How loud are the Weldon pumps? is the pump like you have good for continuous use or no?I picked up a Magnafuel 4301
Any of you heard good or bad about these pumps?
FWIW
I have been using that exact pump for the last 2 years. It is a great pump, I had one issue with it overheating, but after sending it in and them fixing for free its been flawless. It was 95 when it overheated, i havent heard of such problems with other users though. There was older style wear plates in there that expanded and locked it up when overly hot.
I have a 74micron pre filter and a 40micron post filter. I have part #'s if you want and it will save you money buying direct rather than through a vendor.
-8feed and -6 return (Stainless all the way)
Line runs in one rail across the front through the other, out the back,and into the magnafuel fuel pressure regulator.
Depending on your power goals you may want to increase line sizes. -

I already picked up my plumbing supplies sadly
... got a magnafuel 74 micron and 10 micron filters... and the big magnafuel 9950 regulator with -8 returnsome of you may think i am retarded but i plan to run my regulator in the back of the car....going to run a high static fuel pressure and un-referenced.
I like the simplicity in the engine bay with no fuel plumbing there... i will see how it works like that, i can always change to referenced
will be -10 to the pump... -8 to the FPR.... -8 from FPR up to the front rail... and a -8 return from the FPR right to the tank
-8 will support 1k hp.... I am not crazy like some of you guys so it will suffice

What fuel pressure are you going to run? How are you going to feed the rails?IIRC most gm stuff is all now 58 psi
I will probably start at around 65-70psi (the injectors i got are supposed to be great and happy at high pressures)
if i run into heating the fuel too much i will stick a cooler in the return line because there is alot of room back there
vette guys make as much power as i want on stock fuel lines with the stock unreferenced FPR in the back so i dont think i will have any problems at boost levels less than 15psi
all i will have going forward is one -8 right up to the rail...
rail will be modded like this with the addition of a -8 feed...(with stock feed cut off flush and plugged, though still acting as a cross over)
So am i really retarded or just sorta?? haha

gas or korn? ls1 intake or ls6? seen the fuel system thing done a whole buncha times, but why not boost reference it? 15 lbs on 370 in LS motor is a pile of power, 60s def wont cut it on korn with no boost reference... just my experience. The higher pressure you run on your pump, the faster it runs outta steam (exponentially) you probably know this, but fyi. If you are on gas, you wont get your fuel trims to settle on 60s at 65-70 base FP. If it is reference @ 58 it will work (50 psi @ idle) On E85 that set-up runs out about 560 (procharged, prob about 600+/- turbo)to the tire on a returnless. IIRC, that set-up is good for low 700s on gas.

It will be run on e85 and this is on a ls3/l92 topend
maybe i will run a reference line right away then, what you say makes sense
Plan was to make what power i could support on the 60's and be able to go to a bigger injector like some high imp. 90's or more... but already have the rest of the system ready to support some more hp.
This thing is coming to you to get tuned so any ideas or criticisms are greatly appreciated on fuel and other aspects....
the combo is a 370", TC78 1.15, TH350, 3.23 solid rear 8.8

send me your vette regulator, i was just gonna order one but ill buy your old shit instead, and any of your old FI line.
You are gonna need injectors anyway and it will work fine running non referenced if you want, doubt you will ever take that car over 10psi anyway, it will be about undriveable. I ran my 65#ers out at 16psi on my buick on gas at 70psi base pressure and you know how fast that was, corn none of my fuel system would go over 12. You can get FIC high imp injectors (ball and seat, the good ones) as big as you want now so that wont be an issue -
Zack, before you get carried away, what torque converter are you running? Any mods to the th350?

Th350 is nothing special... just good clutches and bands
that is no biggie, they are cheap, and i have Schmidt in dickinson... they know how to build the th350/400's and PG's right
best thing i did was get rid of that 4l60
