    Lots of people running the carter 4070, holds a constant 5 psi in my truck no lack of flow issues either with 90cc and stage 1 injectors. Mechincal pump even new would drop pressure when revving the motor, with this pump no pressure drop

    I'm going to guess that if the diaphragm fails, it can pump fuel into the crank case?

    Yeah mostly the diaphragm issue. Exceedingly rare I'm sure, but don't think a properly sized electric could ever kill an engine, ha.

    A thought to ponder....A mechanical pump with a ruptured diaphragm would tend to starve the ip for fuel, giving ya a chance to check why it died????
    I realize the truck could still run.

    I have heard Carter outsourced their P4070. I have an earlier one, about 5 rears old, runs fine, but the electrical connector is a lot flimsier than I expect on automotive electrical stuff.

    I have heard good stuff about the wallbro frb13-2.

    https://www.fisheriessupply.com/wal...sure-limited-reciprocating-fuel-pump-frb-13-2

    When it comes to stuff like this, reliability ranks damn high in my list. These aren't cheap. But if it was designed to survive life in a boat.....with saltwater and a bilge environment, I don't think I can throw anything worse at it.

    Those marine walboro unit seem solid. And still cheap compared to aftermarket alternatives. Some of the pricier setups are $1000+

    Subscribed to learn. I really want to do this to Raylan so that I'm not terrified of inadvertently running a tank empty. Eventually going to drop the tanks and refresh the shower heads, but even then I'd prefer not to be sucking air with the stock pump. If I were able to run a ZF5 I be hesitant to add electric components, but since my bum hip has reluctantly turned me in to a e4od guy, well, in for a penny, in for a pound...

    well , for me, I run a facet pump, as close to the dual tank valve as I can. on my idi. n/a.. worked great for 2 or 3 years with clean diesel. but running waste transmission fluid was good, until it got cold.. ( I can understand that,, flow rate when cold and all,). but now with a turbo set up.( big thanks to thewespaul and russ, ) I have turned up the ip 2.. 2.5 flats, and have noticed a rolling surge going up long hills (even full tank on clean diesel..) some smoke , egts are 800. 825. and 3" straight pipe . the only change from last year , is the turbo set up , 1 more flat on the i.p. and muffler removal. I belive im running out of fuel... filters are clean, no load, no "fuel filter " light, but its something I have to fix... so, im looking into a higher flow rate pump. this is just what I was looking for. thank you...

    I say do whatever you want lift pump-wise, but the terror isn't a bad thing. Mine runs on only thee front tank and I can run it down far enough to put 17.5 gallons in it so I know that the shower head in fine, but on trips more than about 40 miles or so from home, I'll still fill up at the half tank mark just to be safe. Especially in the rural areas that I usually drive through where it may be 40 miles or more to the next place to get fuel. Night time is even worse. Most of the small towns have a gas station, but they'll close up at 10 PM or even earlier and my debit card won't work at all of them. I just plan to fill up between 120-150 miles and I'll be fine.

    Yup don't even try the Carter rotary vanes anymore, like the 4070. They are now pure JUNK. I have 7 dead ones on the shelf, all have less then 500hrs on them. Whereas they used to last 5000+ hours in the same mounting locations.
    I have switched to Walbro FRB-13. So far, no problems. Lots of flow, pressure drops to about 2 psi on wide open throttle but usualy hovers in the 5-6 psi range....when mounted on the frame rail with a see thru filter ahead of it.

    The Walbro's are a little tougher to locate and purchase but if they prove to have good longevity, I don't care. Reliability is key for my purposes

    Thanks for the info, how long/how many hours do you have on the Walbro?
