Could a guy add a extra lift pump in frame like the already in tank one or the filter one to aid your stock existing pump? even if it dont come with filters and filter pad? can you pump through a lift pump with a lift pump?

You can't pull through a non working pump. Most aftermarket pump mount on the frame. Do a search on fuel systems. You'll find hours of reading.

i read lots. i was looking at the glacier walbro 392 and since my truck is a 2004.5 i looked tha one up. it says for filter mounted lift pumps only. my truck has a rear or in tank pump. (because i turn key forward and hear loud buzzing coming from rear) Im not 100% positive if there is 1 in my frame rail underneath but im sure its in tank. So do i order the 2005-2007 dodge ones then? Because the 2003-2004.5 ones say FILTER PAD MOUNT ONLY?

what about this pump? PPE Adjustable Lift Pump for $250

also can u get filters for the fass or airdog in canada? can they be referenced up to wix or baldwin or would u need to get airdogg or fass filters for them $700 units?

first make sure you know where your stock pump is........... my two picks for just pumps would be the new raptor with built in regulator(what a cool idea)
or walbro either one is a great choice...

Here's a thread that shows the two Holleys I have hanging under my frame. The problem was (as reference in an above post) when the stock lift pump went out, I couldn't push more than 1/2 psi thru it if at all. Here's the solution.

I made an adapter to take the place of the stock lift pump and then the full volumne and pressure was no problem. I was able to keep the stock filter cannister with the heater, water seperator and the fittings too.

has the link to the pdf doc that has the drawings for the plate so you can check your bolt pattern and see if it'll fit.

Some aftermarket lift pumps aren't draw-through on failure/de-energization like the OEM in-tank unit is... not much of a reason to replace the in-tank LP unless you're pushing a LOT of fuel into the rail. (they're pumping more fuel and proving to be far more reliable than the previous filter-mounted POS)
