Will a Kenndy Lift Pump Be Ok Sucking?

[TRUBBS]

Just purchased a Kennedy LP setup from a member on here, I want to do a sump/filter setup when I install it.
I want/plan to run a 30 micron water separator/filter before the pumps & a 2 mic after, followed by deleting the stocker up top (unless you guys convince me it's a bad idea)
My question is, will the Kennedy's live a long & happy life pulling through the 30?

I have a sump I will sell you, no tank drop setup

Might be interested, price depending.
post your price or Pm if you want.

I think I'd set all of it up down stream of the lift pumps. and getting rid of the stocker is a good idea.

Not trying to argue or sound like a know it all by no means so please don't take it like I am but...
My main reason for wanting the one before the pumps was that's how the 7.3 PSD world has been running them forever & how I set mine up on my old 7.3 so it was just my natural thought to do it that way.
I liked having the big piece filter & water sep before the pump to try & protect it from anything that might get into the fuel somehow.

Why not call John and ask him? IMHO run both filters after the pump, if you run a large water separator before the filter you will need to bleed it every time, those Kennedy pumps won't pull air through a filter and bleed that way. Plus those pumps don't have many wear parts so a little debris from the tank won't kill a pump $.02

That's the info I was looking for. Thanks.
I'll just run em both after the pump

i'd go smaller than 30, go 10 to 2, most diesel dispensers have 30's on them

ill look into it and see what i can find, i think i still have the P/N for a 12mic water sep so ill probably go 12 then 2.

I want it if you still have it.
If you do, PM me your paypal info.

Wish I seen this earlier! I had Kennedy's pumps. I pushed and pulled thru a Cat 2 Micron filter in the middle of the pumps with no issues!

You don't want to go smaller pre pump there is no point. It would just restrict the fuel after the pump fine filters are fine. Pre pump you just want something that will protect the pump from trash.


I wouldn't wast my time unless you are getting fuel from private tanks. Fuel stations all have filters. I asked Kennedy about this and he never got back to me. Since I had rust in my tank when dropped to install the pickup. I just quit fuel up on transfer tank without filters.

If you pump out of a diesel dispenser at 30 why would you want another 30 on your truck?

It has very little to do with the micron and more to do with the gph of the filter.

 

[malibu795]

most big truck 2 mic filters Bf7587/1r-0750 have a flow rate of 12-15GPM or 720-900gph

i dont think "filter flow" is going to be an issue seeing that 90% of us run less than a 200gph lift pump

If you look on his website you'll see that he puts the filter between his two pumps; that should give you a good place to start.

I have dual kennedy pumps on my pickup with no filter and they've worked great since I first put them on. I use my stock filter as my first one then his mega filter after than; I also have a magnet on the mega filter.

I'm happy with my setup and haven't had any issues.

Exactly my point why put any filter pre pump when it has been filtered? Especially and more restrictive one that might limit power?

X2. Put the filters after. Pumps will work better.
