Fuel pump issue...
Hello friends! It's been awhile since I last posted. I have a question I'm hoping someone might be able to help me with...
Been having acceleration issues... Took car in today... Mechanic did a fuel pressure test and said I was down about 15%.... Car needs new fuel pump assembly... He quoted me a price of $525.00... Probably going to take it to another cheaper shop (at the time, they lacked a fuel pres. gauge). Thing is, went online to purchase part and noticed prices range anywhere from approx. 65 bucks all the way up to 300+ for AC Delco... My question is, why such a dramatic price jump? I understand name brand dealer parts cost the most but it looks like their is a wide range in price with all the other brands. Is there something I'm missing? Looks like they all contain needed parts with a direct fit (sender, wiring ect.). Anyone have any insight into this?
Thank you!!!

To add with Chibi's comment it can also vary (in some cars, not sure if it does in ours) if you are buying a pump by itself OR a complete drop-in assembly (pump with sending unit and such).

just get the $100 option from ZZP or find a Walbro 255 for GM, they are direct drop ins and you can seriously do this in less than 30min. it takes about 5 mins to pull the assembly out of the tank, 10 mins to switch pumps, and 5 mins to reinstall.

Okay, I stand corrected. You did say a Walbro 255 for GM. I never found one when I did my pump change but there is one on eBay right now for $62.00. LOL if that's even a Walbro. I would only buy a Walbro from a reputable source; not anything on eBay because it's probably rebadged.

for the venturi issue, the mod really isnt all the difficult and in the 6th gens, you dont have to drop the tank to get to the pump assembly. to do the required venturi mod, its very minor in comparison
but yes, there could be a requirement for the venturi mod if the proper pump isnt purchased.

depending on the year of your car...on the 6th gen, there is a door underneath the carpet in the trunk that is very easily accessible...of course, on the 5th gen, the tank has to be pulled...as far as fuel pumps...being a service manager, i don't use the cheap pumps...price reflects quality, bigtime...if you want to replace the pump in six months, get a cheap pump...when i sell a fuel pump to my customer, i ONLY get a factory pump...get the ac delco or delphi pump...you will spend more $$ on it, but you will get what you paid for

The reason I don't like the venturi design is because it lowers the PSI and flow rate. If you have a Walbro 255 lph pump and you "t" off the line to run the venturi, you are lowering well below 255 lph and dropping the PSI. I've seen a different aftermarket kit designed for muscle cars that want to run EFI and the kit involves an in-tank pump but foam is wrapped around the pump to keep it wet at all times.
Has anyone tried this before? I would like to do away with my can altogether.
