Fuel leaking out of a part that I can't identify!

Asked by Oct 17, 2015 at 05:50 PM about the Mazda B-Series Truck

Question type: Maintenance & Repair

I have a 1991 Mazda b2200 that has started leaking out of a part that I cannot
seem it identify.  It's a manual transmission, and this part is on the firewall
side of the motor, close to the carb, and seemingly attaches to the block.  I
just need to figure out the darn name of the thing so I can replace it....thanks
all!

The picture is rotated counter clockwise by 90 degrees, the two lines with the brass looking fittings are fuel lines

That is the fuel pump.

I wondered that, myself, but when I looked up a fuel pump at auto zone, it didn't look anything like this part.... Also, I'm not seeing any 12v power goin to this part..... Am I hearing that the fuel pump is (a) not in the fuel tank and (b) vacuum driven? Thanks for the help!

It is called a mechanical fuel pump, it is not vacuum driven but it driven off the camshaft, so be careful replacing it, you might also consider replacing the fuel lines, they looked cracked in the picture.

Well I'll be darned, I guess there were 2 types of fuel pumps and I only saw the 12v ones.... I saw the part in a couple breakouts that looked like the one I needed (second pic down bottom left http://www.mazdatrucking.com/B22 00/Vacuum.html) but no sites had a definition for it.... You saved me some serious time tennisshoes! Thanks so much!
