ok just lately i've been having choking problems while accelerating. and when my car is idle it sounds like "putt putt" ever few seconds or so. also my inline pump sounds like the fuel isn't flowing constantly and it sounds choppy. i have a full tank of fuel and right now my fuel setup consist of a stock intank pump, FMU, inline pump, and stock injectors. oh and my fuel gauge sending unit is broken so right now it's on E even when i have a full tank. please help... my car feels like it's limping.. thanks!

 

next mod on your list should be a fuel pressure gauge on the fuel filter to determine what the pressure is and where it should be at

 

shouldn't it be at stock fuel pressure with my setup? this problem just happened recently... it didn't do this a few month ago.

 

could be at stock, but it just might be slightly below stock PSI.

when's the last time you replaced your fuel filter

 

i replaced it around 7 thousand miles ago.

 

wow, hmm, strange.

I would invest in a fuel pressure gauge and see where it sits if your motor is bogging on you.

is there any given RPM it bogs at? or under certain temperature conditions?

also, have you messed with ignition/cam timing at all?

 

it only bogs when i press the throttle about less than half way. feels like i'm running out of gas or something which isn't the case. i have completely stock timing.

 

?

 

i have the exact same problem. i have a walbro 255lph fuel pum and it sounds lke that too . still cant figure it out either

 

ok my car's gas gauge just decided to kind of work today and my car is running like normal. but what the heck is going on with my car? fuel gauge sending unit? but how could that affect the way the gas flows??? right now my gas gauge is reading 1/4 down from full and i've only driven 25 miles on the tank of gas... please help...

 

I'd get that fuel sending unit fixed, and get a fuel pressure gauge on your fuel filter to determine if your car is getting the right amount of fuel to the engine.
