Fuel Pump Frustration

[mini14]

radios1 is correct, its 1/4 pump, it should do the trick, there should be a small fuel filter installed b4 fuel enters the pump like a baldwin bf840 if u got foam its not the pump doing it, your sucking air

OP is your fuel filter before or after the pump? If it's before there is no need for the addition of a small pain in the neck filter that will need replacing..

Radio, that's 5-9 psi.. if the 4-7 is "to much" fuel, the poster isnt doing any better..
Sounds like a 1-3 psi is in order here.??
I have 1 I took off a diesel motor that a customer bought, but I have no idea where it is.. sorry

The fuel filter is before the pump

Thought about it more, and its probably not the pressure that is making it foam, its the volume. The lift pump feeding the injection pump doesn't need high volume, and all the diesel is mainly going back to the tank, so your filtering a lot of fuel.

Might look for a electric pump for a tractor or mower of similar size. Don't know if this would fit the bill but here is one for a BX1860 so 18hp 3cyl diesel

That one looks more like mine. Thanks

this one has threaded fittings, just get an adapter for the size you need. https://www.amazon.com/dp/B07CKS4CHH/ref=psdc_15728151_t3_B07JPDZC4M

NAPA has one like that. They did not have a fitting though, couldn't get on either, although it could have just been a lazy clerk

you can try a hardware store or plumbing supply. it's not the pressure or gpm making it foam, btw, it's air getting in the inlet of the pump. you will get some from a newly installed pump..

What make is the engine? If Daedong you might try a KIOTI Dealer.

my ventrac 4500Z is back to dying after 30 minutes running the PTO, fist time I changed filter and found the vent line was plugged...it worked good for awhile...now its doing same thing again...this time I am going to change the electric fuel pump. Does anyone how I can cross reference this part number out on web (8J01 B76) that is what is on the pump itself, ventrac has a different # in the manual, I was hoping to find one out on web somewhere and not have to pay ventrac over 200 buck for one

If u can post a pic of the injection pump, I can tell u what pressure it runs at..
More than likely u have a PFR pump.. the ones that have an external cam shaft and sit down into it’s own little spot in the engine..??
If so, they run no more than 10 psi..
I hope this helps..
