Here is the latest and greatest from Walbro. This is basically the F90000267 pump with a 140psi pressure relief for those that need high pressure, or just want the peace of mind knowing it's not going to relieve pressure until that level.

These are the quietest, most powerful, highest flowing, low amperage drawing pumps on the market at the price. Two of them will knock off an expensive external in terms of flow, while being quieter and drawing fewer amps.

These pumps are good for over 750HP on E85 at 13.5V, two of them flow enough for 1000HP with the proper setup.

Pump includes:

Genuine Walbro F90000274 E85 fuel pump
Strainer

We have optional fittings that we'll install for you to convert the pump outlet to straight 5/16 MQD, or 90* 5/16 MQD (single or double output).

Modern fuel systems no longer use rubber components because of their incompatibility with modern enhanced pump gas which contains ethanol and other solvents such as toluene, xylene and MTBE. Unlike flex tubes, rubber hose will break down very quickly when exposed to these types of fluids. This will allow vapors to leach into the atmosphere and cause the hose to swell and burst. Rubber particles may also contaminate a modern fuel system causing jet pumps, siphon pumps, check valves, regulators, diverters and injectors to fail. When replacing a fuel pump in a new fuel system, it is imperative that a new fuel tube be used.
