The Fuel System Thread: Stock to 1000+whp
Is there a write-up anywhere for Evo's on how to mount and wire up and in-line walbro, which fuel rails can have an aeromotive bolt to it, how to install new ss fuel lines, where and what fittings needed, etc?
I found one for 3000gt's / stealths but not for Evo's... trying to put together my own fuel system soon.

The Denso 1020 is a little different in physical size, which necessitates some minor modifications, while the Walbro is very close to stock size. People have been installing the Denso 1020 in DSMs for a decade, though, and the additional pump capacity and quiet operation are definite advantages, if you're willing to invest a small additional amount of time.

I'm very interested in the Denso 1020 Fuel Pump

Just need to see more of what would be involved.
The Denso fuel pump 195130-1020 (the Supra Turbo MKIV pump) is one of the best in-tank upgrade choices if you are using injectors up to 550 cc/min and are providing at least 13 volts to the pump. When 18 volts are supplied, the Supra pump is good for injectors up to 880 cc/min. At 13.5 supplied volts no other in-tank pump, except for the R33 Skyline GT-R and A'PEXi BNR32 fuel pumps, flows significantly more fuel up to 70 psi line pressure or 27 psi boost. It is a direct drop-in replacement; all other non-Denso choices require some modification to the fuel pump assembly. It is as quiet as the stock pump. Best of all, it can cost only $180 at Conicelli Toyota. One disadvantage of the Supra pump is its relatively heavy current draw (at 13.5 V, 16A @ 43 psi, 19A @ 70 psi) and large decrease in flow as supplied voltage lowers. Good, heavy-gauge wiring (meaning re-wiring the fuel pump electrical circuit) is a requirement to get the most out of this pump.
.
Mitsubishi Lancer EVO8 stock. This is a Denso fuel pump, model 195130-3360. It looks similar in size and design to the fuel pump used in the non-turbo 3000GT and Stealth. With a tested flow of 191 lph at 43 psi and 13.5 volts it could be considered a drop-in upgrade for the non-turbo models, but not for the turbo models.

Damn, I wish I would have seen this thread 6 months ago.
I'd like to talk to people that are using surge tanks in their solution. Currently I have 1 Aeromotive a1000 sucking off the back of the tanks. (Went the easy route, didn't pay off
)
A surge tank would be a good idea for upgrade #4. The surge tank will allow for inconsistancies in either pump. (Meaning that if one picks up air, the other won't.)
My thoughts are to use a 255 pump to feed the surge tank -> have the a1000 suck off the suge -> and have the return line feed back into the surge tank.

buschur has a walbro 255 that they sale that is modified and they say that it flows 50% more than a regular walbro 255. Does anyone know anything about it , do you think you could get it and a rail and be ok for a bigger turbo or is the fuel line to small.

Denso Fuel Pumps
Denso fuel pumps that have a 50-mm diameter and have part numbers that start with 195130 are direct "drop-in" replacements for the stock pump in all 3S turbo cars and 1st-generation DSM cars (1989-1994). Second-generation DSM cars (1995-1998) and all non-turbo 3S models use a 38-mm diameter Denso pump. My web page 2-fuelpumps.htm compares the turbo and non-turbo 3S fuel pump assemblies.
That's contradictive above^^^
Factory pump in the Lancer Evo8. Flow data from T&HTP.3
Design is like the 3000GT NA pump so an adapter would be
needed for the pickup tube and electrical connection on
TT models. An upgrade for NA cars.

CONCLUSION: THE SUPRA PUMP IS TO BIG TO USE WITH THE STOCK EVO FUEL PUMP HOUSING. IN ADDITION THE EVO PUMP HOUSING IS COMPLETLY DIFFERENT. LOOKS LIKE THE WAHLBRO WILL HAVE TO DO.

just a few things:
precision injectors (used by AMS, Buschur, us, etc...) are 275$ shipped or at least from me they are. Even AMS and Buschur sell them for less then 400$ as far as I know, way less, like low 300's.
The walbro in tank pump can easily be used to 500whp. I've seen many people doing that.
Stock injectors can be used to 400whp no problem on race gas or pump/methanol. I was making 380whp and trapping 117.9 mph with stock injectors with plenty of room to spare. I would have made 400whp with AEM.

well i need help what im asking is i have a walbro and 660 injectors and i just got a 35r kit and im going to trade my buddy for his 880 and i just need to know what fuel upgrades i need and were i can get them but the cheapest way, cant afford ams system not a lot of money left. SO SOMEONE PLEASE HELP. thanks
You need to do some basic research on fuel volume needs v. air mass that will be generated by your 35R based on your supporting mods.
In general, the stock fuel system with a uprated 342 Walbro (255HP model) is said by many tuners to support up to 450HP. If you're wanting to err on the side of safety, you'd buy a supply line of AN-6 or AN-8 and the necessary fittings to use it, an adjustable fuel pressure regulator, and a larger bore fuel rail. Your 880 injectors should be good to 450HP or so.
If you're not familiar with the theory of fuel injector or system sizing, you can get some general estimates of fuel needs here: http://www.rceng.com/technical.htm#WORKSHEET
