Well I purchased a fuel system off the board And it has two 255lph pumps in the factory bucket. Since I plan to make 1000+HP I am adding a third 255lph pump just for safety and you can never have too much fuel. Just looking to see if anybody else is using that setup and I plan on using a pressure switch to control the 3rd pump once I get into boost. Lets see some pics. Thanks

why not just switch to dual 340s? they'll handle the power just fine, E85 or 93

Because the 255lph pumps are almost new and it only cost me $90 to add another 255lph.

If I wouldn't have 2 good 255lph pump then I would buy 2 new 450's. how much do they cost? I bought the Harbor Freight 3 way air manifold for $4.00 and a few fittings for $20 so I'll have $100 into adding a third pump since you can buy them for $75.00 shipped on ebay.

I paid $135/pump on ebay.

Yeah it was either spend $270 for the 2 bigger pumps or just $100 to add another 255lph so I went with what works and is more cost efficient.

900 lph vs 765lph though too with more wiring and heat.

Well since 765lph is way more then I need now(1500+HP) I see no reason for 900lph but if I were starting from scratch for a fuel system that would be the way to go. I don't like A1000 pumps on the street turbo Kroc I like your setup. How do you hookup the Hobbs switch ,wiring diagram, b/c I want to do mine just like that. Key on turns on one 255lph pump then once I go into boost it will kick on the other two pumps.

Im running e85 so I need the 900 lol. Heres the wiring. Just add your third pump to the diagram.

i would say twin 255s for approx 700whp, if you need more do twin walbro 400s or 450s,

if you dont like that option sump and run a prostar 750 that is good for 2000+hp lol

Previously I was running an a1000 and I like this setup much better mainly because of how quiet it is. The a1000 was loud and the pro star 750 sounds like a chainsaw lol also its less draw on the charging system. The a1000 draws like 13amps or something.
