I used the non-metal standoff spacer to mount pump motor to bracket to clear the brake lines & wiring (very solid). As a side benefit, I think it helps deaden some of the sound transmitted to frame.

Although with that said, I can definetly hear the pump engage when the key is advanced before start. A very reassuring sound though! When it is running I can hear a slight whir if I listen for it. However, I find that a good sound as well. If you are really concerned about ultra-quietness it would'nt be that hard to put some kind of material on both contact sides of the bracket that sandwich the frame. Maybe some type of compressed hard rubber material, not too thick though as you need room to slip the bracket under the existing brake/fuel lines that run inside the frame. By the way, I did have to temporarily take off my skid plate (4 bolts) and ended up mounting pump just behind my 48RE transmission's transfer case. I have a short bed and vacant frame rail space is at a premium! That dang OEM frame fixturing bracket thingy was on my frame and blocked the recommended location. That bracket would be extremely difficult to remove (cut-n-grind) without taking the bed off.

Thanks for the info, once I get in the mail, I will see how much room I have to slip some kind of rubber in there

Thanks again to all for the help

Stock filter cap will hold to +-30lbs, not really sure why Richard stopped dealing with Walbro, mine has been trouble free, purchased a spare from pumpsusa for $107 just the same.

I have the FASS pump without the air crap. It puts out 23 psi and I haven't had any problems with the stock filter cap. Uses the stock return line. Works fine for me.

Just finshed mk-2 install and raptor 100, both products are great and easy install, had some concern about pump noise, so I cut a inner tube to wrap around the frame and then installed the pump bracket, very quiet and no metal to metal contact to transmit vibration, could not be happier. thanks to all for th info.

My walbro has been on since 2008 running 21psi. Never a single problem.

Question about the seal, or gasket, on the fuel tank. Where, how much, and how difficult is it to replace? Here is the issue. I have a 48 gallon auxiliary tank in the bed, that gravity feeds my primary tank. Once the primary is full, it starts dumping fuel out of the top of the tank. I located the leak. It is coming from where, what appears to be the lift pump, goes into the tank. As long as the primary tank is not FULL, it doesn't leak. Any help would be appreciated. Thanks, Baron

I am in the market for a good lift pump and from what I have read, I like the Raptor. My question is which one do I need? I will be running it on my 03 with 70ish injectors and probably a Smarty JR. 100 or 150?

They say that the raptor 100 is good to about 550hp after that you would need a 150
