Been a while, but here goes. I have a lot rat Samurai that has run great til now. As the floor is all rotted out, it is easy to get to the fuel tank and check things out. Pump is dead. Now for the fun part. If I pour a little gas into the air cleaner tubing, the thing starts right up and runs well until the few tablespoons of gas are used up. So the question is - will a boat tank hookup with a pressure ball be enough to run the vehicle at all the 10 or maybe 15 mph out in the woods? I keep in 4 low and occasionally get to 2nd gear. With chains on all 4 your teeth tend to rattle above that level of use.

So while the fuel injection system reportedly needs a high pressure infeed, I am not sure if that is true for low rpm and speed use. Has anyone done this?

Suggestions please.

The top feature of fuel injection is that it provides a constant fuel flow at all rpm levels.

What you describe as an alternative is not a workable solution.

Ouch! Anyway, thanks John. I do have a Chevy Vega fuel pump (don't ask) in the dust pile, new in box. Not sure what pressure that provides, but they were built with a recycled flow carb system. Put that in a boat tank and plumb it properly? Trying not to spend money on a lot rat. .... Well, trying not to spend money....

When it comes to fuel systems, I am a big proponent for pending the money and doing it according to original design.

Gasoline is highly volital. I consider my life worth the extra expense of not cutting corners on fuel systems.

That said, compare the flow rates required of the two vehicle engines. Then, ensure you have a return line. Both in and out lines need to be of sufficient diameter.

And, ensure that any rubber hose is specific for fuel injection systems. The more you can use steel lines, the better.

Thanks again. Hopefully others will chime in. I guess I could put in a replacement pump but I am concerned about the integrity of the tank as well..Lines are good as is, but the typical tank rust issue is a concern. Vehicle has cost me all of $100 or so and is a candidate for recycling. Would like to keep it as it is a real workhorse.

Hey John. A friend suggested using an inline rather than aan in tank pump. Sure would make access and maintenance easier as well as reduce rust issues. Do you know what the vehicle spec psi is? Thanks , Bill
