use precision cutting with a jig saw. Beats spending $150 on anotherpump. I would triple check the tank, I bet its hidden in a far corner. Good luck.

 

[ktm380]

How can I get to the far corner of the tank? Looking around the shop for some sheet metal. Is the bottom completly covered (Blanked off)?

 

[Djfreema]

There sould be gaps in the bottom. Try using a coat hanger to fish around in there. I was able to use a coat hanger to pull a Q-tip that fell into my VW 1.9 Diesel cylinder during an injector nozzle swap (long story). If you can get a flash light and mirror in there that could help you see. Definately drain the tank if you can for best visibility, theres a drain plug at the bottom of the tank.

the pic of that shim came off of my tank and I'm so lazy I havent put it back on yet, can anybody tell me what actually holds the shim to the bottom of the pump?

 

[ktm380]

Ok so I went fishing and found all the parts! a piece in each corner, Tank was almost full and I don't have can's to empty it. The parts are just the right size to go though the little gaps.

The shims are held in by the cover. I think the cover in pressed in, I drilled some holes and put cotter pins to help hold it.

Put it all back together, primed it, started right up no problem. Seems to have some more power now!

pics backward,

I love it when a plan comes together!

 

[rdixiemiller]

from the pictures that is a standard design centrifugal pump. As said, it will not work without the bottom cover! It will also not work without the "shims". Those shims form the pump body, which is shaped like the numeral "9". If you look at the pump, you notice that the open center of the "shim" surrounds the impeller. The inlet screen is centered on the impeller. As the impeller rotates at high speed, the liquid is accelerated around the pump cavity. As the fluid at high speed hits the "tail of the number 9" shaped section of the pump body, it shoots through the opening and goes up the tube to the engine. You can see that if the pump is running backwards, it will not pump. If the liquid does not completely fill the pump cavity, it will not pump. This design pump is very efficient, and is used in all sorts of commercial, residential, and automotive applications.
I like the cotter pin idea! I have read several posts about the pump falling apart in the tank. That is some fine "field engineering" in action! If I ever have to pull mine, that will be a modification I perform.
Glad you got it back running!

 

[ktm380]

I must say that the cotter pin idea was the wife's, she helps me out a lot. She played with alot of planes when she was in Air Force.

Looks like you're on the right track. The only difference I can see on mine is that the plate is held in place by a length of wire laced in and out of the holes. I can set my pump on my scanner and get a picture if you like.

Now that I gotta see

ktm380,
If you are NOT satisfied overall with the results of your current fix, let me know. I bought four pumps off of ebay a while back. Three work, one does not.

You could have the one that doesn't work for free. You pay shipping. Or drive up from Pueblo, I'll buy lunch.

Of the three remaining ones, I gave the NOS one to RandyLBarnes. That leaves me with two that may or may not function properly, though the seller said they do spin the motor when powered up. The fourth one, as I said is DOA.

If you wanted one of the ones that may or may not work, or the DOA one, let me know. I'm not in this for making money. WE GOTTA HELP EACH OTHER to keep Green Iron on the roads.

Let me know.

Sorry, but I must have missed this thread before. Plus I'm in super overdrive right now trying desperately to finish a ton of projects before a buddy of mine shows up next Thursday from FLA. I have not seen him in over ten years.
