Fuel System

[boredandstroked]

What type of mods are being done to the fuel system. I need to replace some lines and was thinking maybe some upgrades should be in order. This is a 97 F250. Is there a line kit avaliable? How many have done the super duty pump upgrade? is it worth it? Fuel Bowl Delete? Whats the scoop for the OBS. Or can any body just recommend a good line to replace the factory stuff in the valley with. Thanks for any and all input.

I have done an E-fuel system for my '96 a while back. Used an SD electric pump, pre-pump spin on water seperator filter and a post pump 2 micron Cat filter. Used the stock steel lines to the heads and aeromotive regulator. Really liked the results smoother power and all way to Redline pulled much harder. I am in the process of piecing together a system for truck in my sig right now only using a 6.0 litre e-fuel pump. This pump has a filter, water seperator and heater in it all in one unit. thinking I will put in a pre-pump filter 20 micron/water seperator spin on and a post pump Cat 2 micron filter too. Using the stock fuel lines as I did on my '96. For info do a search here also TomS on powerstroke nation has a really good write up....

I have the lift pump leak in the valley of the motor and if i converted it over to the e pump i wouldn't have to replace that lift pump right? Also anyone have an idea how to do the fuel bowl delete on these obs trucks?

There are a few aftermarket systems (Airdog), and some of the vendors have put together efuel kits. Beans & Dieselsite have systems that look pretty good, but they are a bit pricey!

using the stock fuel lines...the most expensive cost is the pump and the regulator.
Cant rember all the parts and fittings, but.....I using a Mallory 5110 pump, 10 micron filter, 15 micron fws from wix. The fp is replaced with a freeze plug. Gonna have to fab a brkt for the regulator. Need the correct fittings for the back of the heads to connect the fuel lines to. Yea, its worth it!

Probably gonna swap over to 2 walbro pumps within the next 6 months.....130(?) each. If 1 fails, the 2nd will supply enough fuel to drive the truck. I would recomend a fuel PIS gauge on each pump, so you know there both working.

Im in the process of building mine. I have a SD pump a 12mic prefilter ind a 5 micron post filter from NAPA and the filters are both about 8" tall. I am running all new 3/8" hard line from the switch valve up. I got all the fittings on the heads converted to -6AN with custom bent hard lines. Then I have braided flex AN lines from the engine to the frame. Ive been building it for about 2 weeks and I have a lot in it but thats because I couldnt just buy a pre built kit.
I really like the idea of the 6.0 pump.

The 6.0 pump I have has fuel heater (not all have a heater so check if you need it), water sensor. Also mine has a bypass valve that routes return fuel back into the feed stream if fuel is too cold, rather then back to tank. Not sure if all have this feature but for me I see an advantage perhaps, as I live in a cool climate in winter....

I think for the minimal additional cost I will put pre pump water seperator/filter say 20-30 micron and a post one probably Cat 1R-0750 both will be spin ons...

I wonder how to tell the difference between pumps with and without the heater? do you have the PN for your pump by chance? I may upgrade to that if I cannot find a decent heater for my system.

Hey Thad,
I will have a look at it to find the part number for you. In rooting about at my favorite auto junk yard for the electic plugs (as they are specific square waterproof ones) some of the wiring harnesses have only two plugs as opposted to three like mine. It appeared that the later 6.0 do not have the heater in them as I saw 2005 that did not have one. Perhaps ask the guys in the 6.0 forums they should know...

On my '96 I installed an inline fuel heater with the e-fuel system but never hooked it up, does it get that cool in Ohio? I can get you the name of product I had used, sorry, just can't remember off top o' the head..... it was a product used in Biodiesel applications....
