MitsuStyle - View Single Post - How much amperage should twin fuel pumps pull?

**4seasons69** · 02-18-2013

I got my car running yesterday and it's popping the 40amp maxi fuse for the fuel pumps. We put a 50amp in that we had laying around and it ran fine.

The pumps are twin walbro 310lph pumps (Ford gt pumps) with a single power feed. The things I changed this winter is I rewired the sending unit with 10 gauge wire and replaced the strainers on the pumps. I did not use the same strainers that were on there. I used ones that a lot of people on the Ford forums say work well with these pumps and they were in Stock at a local parts store.

Are the new strainers just making the pumps work harder, is it the bigger wiring?

Should I just rock a 50amp fuse or figure out why these pumps are now blowing the fuse. Any input and advice is greatly appreciated!
