ok im building my 383LT4 and i expect to make (hopefully) well over 400rw. I was wondering if instead of buying the racetronix intake kit and go through all the hassle if i could just get a walbro inline pump instead. If its not worth it i dont want to take the risk...

 

It would be much more worth it to do a good 255 LPH in-tank pump kit. It may be a little bit of a hassle (not much) but it would be worth it....JMO. From what I hear, In-line pumps do not flow as much as a good in-tank.

 

Well, the main concern would be your stock in-tank pump. An in-line would help, but if your in-tank pump took a dive, it would take your new in-line with it. Just get an in tank, and you won't have to worry about it anymore.

 

My in-tank pump took a crap on me years ago...it would say 43 psi while idling, but going down the road WOT it would drop to 10 psi. Turned on my in-line and it held at 43 psi just like the in-tank did, but WOT it would hold steady @ 37 psi if I recall...been a few years.

IMO, but the fuel pump in the tank and be done with it.

 

well my intank pump is fine..i just need something to feed the 42lbs injectors and new found power..but if you guys say its not worth it..im not gonna take the chance on an 8,000 motor.

 

If you have spent that much to get everything else right, I would spend a little extra time to do an in-tank and do it right.
