Ok I know Got-Torque has had some talk of his set-up in various threads, but I wanna get it all concentrated in one place.

I am going to be feeding a 550cc 12mm pump with a FASS 150. I have to send my fass back for a bigger motor to hold the high pressures but what else do I need?

will 1/2" lines be enough? should I Tee it and do the dual feed on the pump?

will I need some type of external regulator? or will the pump do this internally?

what size fuel return is needed? can I just tie it into the existing vp44 return line or is that too small?

I do have a few posts out there on my setup...

You will need the higher psi spring for the FASS (I think the 45 psi one was recommended). I reused my 1/2" lines.

I was told a dual feed was not necessary on a 550 cc pump, but I did it anyways. Much easier to plumb it all up when the pump is on the bench instead of changing things later.

I tied into the existing return line. If I did it again I would replace the hard lines and the factory tee with better pieces. I've fought mine alot to stop the leaking from the factory tee connection.

External regulator is not required, I added it just to prevent the FASS from running at 45psi all the time. However, my regulator isn't working and I see 40 psi all the time. I'd probably just skip it if I did it again...

thanks buddy, i will look into replacing the factory lines. Prolly cut the banjo bolt line going to the back of the head and use a flaring too to put a small flare on it, then connect a rubber hose to it and use JIC pushlocks on everything else like I have with my supply lines.

when you gonna post all the pics for me LOL

also- what type/style of fittings is used to tee off the oil line to the vacuum pump to feed the p-pump? i gotta make a list so I can get them all at one time.

How soon you starting the swap?

I didn't tee into the oil feed port for the vacuum pump. I used the next port to the rear. Metric threads to AN4 (I have the specs at home), then AN4 hose to the pump. I still need to go back and pull the fitting out (at the pump) and thread the inside of the fitting to insert a plug with a 5/64" hole in it. Right now it is a full 1/4" line which flows way too much oil to the pump...

post pics of that also...my buddy is a machinist i will have to get him to modify the fitting for me also

hey tj, i had a guy tell me that they have done quite a few of these conversions and they have been putting the raptor pump in front of the fass, or air dog, they tell me when you change the spring that it takes life out of the pump. i think that the raptor is adjustable so you can set it at whatever pressure you want.

For your return lines you can use a 90* fitting in the back of the head, it is metric thread and you can get the right fittings to do it all with hose.
You don't need a dual feed for 550cc but if you want to instead of drilling and tapping a hole in your housing you can take the plug out of the front above your rack cap and install a metric fitting in there also. I can get you the fittings you need let me know.

does anyone know what those metric threads are? i have a local shop to get all these fittings, just need to know the size.

also is -6AN line big enough for the return since im running -8AN for the supply?

That's what I'm using...Actually, I'm using the stock steel feed line on the frame for my return!

Return in the back of the head is a M12x1.5 metric straight thread

thank you.

i see you have an 01 p-pump 24v...any more tips on this plumbing? how about for the oil feed?

Use one of your ports back the block from your ps pump feed and run the line to your p pump, swap your feed line from the engine side to the throttle linkage side. Do you need throttle linkage?

yes i need throttle linkage, and a pump support bracket

When I did mine, it was cheaper and easier to buy a new hi pressure unit, then sell the old one for a half decent price. I think it was around $300 or so to get the bigger pump for my FASS 150. That was back when Doug owned PDW.

It's still the same price, got mine thru Garrett...

So a air dog 150 for the VP44 wont work with the P-7100 even when you up the feed pressure?

Tate

It should. I ran my 18psi FASS for a couple months with no ill effects.

The P7100 needs atleast 35PSI at all times

18psi with a p-pump is like ZERO psi thru a VP44 :bang:badidea: Very very bad!

Dang guys I only run 15 psi at WOT using the stock lift pump, add the A1000 to the mix and it's at 50, with a 13mm pump it would pull down to 3 psi, been running some sort of high end pump for 5 years now.

if you turn the pressure up that will work but will probably take the life out of the motor on the pump. you can buy a raptor and put inline to set the pressure up, they are adjustable. just install it between your airdog and the p pump.

I do not believe that the AD has adjustible pressure.

Factory specs are only 18psi idle, 25 @ 2500rpm. After 200,000 miles of 25psi I don't think it will fuss if you leave the pressure around there. Although, it might like a little more

Also remember that they are talking 550cc's of fuel instead of the 200ish stock...for all our "big" P-Pumps we recommend 50-75 psi all the time, these are competition only pumps, but the same ill effects will be found on a street/strip/puller P7100...

So would i keep 20psi on the 150 feeding the high pressure pump?


Are you guys coming up for our pull on the 25th? I believe Ladell and Lamar will be coming down.

2000wvdodge
10-11-2008, 04:32 PM
ladell told me that he has done this a few times and it has worked great. he didnt tell me the pressure, i never asked to be honest. this is what im going to do when i do mine sometime this winter/early spring.

as far as if we are coming down or not, thats a jeremy question. im gonna try to pull my truck this weekend for the first time since my crash, so we'll see how that goes...

10-12-2008, 01:16 AM
Do you trust east coast with pump work? Aot of people around here dont like thoes guys for anything, I have had very good experiances with them. I mianly deal with Ladell but they are nice guys, dont try to push products on you...

I am looking to get a 550cc 4,500rpm pump. Columbus diesel supply wont call me back, the local pump shop wants $3750 for one(He does the best work around). Would you recommend East Coast to make a pump?

2000wvdodge
10-12-2008, 01:43 PM
yeah, they are doing mine. pm timebomb and see if he can get you a 215 pump, then call ladell and see what he can do for ya. we compete against them guys but that doesnt mean that i wont get work done from them. they have done all the work on their trucks and many, many more up in that area, so yeah i would let them do it for you.:rockwoot:

It doesn't gain anything, and side loads the plungers, causing excessive wear...

I talked to Ladell many times and been up there. I got my head, airdog, turbo all from them. They gave me a very good price for a pump.

I am going to be getting big pump from airdog i think to replace my current FASS set-up, is a 1/2" (-8AN) line with a y-block dual feeding the pump going to be enough, or should I go 5/8" (-10AN) to the y-block with dual 1/2" to the pump then

I got in touch with the folks at AD and they sent me out a spring to change the output of my FP150 to ~40lbs for when I do my conversion. Just a heads up b4 you try to sell yours or go buy something else.

from what I gathered when you put the 40psi springs in a 150 that is designed for the 24v (less than 25psi normally) it takes alot of life out of the pump and it cant keep up.

for someone going to 500+cc's of fuel with a p-pump you either need a bigger pump made for 150gph at 50psi or run an AD with a raptor pump inline with it. im waiting for AD's new big hp 12 valve version to come out, more than enough fuel!

texsasdiesel
10-23-2008, 05:19 PM
I wouldn't think that AD would sell you a spring that would kill their own pump when they have a lifetime warranty on the pump. I told them exactly what I was going to do with the pump and that is exactly what he said to do. I'm not saying that it won't take some life out of the pump, just telling you what they told me. Who is to say that the spring is only diff between the AD FP 150 for the 12v and the AD FP150 for the 24v? Then again I'm not shooting for all out power with the truck and don't need 60+ psi, and if I do, I can always get a raptor later and add it in-line.
