How to replace lift pump

Hey guys, I am going to replace the fuel lift pump on my truck within the next few weeks. I am wondering first of all where the lift pump is on the engine. Secondly I am wondering what tools I will need to do the fix. Thirdly I need to know where I can get a good fuel pump. I assume I will need a bosch?

And last but not least I need to find out how to actually do the fix.

Thanks in advance,

Steve

The lift pump is on the front passenger-side lower corner of the block, same place where Chevy engines have them. You can get a pump from a parts store, or order on online, either way it should be about $35. Tools you will need - 3/8"-drive ratchet, some extensions, and 1/2" or 9/16" sockets, also for the fuel lines you'll need some open-end wrenches (I'd think 9/16" or 5/8") for the steel line and also a screwdriver for the shot hose between the frame and the pump.

Napa, Carquest. This type of fuel pump is hard to make a bad one.

My dad just bought the pump for $150, I thought that was a little high. The guy said thatr it was new... and that the $40 ones were rebuilt. Is it high?

I got mine for around $40. I would take the $150 one back. Mine came with a 1 year warranty, but I expect it will last a lot longer than that. Make sure you get the arm on the right side of the camshaft, you can bump the starter to find the sweet spot. I never did find the so called sweet spot, it takes a fair amount of patience. I recommend you remove the alternator to give yourself an easier shot at it from above.

This is the pump required........or a crossover brand..... visit my photo link for pics of old and new..

This info pertains to Carter #M60278 pump or new long arm style.

WARNING

This fuel pump must be installed only at the low position of actuator cam.

If the pump is installed at any other position than low cam, the pump will be ruined, the engine will stall and damage may result.

Incorrect installation will loosen the pivot pin and allows the pin and lever to come out of the pump and drop into the oil pan. This can occur immediately or after several hundred miles. This type of failure is not covered by warranty.

To ensure that the cam is at low position, it is necessary to use a mirror and a remote starter switch. Observe the cam through the mounting port and bump the engine around until a one (1) inch wide machine surface is observed. This is low position of the cam. Now complete normal fuel pump installation.

Rockauto.com has AC/Delco's on closeout sale for $19.95 plus about $9.00 shipping. I got one and it worked good.

As far as I know those pumps cannot be rebuilt, you can't take them apart once put together, they are swedged together. Take that 150 pump back and get one of the 40 pumps, they will last a lifetime . If they could be rebuilt , they would ask for a core.

the $150 pump was the wrong one... the guy on the phone didn't know what he was talking about. We got one from napa for $33 and put it in yesterday, it works nicely now. We also replaced the tranny cooler. Now all we need to do is drop the tank and and fix the pickup valve so we don't get stranded in the middle of the woods having ran out of fuel with half a tank of fuel still there!

For what its worth I bought and Air Dog II 165 last year for my 2005 6.0. I was a tough choice with many here on the forum not flattering to Air Dog's quality.

After less than 8,000 miles the electric motor on the Air Dog pump went out. I called Air Dog as it had a lifetime warrantee. They "couldn't find" the warrantee card I sent so I faxed them my reciept from Sinister Diesel for proof of purchase on the unit.

I was told that a receipt was not good enough and they charged me $218 for a new electric motor for the Lift Pump. I'll send in the warantee card on this one "Return Receipt Requested".

I would advise anyone purchasing an Air Dog Lift Pump to send in the card, and then CALL Air Dog and make sure they got it, get the persons name you talk to and the date of the call... The Air Dog works great...until it doesn't work, and then in my case their not all that receptive to customer satisfaction.

I don't know if the Air Dog is any better or worse than other Lift Pumps. I bought mine because of the Lifetime Warantee and I should have practiced CYA better and got confirmation of their reciept of my warantee card. Oh well, be careful..

BYT the Sinister sold me my Air Dog II #165 for $662.00 but I bought over $3000 worth of "get the 6.0 back on the road" parts. Good Company ease to work with when I emailed them about the problem I was having the spoke to Air Dog on my behalf. Air Dog was not receptive. Sinister even though it was no fault of theirs sent me a $100.00 gift certificate because it was a product I purchased through them... now that is customer service. Big difference in companies out there. Businesses forget that just because your on top today, doesn't mean you'll stay there if your unhelpful to your customers.

If you can still get a seal without having to smash the olives, then I would re-use them.

I didn't replace mine 4 years ago when I changed my lift pump. I started the truck and looked at the fittings. If it was gonna leak, it would have then. Still golden.
