piston style lift pump swap worth it?
 
I was snoopinga around online because my lift pump started leaking fuel. I saw a kit to convert to the piston style lift pump for $270. Is it reallt worth it or save up for a raptor lift pump?

Depends on how much HP you want to eventually make. It is said to support ~300HP. If it's leaking don't keep driving it with low pressure because it will wear out the injection pump. I have the kit on my 1st gen and it works just fine with my setup (listed in my sig).

Uh, I think it is, you just prolly don't need those lines get an aftermarket fuel filter (remote mount like Racor) just buy the spacer and the pump, spend less on those, bypass all the stock filter and the fuel heater if its not really needed, its what I'm doing, but I'm in South Texas and winters aren't much here. :) Remember the electric fuel pumps would be whining the whole time you have the engine on, it seems to me it would get real old. :)

Get a better quality electric fuel-pump. :pca1:

I can hear the Airdog on my truck when I turn the key on, but once I start the engine, all I hear is 12 valve music.:tu:

Just a get a ppump lp, fp regulator for like 15psi tops, some fittings, two pump to block gaskets, make a dpacer just like the gasket I think it's 5/16 thickness and make the lines. then the factory line off the lp cut it n slip a 3/8 hose over it double hose clamp it n call her a day. took me 2 hours on my VE.

Like the man said, you'll hear it even if its a holley black or blue pump....but when the music starts, all is fine!:tu:
Now then, theres something about filling my crankcase is diesel that rubs me the wrong way, so I always block off the Mech. pump, run a good electric, wired into the Hobbs switch plumbed into theoil system just below the stock oil pressure sending unit.
That way if you ever loose oil pressure, your fuel is cut off.
Best to have plenty of pressure though....its hard on the IP if you don't.....

Do please post some pictures

Whichever pump you go with, just don't go over 15 PSI, use a regulator and turn it down to about 12....

sootman 12-05-2012 10:36 AM

do you have any recommendations on which electric pump to get. i'm just looking for something to support mild injectors and a s300ish turbo till i get everything else fixed then im going to an air dog II

hydroshok 12-05-2012 04:10 PM

Go with the older AirDog 150 and call it a day. Mine has never let me down and is set to 15psi. There are some for sale cheap if you look...

Go to O'Reillys and get one of the old Carter Rotary Vane pumps, usually pumps about 12 psi....and no more, but I always run a regulator, sometimes you get one feelin' its oats and its pumpin a little more. just set the regulator to 12 PSI....I believe the # is 4501, the folks in the back will know the one I'm talking about. About $80....maybe a little more, unless you have a commercial account.

I'm having the same issue not to hijack but I have a good one off my old 24v. Would that over pressure the system? What kind of regulator are you running. I got one in a wrecked race car.

geddy's uncle 12-13-2012 11:42 PM

The electric pumps you all mention.... in-tank submersibles, or mounted to framerail?

luke46 12-14-2012 10:15 PM

The one mounted to the block is the one I am talking about out of the 24v I want to know if it will work ok with my truck

hydroshok 12-14-2012 10:38 PM

You have to regulate it to 15psi, get a spacer and the line is different.

Nevermind. I'm thinking 12valve. My 24V lift pump barely made any pressure.

mkriebs 12-19-2012 03:21 PM

Soooo my 12 valve VE has the low pressure piston pump and it puts out over 15 psi. Do I need to remedy this somehow? Seems to be about 17psi.

BC847 12-19-2012 03:29 PM

17psig is fine. Won't hurt a thing. :)
