Engine/Transmission (1998.5 - 2002) any one running a -6an bigline kit

[rivercat]

Putting gauges on and wanting to know what fitings go where to build a big line kit I read a mixup bettween jic and -an will cause leaks due to diffrent tapers. Are all the fittings -an or are some npt what is the part # for the fuel pressure tap to go bettween filter case and vp?



Any one have pics seems that aeroquip is the best for fittings what about hose?



I Need help



I don't want to take everything losse and not have the right stuff to finish cause right now my ctd is all I have to drive home from work.



what is the best regulator for cutting a 4600 pusher setup back to 12-15 psi



TIA

You can get AN fittings that are NPT on one end. As well as NST too. There are a few really good manufacturers out the such as AeroQuip, Earls, ect.

There's a picture on my web. site please take a look.

I ran 8-AN from the pump to the filter and from the filter to the pickup tube. I just used a push on hose with clamp over the pickup tube. The fittings are metric, 12. 5 mm I think. I'll have to check I think I used 3 90degree and 1 straight and then the metric 12. 5 to barb end for the pickup side of the lift pump.



I used stainless braided hose, but that's overkill. Aeroquip has some excellent hose, earl's as well. I ended up covering the hoses with split loom anyway, stainless can do some nasty chafing.

thanks rman im looking into it now its hard to find fittings on summits website theres like 10 pages of them wish the wife hadn't throwed all the books out...

 

[R-N-R]

This page of fittings might help, but I would go with kit from a dealer. I purchased a kit and added to it. Aside from having a bag full of pieces left over, it was a PITA trying to make sure I had all the right parts and it did take a couple of extra runs to the store. The dealers are not making a killing off these kits, but for me it was worth my time to pay a little extra to someone who has it nailed to to exactly what is needed. Olee treated me right with a quality setup for a reasonable price.

 

[rivercat]

thanks that helps with part #s but this looks like over kill for me I just want to do the stock lp with 8# 4600 setup any other suggestions do you have to bypass the 7psi coming from the pusher around the lp

can't get olee to call me back yet

 

[R-N-R]

I thought you were just looking for some help with the p/n's for the bits and pieces, not suggesting you do all that. I am not sure what you are asking about with the bypass. With the stock LP and the 4600, you should not have to bypass anything. I had heard that the aftermarket carter pumps do not flow when they die, however now I understand that the stock LP has the same (remote) potential. with the stock 15psi and the frame 7psi, you will send about 22psi to the VP, which will return about 10psi back to the tank under normal conditions. I think what you are planning is the most typical setup for adding a 2nd pusher pump.



Hope this helps,

Bill

yes bill with your pluming pics and wiring I think I can tackle it but I orders some stuff already and Im sure I will have to lay it all out and order more or swap some unneeded stuff out with summit, they are pretty good about returns and trades. Thanks for all the help I will report when I get it all figured out.



The dealers sure don't make much on the kits not near as much as I thought



slight price diffrence ona say brass 1/4 to 1/4 90 and some of the 14 and 22 dollar aero trinkets!



If I was say poole I would sourse this stuff better and order big voulums and post a kit price allong side a list of our price for all the parts and lengths of hoses that it takes.



That way people would see that they are srewing up for not buying the kit.





Had a guy wanted brakes put on I told him 125 for his powerchoke. told him 65 for the pads and 1 hour at 60 to turn the rotors and install my price for the best pads at carquest was 33 or something making me almost 100% on the pads. What does he do leaves and brings back a grade lower pads from Napa for 68 and change cost him 128 in all and cost me 32 for not letting me supply the pads.



some men you just can't reach!

 

[Rman]

I know summit and Jegs don't do too bad on them either.

oh sorry man I want to get some dons'4s from you but not yet

already into my line kit wish I had waited on you! :{



wana help?



does the one that feeds the VP need to be a 120 or just a 90?

Is a upgraded return needed or just leave the hard line and banjo?





THANKS OLEE I will see you in the future...

 

[OPoole]

I have the mach 4s just let me know! Stock return is fine upgrade the feed lines and a 90 works great.

Anyone spending the time and money to upgrade the fuel lines might as well do -8AN, don't bother with -6AN. Reason being if you measure the ID on -6AN fittings you only have 1/4" which doesn't really give you any improvement over stock. The min. ID I've seen on -8AN fittings is 3/8" and that's a sizeable jump in cross section.

The -8's really are amazing. I have a comp and stock LP, with mach 2 injectors, and I see hardly any pressure drop. Long grades will pull it to 12-13 psi. Almost always holds steady at 14. I've been happy after doing mine, lot of work but worth it.

My thoughts exactly... ... ... ... ... ... .

 

[rivercat]

don't get me wrong RD I can make pretty welds with the right gas and wire but my friends are set up with hot 95-5o2gas and 45 wire for sloppy high production well not sloppy on heavy stuff but sloppy on thin pipe. just think that stacks should be done by tig for cosmetic greatness.



no twins just jerking your chain

Vaughn,

To be truth full here the ID of a -AN6 fitting is . 265 (slightly over 1/4") and the first 3 banjo eye ports from the LP to the filter are . 170 (slightly under 3/16ths). Couple the upgrade of . 265 ID from OEM . 170 with all straight fittings (no hard right angle banjos) and 90 degree "sweep" fittings for your turns and I would say you have made one HELL of an improvement on fuel flow for a truck that will see a moderate amount of modifications.

There's volume, and then there's VOLUME!

measure up the -8 an's I. D.

 

[GHill]

How are you guys gettings from the 12mm x 1. 5 on the injection pump and filter housing directly to -8an?
