my 79 2wd runs like shit, anytime i try to get on it, or rev it past 3k it dies out. i can turn off the key and wait for about 10 seconds, turn it back on and it runs like it never happened. im wondering if theres crud on the filter inside, plugging the line when it needs fuel the most, therefore killing the motor. Any suggestions would be nice.

You do know about the filter just in front of the left rear wheel, on the frame rail.?.?

It could be a fuel pump that can't keep up, but I would try the filter and clogged/ kinked line first.

OK, I'm over it. Where's the beer?

Don't forget the one inside the pump itself. End comes off, out pops a pleated paper filter. Auto parts store will say there is none listed there for a Luv. Get one for a Datsun 240Z that is listed, and you're off and running.

thanks guys, i changed fuel filters, the one on the frame rail, just kinda thought the fuel pump was toast. ill look into the in pump filter and see if its clogged.

I've seen the insides on four LUV tanks now and have yet to see one with a filter screen of any kind on the pickup tube in the tank. I cleaned out the tank on my 79, cleaned and swapped one from a 76, and had a couple of 77 tanks swapped around. The pickup tube points straight at the bottom of the tank into an indentation, no room really for a screen. The only clog you could have in-tank would be crud built up in that dent below the tube high enough to limit flow.

FYI, I had really good luck cleaning the grunge out of tanks (once they are pulled out of the truck) by just pulling the fuel gauge sender and blasting the insides with a pressure washer through that hole. If you go to the self car wash at night they usually don't complain much and you can get hot soapy water. Clean it inside and out, swab the inside a little with a paper towel and a stick, then sit it in front of a good heater/fireplace, and its good as new. Well, none of mine blew up, your mileage may vary.

One more thing, I've had bad points sort of mimic the same sort of symptoms. Runs ok up to a certain RPM then falls on its face. With a fuel supply you can usually get it to go past that certain RPM range for few seconds if you've been sitting at idle. Points it falls down every time at the pretty the same RPM except maybe when not under any load.
