lift pump help

[catnhat]

I will check the pump screen and put the pump on a relay how do you do that what kind of relay,wire size and just over all how to do it. I am not very good with electrical stuff so make it very simple for me

If I get some free time tomorrow I will put together something in depth for you and how to accomplish it.

This cleared a lot of thing up for me if it correct I was thinking 12 or 14 gauge  wire with a four prong relay only thing I am not sure on is what size relay and the inline fuse should I use 

[Me78569]

Just use a standard auto rely, same as what you have under the hood.

 

Not sure on the fuse, I don't remember what my pump has.

[catnhat]

I just called them and they have a 15 amp or 20 amp relay 

[catnhat]

Little more advice from you guys got the relay all done not to bad. I had a 15 amp fuse in it blow that after a couple of seconds  so I put a 20 amp fuse in poped that one to. Now I  smell burnt wires have gone over all my connections multiple times and check the relay to make sure I had it in there right. All my connections are tight and with heat shrink on then. Starting to look like my pump is burned up any advice would be helpful

[Me78569]

do you have pressure before it blows a fuse? 

 

What wires do you have doing to what pins on the relay?

30 should be fused from battery, 87 should go to the airdog pos

86 should come from ecm positive leave 85 ground or negative lead from ecm

Yes it was at 15 and slowly falling. Battery is 30.   87 pos raptor.  86 yellow wire off the oem harness  85 grounded on firewall  I did ground the negative on the Raptor and never did anything with the ground on the oem plug 

[Me78569]

that's fine.

 

Yes your raptor has bit the dust.  It is a good thing you got it pulled off the ECM power.   If you try to keep running the pump I would expect issues with wires burning up.  

 

your issue is that the seals inside the raptor have failed ( like they are known for, I went through 5 pumps in 1.5 years)  this is causing the pump to draw a buttload of amps trying to keep up.

[catnhat]

Well dam at least I don't think I messed anything up and that it failed only 2 blocks from my house . This pump is about 3 years old never had problems tell now.do you have any recommendations on what pump I should get next 

[Me78569]

Fass 100 or 150 whatever the budget will allow for.  

 

I have a VERY bad taste from airdog stuff.  

[catnhat]

I will be looking in the pumps soon thanks for your help with everything

Recheck your wiring too You don't want to chance burning any new wiring. I'm glad you are getting this figured out with others as I'm commuting a total of 3 hours a day plus putting in the usual 8 hrs.

 

One very important thing about fuses. If one blows don't go changing the fuse size because then your wiring becomes the fuse and that's expensive/ time consuming to change out.

[catnhat]

I think I spent more time checking the wiring then it took me to put it in.thats why I stopped at a 20 amp fuse you would think a 15 would hold it . I plan on checking it again when I get off work today. As for a new pump does the fass 150 come with all new fuel lines or does it connect to the stock ones. It doesn't  say anything about running new lines in the description

yes the FASS comes with everything needed to install. Fuel lines, fittings, mounting bracket and electrical

Get a FUEL BOSS. No wires, no fuse, no relay, just FUEL PRESSURE.

I haven't had any issues with my fuel boss.  Constant STEADY pressure.

[catnhat]

They are about the same price I am guessing that the fuel boss comes with all new fuel lines to

Not all new fuel lines.  If I remember right, mine came with new that connected to the hard line coming from the tank under the driver's floor board.  From there it splits and goes to the stock pump (if it located on the block) and to the Fuel Boss.  From the fuel boss to the filter housing.  I opted to buy and install the Big Line kit form GDP so that improved the line leaving the filter housing and going to the IP. 

It does come with enough 3/8" fuel line to go from the pressure regulator (that you install) back to the filler neck at the tank (you will have to install a T to allow for this return, all of this is included with the tank). 

[IBMobile]

It comes with all the hose and hardware you'll need and installs in 2-3 hours depending on if you put in a back up lift pump for priming and starting or not. I have an Airtex fuel pump in line but have it unplugged when I found that I don't need it for start ups. This link will give you the install instructions for the Fuel Boss.     http://www.glacierdieselpower.com/images/PDFs/98.5-02-Fuel-Boss-Install-Manual.pdfoss
