Ok, last week my Mallory 4150 fuel pump went out, 1 whole month after the warranty was up (my luck as usual)...So, I am wondering if anyone has ever rebuilt one of these pumps, and also what other affordable quality pumps may be out there in case the brushes aren't what's wrong with this thing....any suggestions?

Call them and ask how much it would cost for a rebuild.

I have already gotten ahold of them....they told me that if it was still under warranty, it was my best bet....they do sell rebuild kits, but after taking it apart, one of the magnets is broken in half, and it had gotten so hot that it had started melting the copper windings on the brushes....they sell the brushes, but I don't think I can get the magnets....here's some pics.

Depending on your definition of affordable, Aeromotive & Magnafuel are the best out there.

It isn't very affordable if it doesn't last or isn't rebuildable.

Just my 2 cents worth

very true....the pump I had was way more than I really needed, and with the car going for more street than track, I think something smaller will suit me just fine.....I know aeromotive's are a bit pricey by my standards, but I had contemplated magnafuel for a while....I need to go check and see what their smaller ones pump

I agree with the pricey part, lol. My Aeromotive A2000 has run 3 seasons now on E85 without a hicup, although it i a track only car.
It hurt writing that initial check, but hopefully, it lasts longer than I do.  :grin:

well, I had to take a hard look at the finances, and to help with the issue, I bought a QFT return style fuel pressure regulator, and all the pushlok fuel line and fittings I need to turn the dead head setup into a return style. However, it meant that I didn't have as much for a fuel pump, so, I took a shot in the dark, and decided to try the summit brand street/strip pump....it has the same specs as the mallory that failed (140gph free flow, max 14 psi, etc), and it looks like it's a reboxed holley or mr gasket, so we'll see when it shows up
