Front plug thread size????

any of those three would work. i am sure dude above just tried to find you a link and didnt look closely at the specs

only thing about the 13105 is that if you use it behind a p-7100 you have to do two tees. one for the inj return and one for the gauge

you posted while i was typing

again

lol

i heard p-pumps dont like over 50 psi

then again i also was told my truck wouldnt run if i gave it less than 20 at idle and it ran fine at 5

i thought it would be benificial to boost ref the pressure but someone got me paranoid about the diaphram not lasting as long plumbed that way so i disconnected it and changed the spring and set it at 40

its loud as hell now and i am thinkin about switching it back

the diaphrams cant be that expensive - i'll put a spare in the glove box

The overflow location and front plug are both open to the pump body, it's called longitudinal scavenging.

there was a picture posted on here that showed where they meet inside the pump

who posted that pic???????

jim, do you think there is a way (pump would have to be out of truck and apart for rebuild) that one could reroute the passage from the front plug so that it went into the main pump body instead of out the return?

I look at this as you are asking my opinion so here it is, don't over think this stuff, too many people way over think stuff like this. The only reason I ever ran a second feed is because I still run the stock fueling system and that requires using a -6 line so I knew it wasn't enough, give me a -8 or even better yet a -10 and I would run a single like and return it in the normal port or even front.....doesn't matter.

i run a heads up class - have to think outside the box - which is good cuz thats how my mind works

but this is just common sense stuff here

do you think a -10 line will put more fuel into the pump body (thru the tiny inlet fitting) than a -6? if you didnt change the pump, only the line size?

It's about heat dispersion, if fed from the stock location, the #1 plunger/barrel will receive the highest temperature fuel at less density. I am assuming this is the picture you were looking for, Jesse posted it in another similiar thread.

That pic is awseome Weston! I take it you're an advocate of dual feeding the pump then? What do you think about using a T to split the supply from my AD 150 to the stock location and the front port?

if you do that (as many have) where do you think the fuel goes once the body is full?

liquids under pressure will take the path of least resistance

so you may as well not even use the stock inlet - cuz once the body is full this is all you got:

okay, so you got it plumbed with two feeds

one comes in the middle of one side and the other next to the return

you think the fuel used to get hot by #1 with a single feed?

how hot is the fuel at #6 with the dual feed?

with the dual feed #1 is the only thing that is getting cool fuel, the rest of the fuel in the pump is stagnant

If you look at a M14x6AN fitting verses an M14x10AN there may very well not be a huge difference between the two but think about the supply to the inj pump, a -10 line is a huge source just sitting there waiting to be used.

at what HP would someone need to upgrade the fuel lines and stuff like this?
Click to expand...

Lance, for me about 500 hp and about you need to do something different! To date and even throwing my own setup under the bus I'd say an Airdog 150 for a replacement, I've seen it and like it, even thinking about it too for my truck.

some have made 700+ with a stock lift pump

but there are other benifits to a good supply of cool dense fuel besides its ability to make power

jim i like the idea of your mech/elec twin pump system
 
i asked someone that i trust and that is what i was told

if you are so tired of it maybe you shouldnt frequent the site?
 
lol

act accordingly

i personally have both the motor and the dyno sheet - 473" 795 hp w/ a mech fuel pump. yes, its a gasser but if it can be done with gasoline why not with diesel?

i should have stated "I WAS TOLD" above - my bad
 
I still have a factory mech. pump in place and make 700+
Its not working alone though.
 
what about a sumped cell up in the bed flowin thru a free flow aeromotive 100m prefilter?

some air tight fat lines ran right into a piston pump

put a diff spring in it so you can use a reg @ 40 psi on the other side of the ip

and a big 2m filter between the two??? (piston pump and p-pump)

wouldnt that move enough fuel to support the numbers smokey is asking about?
 
I have a large sumped cell in the bed with big -8 feeds into a 110gph 12v modified fuel pump then into the suction of a new factory mechanical pump, from there its filtered then single feed -8 into the inj. pump. Although I have the 18mmx1.5 fitting on the way to go ahead and wye off and pick up the front port as well. I also run no reg., just a tweaked overflow valve, I keep it ~45psi at idle and it burys the 60# guage down track. Numbers say I need just noth of 1000 ponies to reach my e.t goal..... im getting mighty close. There are multiple ways of doing everything and making it work, the main thing here is not starving your IP of needed lubrication and maintaining a decant pressure while under a load, with todays fuel lacking the nedded sulfer to help lube the pump I highly recommend people using some sort of lube supplement to help the parts live. Store bought stuff, 2 stroke oil, tranny fluid, ect....

My brother runs a similar setup to you and he is at 600hp. He has a all stock motor internals. 5x18 dual feeds, no plate, no afc, 22*, CDS 5k springs, stock lift pump and a silver bullet 66. Tim

found this in another thread

i know there is a huge diff between 6 and 700 but thought i would quote it for those interested
 
okay

but please respond to my post from above:
