Lift Pumps That are Filtered

[RustyTRanch]

Has anyone added a second filter before the lift pump or pusher/lift combo?



What results have you had?



I would think dirt would effect these little pumps greatly.



I am going to replace lift and when I do I was thinking of installing

Filter/pusher/lift!



Pump pressure at 9-10 idle, 8 cruising. 4-5 wot



Comment or thoughts?



thanks

I think it's a great idea, I would still want a filter after the lift pump though just in case the lift pump desides to spit parts.



I don't know how much volume or pressure if any would be lost to a two filter set up but it would be interesting to see. maybe someone has done this with out a pusher pump and will inform us.

I had a 10mic filter inline before my first 2 lift pumps and they both went out.

90% of my fuel comes out of a bulk tank on the farm and it also has a 10mic on it.

Besides the stock filter which is after the pump my fuel was filterd 2 times ahead of the stock lift pump and the carter I tried after that.

Now on a stock # pump and seems ok.

Filters are a good idea as long as you change them often. Otherwise you could starve the pump.

I've been running a Earl's screen type filter, pre-Mallory pump, since the first 4150 died. It's rated to filter down to 35 microns and I do see some debris in it when I remove same for a cleaning. Not sure how much it's helping the pump as I am on my 3rd Mallory now. As long as you choose a pre-filter that has a good flow rate, can't see how it will hurt anything. The Earl's is rated for 5-6 GPM, more than enough flow. I clean it every 5000 miles with brake clean.

I would think it would be an excellent idea to put one behind the pusher pumps you poor 24v lift pump killers are having to install All of the aftermarket lift pumps through NAPA (carter brand) recomend running a filter before the pump to keep it from sucking trash and taking a dump.
