The_aSSet Posted December 17, 2012 Report Share Posted December 17, 2012 You should be fine with the stock pump imo. Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted December 17, 2012 Report Share Posted December 17, 2012 Agreed. You can get a Inline Walbro 255. Honesty jegs or summit. Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted December 17, 2012 Report Share Posted December 17, 2012 on a return style system, I've had the stock pump to 504 at the wheels and it only started to drop off at 7000, so i would venture to say you'll be fine. last i heard SUPERSUB was running a stock flexfuel pump on his TVS 427 monster at over 700 to the wheels. Guys don't give the stock pumps enough credit. Quote Link to comment Share on other sites More sharing options...
ryanneugebauer95 Posted December 17, 2012 Author Report Share Posted December 17, 2012 so yall think i will be good with the stock pump? im not pulling it past 6500 and the injectors are only 36# is mine a return style fuel system? its a 07 classic. my friend zach (zachm89) told me that i needed a bigger one, but maybe thats cause he wanted me to buy his lol. if the stock will work fine then that is perfect cause i wasnt looking forward to dropping the tank or pulling the bed. thanks guys Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted December 17, 2012 Report Share Posted December 17, 2012 (edited) You dont have a return style system. 2003 had a return style and then from there they went with return less setups. If you are concerned with fuel, and plan to add more power then a inline Pump wouldnt be a bad idea. That would cover you from having to go either return style or adding a intake pump. I always add a inline pump when I mod as a precaution so I know I have the fuel as I always continue with the mods being added. Like said the factory pump will be ok but if you plan do more add ons I would do a Walbro 255 inline pump. FYI.... I had a stock fuel pump in my 91 Camaro backed by a Walbro 255 inline pump. The car had a 406 SBC Stroker that made a little over 600 HP to the wheels. I ran it this way from 2005 until I sold the car last year and never ran out of fuel.

ryanneugebauer95 Posted December 17, 2012 Author Report Share Posted December 17, 2012 Okay so what would y'all say I need? 36# injectors not very big but I just need to know what y'all think I would need. I need a part number if I need anything besides the stock pump too Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted December 17, 2012 Report Share Posted December 17, 2012 (edited) You will be fine on the stock pump. I am running a TSP-228R with 42# injectors on the factory pump. The stock pump is sufficient. Just do the injectors and call it a day.... Edited December 17, 2012 by Fireman31 (see edit history) Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted December 17, 2012 Report Share Posted December 17, 2012 (edited) absolutely fine, like i said, this fuel pump thing is an Internet band wagon that has been repeated so many times its becoming truth...much like the stock exhaust pipes and rod bolts aren't good enough. although if you had to buy one, Zach would be a guy to buy it from. Tell him to stop around here more what 36# injectors? Flex fuel? Edited December 17, 2012 by shadowsniper3006 (see edit history) Quote Link to comment Share on other sites More sharing options...
ryanneugebauer95 Posted December 18, 2012 Author Report Share Posted December 18, 2012 Yeah i got some flex fuel injectors. they came off a nnbs intake that had the same part number as a tbss. Zach is a busy guy. He just got me a 850$ converter for 650$ so i guess you can say hes a good guy to know haha. thanks for the help guys much appreciated.

ryanneugebauer95 Posted December 18, 2012 Author Report Share Posted December 18, 2012 Oh, one more question. My tuner is always really busy (or hes never at his shop in other words) and last time i had him do a retune it took over two months to get him to do it. i can get a hold of him easier now and im sure it wont take long for him to get to it this time, but what parts can i run without a tune? i know it wont run too good but its my DD and i need it everyday. what parts are safe for me to run with the tune thats on it now? its an hptuners tune btw.

shadowsniper3006 Posted December 18, 2012 Report Share Posted December 18, 2012 (edited) You need adapters for the flex fuel injectors don't you? aren't they like ev6 connectors or something? i would not run ANY cam or injector change without a retune. Buy an extra pcm and have him tune that one for the change so you can drive the truck with out the new tune and then swap the pcm in right away with the new tune. Back in the day when i had mail order tunes, not email, i had 3 pcm's for my truck so i could run 2 tire sizes and always have a spare to send to my tuner for updates.

ryanneugebauer95 Posted December 18, 2012 Author Report Share Posted December 18, 2012 im not sure about the injectors i havent looked at them yet next to the stockers. ill check tomorrow. im thinking he can throw something together to get it to where it will run okay till he has the time to really tune it. this weekend is the big weekend. thursday the stall is going in and saturday and sunday mayne is the cam and all Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted December 18, 2012 Report Share Posted December 18, 2012 You can drive the truck with a convertor and a cam for a short while without a issue. I drove my car right after a procharger, exhaust, cam and 3200 convertor for a month without any issue. Minus a check engine light which is normal... Just drive it normal and not like a jerk and you will be fine. Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted December 18, 2012 Report Share Posted December 18, 2012 (edited) Check those injector connectors out. If you need pigtails it can hold you up on your daily driver. And yeah....don't drive a truck with a cam and injector change with out a tune for at least the correct injector files. When it tries to correct it will have no idea what it's doing. Will the motor survive on a mild set up, yeah, but it's just not right. Hopefully he can get you that update Sent from my SAMSUNG-SGH-I747 using Tapatalk 2 Edited December 18, 2012 by shadowsniper3006 (see edit history) Quote Link to comment Share on other sites More sharing options...
