fuel system build

[617mach 1x]

hey guy, my stock fuel system is taking a dump here soon, anyways i was just wondering if any of you have ever used this fuel pump from holley ?

HOLLEY 12-1400 HP IN-LINE BILLET FUEL PUMP EFI OR CARB | eBay

and if anyone has pics or anything of how they did there fuel system post it up!

Dont know much about that one, but I think if you are going this route most people will recommend the aeromotive 1000

Not sure how I missed this thread but I have considered this pump as well and like it has been mentioned, I went with the A1000 mostly because that is what people have used and it was REALLY close to this pump's price.

This isn't to say that this pump wont work as it appears that it most certainly will but it is not a lift pump. It needs to be mounted either even with the bottom or below the tank. If I were going to run this pump on my truck, I would recommend at least a sump and (since I believe in two pumps over one) a low pressure airdog or fass to feed it. Once those are done, I have every confidence that it will flow more than enough fuel for whatever injector needs you have. You will also need a RR kit (unless you just keep the stock regulator going). Hope this helps man.

thanks man, it does, i was going to use this pump, since it was rated for diesel and flows plenty for the truck

thats the same filters setup i have waiting for me on the shelf

WVO BIODiesel Dual Remote Mount FRAM PS3712 Fuel Filter Water Separator Included | eBay

getting all the parts and making my owe RR kit also deleting the stock fuel system completely

was planing on

sump, filters, pump, y block, into the heads, y block, single line to regulator then back to the tank

Well for the record, the A1000 and Fuelab pumps are diesel compatible. It says it in their instruction manuals.

On your setup, I HIGHLY recommend getting some sort of lift pump to feed the holley pump as the Holley pump is NOT a lift pump. It does not really produce any suction to draw fuel out of the tank as it is a positive displacement pump (hence the fact that it is a high pressure pump) and these sort of pumps need fuel pushed to them so they don't cavitate and fail. Again, I'll put the plug in for the airdog or fass as they allow you to do all of the filtering you need and removes entrained air. Yes it is expensive to build a system this way but i really feel this is the best way to do it. JMO and hope this helps.

take my advice

Pump Fuelab or Aeromotive (I've used both, I like the Fuelab more because its quieter inside the cab)

Filters I highly recommend you put a prepump filter and a post pump filter, dont put them both before the pump.

what are you trying to say here? This is not a proper way to regulate off of BOTH heads. You need to run a line off each head to its own port on the regulator and then send it back to the tank from the regulator.

He was trying to say that fuel flows from the pump to a y-block where it splits and goes to the heads, then comes out the back to a y-block that brings it back to a single line that goes to a regulator and sends it back to the tank.

Now as far as whether you send lines from both heads to the regulator or tie them together into a common line with a y-block and then send that line to a regulator doesn't matter. It's all based on pressure anyways. If one side flows slightly faster than the other, it wont matter because it is all just total flow that builds up to the set pressure at the regulator and then bleeds the rest to the tank. This is at least the way I have understood it to work. If this is not the case Greg, let me know why so I can be smarter about it.
