Engine/Transmission (1998.5 - 2002) Help with fuel delivery please.

[Truckie]

I need some fuel delivery help. I'm sorry about it being brought so many different ways, but what is a good quick easy fairly inexpensive way to help get fuel to the lift pump. I don't want to spend a fortune right now because of some other mods I have going on now and are getting. I do eventually plan on getting a FASS system but it just isn't in the cards right now because of some other stuff I got going on now.

Thanks

MIKE

Wildcat maxflo fuel lines and fittings.

It did the trick for me. Under $150. I was sucking my pressure down below 0. After fuel lines and drag comp upgrade I can't pull it below 5. I know this is too low but I'm also slightly over 500hp. I would guestimate the lines alone will be good for 450hp all day long. As for me, I'll be looking at the FASS before long!!

You can also get the needed parts to mount your OEM LP on the frame rail by the tank for under $70. 3/8 or 1/2 fuel line, Webber fittings and some hose clamps. Pick up a LP pigtail at Cummins and a joist hanger at Home Depot. The RMTDR is going to be doing a LP relocation day in January, and there is a shop in Denver that is making a package with all the needed parts. Check in the Local Chapter section - Central - Colorado for more info.

Hey truckie, I'll be moving to Cincinnati in a week, not to horribly far for you. If you ever make it down my way I can show you the setup sticks is talking about. My truck was the experiment. I did it for about $50 if I remember right. I am suppose to take some pics before I leave so these guys have some photos to work from for their Jan 3rd wrench day.

I agree 110%, best thing you can do right now is one of the cheapest mods. Move that pump back by the tank and replace all inbound banjo fittings with Webers. Don't forget the line that runs from the fuel filter to the VP44, very important IMHO. You can get rubber fuel line from Summit Racing if you don't want the expense of the braided ss line. Make sure you keep all lines very secure, especially if you use the anodized hose ends. They don't like vibration much, trust me on this .



If you don't want to bother with all that, pick up a short length of braided ss line, 2 Webers and 2 90 degree hose ends. Use that to replace the line bewteen the filter and the VP44. It won't help your lift pump but you will get a better flow to the injection pump.

Big saint could you give me a little more info on the setup you are talking about. I don't want to move my lift pump because it gets real cold up here in ND but would like to make a inexpensive set up like you are talking about what would i need to upgrade my fuel system with the lift pump in its current location?Thanks for any info you can offer.

Unless your running the big HP numbers... a simple relocate is my personal favorite fix when using the factory lift pump. Just my opinion. I dont think bigger lines will do you much better either. The stock lines are, or are close to a full 3/8" thin wall stainless tubing.



Your more than welcome to read all that I've posted on the subject. Inside this link is another link about exactly what I did. If nothing more it might give you some ideas for your own setup. My various photo albums also show alot on what I did personally.

It's not so much the line, as it is those darn banjo fittings. The best thing to do is use straight through fittings. If it were possible to get away with out using and 90* elbows I would be ecstatic.

Jarrod, the easy fix for more fuel flow to the injection pump is to simply remove the banjo bolts at the outllet(bottom) of the fuel filter housing and at the inlet of the injection pump. The Weber fittings screw into the bottom of the filter housing and the inlet of the VP44. They have -6AN fittings on the other ends to which you attach 90 degree hose ends and braided ss fuel line. This completely does away with the banjo bolt strangle hold on the fuel delivery after it leaves the fuel filter. It will do nothing for your lift pump.



I agree with Ncostello on the lines as well. 3/8" inbound is enough for most, including me.



This is a Weber fitting... 12mmX1. 5 thread

Sticks... it is possible to get rid of angled fittings including banjos. The only elbow fitting I have is at the VP44. Its a steel Aeroquip 90 degree elbow. I could have went with a 45 or even a straight there too if I really wanted. The only other angle is at the top of the tank... which is the factory elbow.



All other fittings (6 total) are straight through... and it does make a difference. I cruise with over 15psi and not pull it below 14 with the stock system gone. This is with the stock Carter pump.



I felt the most restrictive part of the stock system was the line between the OEM filter and VP44. It has that 5/32" short hose section and the hard line looks even smaller. The banjos on that line are miniature also.
