Wow I had no clue this was possible.

i thought i got average miles per tank (260) but if you think that i am that bad then i must be really bad lol
i have the normal filter the one that come stock of course i check it all the time and its perfectly clean, one time i got only 153 miles per tank thats like ifi was driving a ferrari!! but then i changed fuel filter and it went up to 260 and its been around there all the time!
what can i do! where can i find a fuel pressure regulator? how much are they? i know nothing about car mechanics i am 19 and have no idea about anything of this stuff, back in mexico i never had to change oil or fix anything as soon as there was something wrong my dad sent the cars to get fixed so your help is appreciated

Sorry to alarm you Pepino - I thought you were getting 150 miles per tank regularly. 260 miles per tank is about right if you drive hard on oxygenated (10% ethanol) gas like I do.

If you don't know your way around an engine, then changing the FPR is no place to start learning. Any mechanic should be able to take care of it for you - an hour's labor to install it plus the part, which you could get at an Isuzu dealer, online, or from an AutoZone or other parts store. It may help, it may not.

Do a search on here about the fuel pressure regulator.

I disagree - It is a very SIMPLE instal. The hardest part of the install is getting an allen wrench to turn the rear bolt (honestly).

It is about $70 bucks and if you can get the allen bolt off it takes no more than 20 minutes. I did this install and I am no mechanic.

I jumped from about 10 mpg to about 14-15 with just that. I am now running 17.5 average - and dont forget I am lifted with bigger tires.

Here is my thread on it:

All I had to do was lose 5 quarts of supurfulious oil



Best,

Man, I've done that before. I know for sure that one 340 miles tank was not an illusion. But, now with the lift and new tires, I will be happy with 250 a tank.
