    Hey guys I got a new to me d150. I've done a little maintenance but now it's time to replace the fuel pump. Anybody have any tricks to remove the tank fill and vent lines or the quick connect to the pump it's self. Thanks.

    does the pump itself still work? if so just leave it alone. the stock ones are just as good if not better than any aftermarket one out there. if it is bad then there is really nothing to dropping the tank on a truck. just unbolt it and drop. you pull the plastic locks off the fuel lines and just twist back and forth off the sending unit.

    Yeah it's pretty much toast. ImageUploadedByTapatalk1447560634.377631.jpg
    It's this guy that I'm worried about. Then theirs a plastic connector on the hose behind it. I was thinking about busting the little nipples off the old pump then worrying about them after I get the tank out. And for the fill line just try to take it off at the tank?

    you are best to get the tank onto the ground and then pull them off. from my experience that connector does not look right for these vehicles. should be plastic connector connecting to the sending and i think the line to the frame is also suppose to be some sort of plastic or at least it is usually when stock

    Yeah it's probably a replacement line. I believe the connector behind it looks like that one.

    i wouldn't worry about it too much. if you drop the tank and can disconnect it at the other end so you can get the tank out it might make the line easier to remove from the sending when working on it while not under the truck especially if that is the type of connector i think it is. i think you will need tools like this to remove that connector if it is the type i think it might be and even then it is a real pain in the ass.

    also if you do damage that connector i don't think it is a big deal i am not 100% sure which one that is but i think they should have replacements and if all else fails you could probably get away with fuel line and hose clamps.

    Hey Crazy or any one really. I got the whole pump changed except this fitting. I broke it off the old pump just to speed things up and now I can't get it out to attach the hose to the new pump. I bought one of those tools you linked but the piece inside the fitting isn't perfectly round. Anyone got an idea or should I just rip the hose off the truck and replace it.

    i hate to say it but you may end up needing to replace the fitting. you could try drilling the plastic out but it will still most likely damage the seal.

    I just did this on my 1991 W150. I decided to NOT drop the tank because right before the pump went south, I filled the damn tank! Soo, I did the truck bed tilt way. Worked out very easy and was a breeze. Those connectors are easy to get off safely if you are careful if you have room. And you have plenty if you tilt the bed. If you want me to walk you thru the tilt bed how too, let me know here and I'll do it happily. But generally, there is a clip in the connector that is or used to be white plastic, it is probably yellowed by now. When you have the bed u-p and out of the way before you do anything else pinch the clip with a tiny slim needle nose plyer and just pull the hose straight off.

    Don't force anything and you'll get it.

    to tilt the bed simple remove the two bolts in the front of the bed, and the two center ones, halfway loosten the back two and then hook up a engine hoist to the fornt of the bed and simply tilt it up outta the way for safety use a couple jackstands under the bed between it and the rails and you'll have all the room you need. Here's a video on a 1996 but it is the same proceedure. Don't worry about the pressure deal he explains because the tbi trucks have low pressure.
