Fuel pump on my 280Z is bad. I might turbo the car later on so I’m thinking about getting a Walbro GLS392 255LPH since it’s the same price as the stock replacement. Are there any other external aftermarket pumps I should consider? Maybe something more challenge budget friendly? Quiet would be nice too.

I'm using the "front" (high pressure) pump from a 1/2 ton Ford van on my RN Truck.

Any external pump from an rwd Volvo will produce more fuel and pressure than you can use- plus if you are modifying things, it can be found as a package with the fuel filter mounted as well.

I have a 7 bar fuel pressure guage that was ruined by a stuck pressure regulator once.

Funny, I remember you telling me that exact same thing when I was looking for such a pump.

I'm sure I have one kicking around the garage too.

Sooo...could this provide enough fuel for say, a turbo Miata?

OP, I have no personal experience with Walbro 255's, but I have heard anecdotes that they are LOUD.

I have a Walbro 255 in-tank pump in my 96 SS. I can tell its louder, but that means if I listen really hard when I turn the key on, I think I can hear it. Externally, I have no idea.

I'm planning on using an Aeromotive A1000 for a 650 LS1 build I'm dreaming. I hear that THOSE are loud.

Could you suggest a model/year?. I have a home brew turbo project that needs an affordable high pressure pump,the injectors are going to be a little undersize and I need to crutch them with more pressure.I know its ghetto but hey this is grassroots motorsports after all right?.

I'm starting to think the walbro 255 might be overkill for what I need. The Ford or Volvo pump should work as my power goals are 250-300hp. As for how they all flow here is what I've found while searching: (some numbers have been rounded)

Walbro 255LPH / 67GPH

Walbro 190 LPH / 50 GPH

Volvo pump 155 LPH / 40 GPH

Ford E-2000 155 LPH /40 GPH

Stock pump 115LPH /30 GPH

If these numbers are wrong please let me know.

Any 200 or 700 or 900 series car with Bosch fuel injection built between 1979 and the end of production. When you go to the wrecker, bring the fuel fittings and electrical connectors.

I found that my E2000 was running out of volume on our ZX10R engine. That surprised me. A new Bosch 044 pump solved the issue.

Yea, not sure if it was that particular one or what--but it really couldn't keep up with the ZX10R on the dyno. We were tracking fuel pressure vs RPM and it slowly dropped off over the course of the pull.

I'm looking at a pump from a 760 turbo for $129 from FCP and $106 on amazon but I can't seem to find the pressure/volume specs of the pump,anyone know?.

Found a few more universal external fuel pumps. Airtex is a common brand that most local parts stores sell which might be handy if you need a replacement quickly. They even come with mounting brackets and fittings

E8248 265LHP / 70 GPH 3/8 hose 120 psi

E8228 144 LHP / 38 GPH 5/16 hose 120 psi

E8445 133LPH / 35 GPH 5/16 hose 65 psi

My local Advance actually stocks the E8248. With one of their discount codes it’s cheaper then the Walbro.

Finally picked a fuel pump. I ended up going with an Airtex E2182 which flows 190 LPH / 50 GPH and has a 1/2" inlet and 5/16 outlet just like my stock pump. Cheapest I found it was at Rockauto on closeout for about $50 shipped incase anyone else is looking for one.

Many car fuel pumps will outflow the regulation capabilities of the bike FPR. So you get high pressure on low flow conditions (idle up to some injector flow rate) then rail pressure is dependent on how much fuel is purged off by the injectors i.e. pressure goes down as injector duty cycle increases. If the pump can build enough pressure they can blow the regulator diaphragm out and then you have a real problem.

Any external pump from a car with CIS will provide plenty.

When you're at the friendly local Pick and Pull, look for VW, BMW, Saab, Volvo, Audi, Mercedes, Porsche and any other Euros I forgot from basically the late 70s through the later part of the 80s. If it has CIS and an external pump, you're all set.
