It is running like **** i have a holley blue pump on it right noe fuel pressure fluctuates pump makes weird noises this is my 3rd pump since 3 months...... Use to run fine please help me

 

have you checked the voltage to the pump yet? If you are going through pumps that would be the first thing I look at. Seconf I would look for foreign matter in the tank ie rust or corrosion. That would clog it causing stress and eventual failure. Next I would check the lines to make sure they can handle the flow given to them this would be like running a 1" charge pipe on a 60+ trim turbine.

 

im changing out the fuel filter and running a 3/8 fuel line instead of the stock lines

 

what u got the pressure set at? the holley needs like 6lbs.

 

yeap! tank dirty, check fuel pump wires, clog fuel filter or line...also clean carb fuel bowls. Hard to really tell with a "running like ****" problem.

 

i cleaned out pretty much everything ran a 3/8 fuel lines runs good but needs tuning 2X a day and fuel pressure fluctuates form 14psi to 5psi when it runs a little while ??? im just going to sell it to much damn work

 

yea rxtasty3 we basically have all the same stuff in our cars how fast is your car? and do you have problems killing on turns i cranked my floats down but will still die out any solutions?

 

how much do you think i can sell this for?

 

wow 2 more posts to sell this damn thing

holly fuel reg wo wthat deal gap looks fun besides my car bogging on corners ive been their on my bike tho really nice

 

if cranking floats down u mean lowered the float level, u got it too low and it's running the carb out of gas. and yes i have the same problem with it bogging on hard cornering. it's just the characteristics of the holley due to the way they're positioned on the intake(sideways) than the way they're normally run on a V8.

 

ive had it run very nicely before on the turns but its my fuel pressure bounces up and down and messes up the float level
