3rd pump’s the charm

So I picked up a Bosch 044 fuel pump for a song, and decided to get rid of my Fuelab Prodigy pump. I almost wrote about the Fuelab install, but since I intended on replacing it, it wasn’t worth it. It was just too much for my vehicle, even at my target boost levels.

The Fuelab pump was brushless, and so was very picky about voltage. It was unusable during cranking due to a large voltage drop because of my small battery. So I had to add in a check valve, which helped, but I still needed to do a ten-fold increase in my cranking pulsewidth calculations. Then there was the speed control wiring. It was too much ‘because racecar’, so I decided to swap to the Bosch when offered.

To my surprise it came with a check valve integrated in to a type of banjo fitting. But, since I already added a check valve closer to the fuel rail, this would be redundant. Also, banjo fittings flow poorly.

A couple of new fittings and moving the mounting brackets over a bit was all it took to get it installed. Note all the holes for all the difference bracket configurations on my mounting plate. Heh.
