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?

They make good pumps.

I have a Weldon 2035. Pressure started dropping at about 1250 rwhp at the track. I added my old Accel DFI pump that I used on the Cobra. It flows about the same as the 2035. They aren't too bad if mounted properly. Here is the video of the Weldon that was bolted right to the car with no isolators.

If I can make room I am going belt drive this winter.. I don't like the idea of two pumps.

sheez, just makes a little bit of noise

hope the magnafuel doesn't make quite that much

are the weldon pumps user rebuildable?

what is your used weldon pump worth?

thanks

Silly electronic fuel pumps...

[DaveH]

The 2345's are rated continuous duty but the 2035 isn't. Weldon makes a fuel pump controller so you can use it for continuous use thought. You can hear the 2345 in this startup vid at 0:19.

A new 2035 is about $850, Dave's pump is over $1000.

Guys are getting around $500 for a used 2035.

Weldon FAQ says send in for repairs. I have not heard of too many issues with them unlike the A-1000. I was running the A-1000 in my N/A set-up with no issues. I think it is on Christian's car right now.

yeah then one shits under full power and bye bye engine

Id rather have just one pump quit and loose fuel altogether than have one pump out of the two quit and let the engine still be running in possible serious lean condition

[zbrown]

and how big of line are you guys running from the pump forward?

I was running a -8 N/A and spray. Now a -10

[DaveH]

-10 AN here also.

lol that means -8 for me,

what regulators for you guys, and do you have a filter pre and post pump?

I should have just named this thread ..."the really fast guys' fuel systems" haha

thanks

[Christian]

-10 AN for me too and -8 back . Just do it right the first time so you only have to do it once.

I had the Aeromotive on the Cobra, when I had two pumps on that it was not returning enough of the fuel to the return line. I borrowed Dave's Weldon and it cleared that right up. The Orange car had a Weldon on it. With both pumps running base pressure goes up maybe 2-3 lbs at idle. Either one should be fine. Also run two filters, one before the pump and one after.

You guys run and bend hardline the length of the car or just run SS braided the whole way up?

thanks for the input:icon_thumleft:

[DaveH]

I run an Aeromotive Pro pre-filter and a Aeromitive standard post filter. Braided line the whole way, no hardlines.

I have -12AN line from the fuel cell to the pump, then -10AN from the pump up to the engine bay, I have a Y-block in the engine bay where it splits to two -8AN lines and each -8AN line goes to an end of the fuel rail. I got the Weldon 2040 regulator.
