First, sorry guys, not sure what forum to put this in. Mods, please feel free to move it if this is incorrect forums.

Yesterday, my Radix in-line fuel pump starting making a REALLY LOUD whining noise while i had my truck running sitting in my driveway. Today, it started doing it again while i was driving and i noticed my fuel pressure starting to drop alot. Is the fuel pump going bad? If so, will Magnacharger warranty it? If not, where can i get a new one and how much are they? thanks.

 

Mine went bad I replaced it with a Edelbrock #1794 fuel pump mounted on the chassis rail next to the fuel tank.I used the Radix relay and lengthened the wiring.

 

$600!!!!!! HOLY ****!

 

Depending on how long you have had it you will be under warranty.

Holley makes a similar in-line pump. I think it's a Walbro...anyhow I had one on my Chevelle when I had the Commander MPI 950 on it. It fed my 454 very nicely. I think the cost is around $150. Later

same thing happened to me on christmas day. no idea what happened but it's working fine now.

 

Thanks Brian. I called Magnuson and spoke to David. He said i have to buy a new pump and send my old one back. If they find it defective they'll credit me back my money. Its gonna be $125 which i don't have right now. Guess i'm kinda screwed without my truck for awhile until i can come up with the cash. bummer.

also, what if they say its not defective? i mean, it dosn't make this loud horrible noise 100% of the time, and it just started yesterday. Maybe i'll wait until it just stops working completely.

 

they do tend to make some noise.....If the fuel pressure is dropping, then I am sure its an issue. let me see what I can do for you.

 

Mine started making a very loud noise as you described when it got really hot, and then it wouldn't add any additional PSI to the stock pressure. If I let it sit and cool down it would work fine again for awhile. I replaced it with the Holley/Walbro unit as mentioned above and it's been fine. Mine lasted about 2 years....how old is yours?

 

Mine is only a few months old. It deffanetly was not over heated though.
