Secret NAPA fuel pump part # found!

So I just want to confirm something that is a bit cloudy. I have a 1991 2.2 Subaru engine in my '85 vanagon. I know that fuel injection units are very picky about what psi they receive from the fuel pump. The original Subaru fuel pump was in-tank and rated at 36 psi. It sounds like the majority of folks have liked the Bosch 69414 pump for a replacement. Will that pump be compatible with my Suabru engine or do I need to obtain a different pump? My beef is when you look at a pump for sale on EBAy or Amazon, they do not provide any spec info regarding psi or gph rating.

Generally, fuel pumps put out plenty of PSI. Fuel Pressure Regulators reduce the pressure to that needed by the injectors and related distribution system which is quite a bit lower than pump pressure. For an external pump like the WBX uses, the type of fuel pump installed can be a wide range because they'll all "fit" the location.

This may not be true of an in tank pump as you describe, which requires a certain shape for the mounts and such.

So I would be inclined to experiment with a WBX external pump setup, but definitely would buy the precise pump for an in tank pump. But if you are asking about an external type, I say go for it.

I was just recently thinking about buying a spare pump for my Vanagon and installing it on my Quattro for a while to see if an occasional loss of power is a fuel pump on its last legs. Like the Vanagon, the Quattro is an external type. Mentioning that to show the plug n play aspect of many fuel pumps.

hi Doug

i did (quickly; noted) receive what appears to be a "Bosch" 69414 pump:

i don't know SfromS about subi swaps, but this pump is very capable of pressures higher than 30-40psi.

Looks good, but for the $ conscience any of these FORD E2000 fuel pumps will provide plenty of gas under plenty of pressure for our engines.
note that you want an inlet/outlet to match yours for ease of install.

Probably mentioned elsewhere, but nearly every time I have encountered a noisy fuel pump it had nothing to do with the fuel pump. It was caused by blockage AHEAD OF THE FUEL PUMP. Early tanks have nylon filter sock in them. EVERY old Vanagon tank I ever owned had a rusty tank and plugged this filter. Also, fuel pumps have a mesh screen at the inlet fitting that will plug up with larger debris.
I would never , ever run a pump without an inlet filter or this screen will be plugged. I think the nylon mesh in the tank often gets torn, so it is the worst of both worlds (plugs up AND does not filter.). Very often a temporary cure to noisy pump is to unhook the hose coming into the engine bay the one from the pump and blow air backwards thru it. Air over about 50psi will escape past the bypass of the pump and clean of any clogged mesh temporarily.
I immediately install a Napa 2032 filter head of the pump Between the tank and the pump.
If this plugs on the road, one can remove it and back flush it with any spray can solvent with a straw, like carb cleaner or WD-40. Backflush it onto a white paper and a nice pile of rust will be on your white paper. Maybe not as good as a new filter , but way better than walking to buy one.

Bus Depot is selling a pump that they identify as a 043906091 without giving the brand name (that I saw at least), but do say it is US made. Am interested in a pump that I can get from a chain autoparts like O'reilly's or Autozone so it would be easy to replace under warranty out on the road. Does anyone have info on the 043906091 pump. Any recommendations on other pumps to buy which would be commonly found at a chain auto parts?

Thanks

I love my local NAPA. I was very loyal to the larger "Vanagon" suppliers, but gave up on them after dealing with bad attitudes and long waits for parts. Most Vanagon mechanical/tune up parts are not stocked in my local store, but are ordered from the warehouse and delivered to my office the next day. The parts are identical to what I can get online and are delivered for free. I am provided a better service while supporting a member of my local community and I am still able to support the vendors I consider to be the Vanagon specialty supplies when I order the spare tire mount for the bumpers I installed a few years ago.
