I was getting ready to hate on Holley fuel pumps...
... after just finishing replacing mine only after 2 years and 10K miles of service when it occurred to me the demise of this Holley 255 was more than likely my fault.
I've really never been familiar with the fuel system in the LT1 other than knowing what fuel line to plug in where. When I initially put this pump in I didn't pay any attention and just threw the pump bucket aside and hose clamped the pump onto the bracket and dropped it in the tank w/out a second thought and not learning a damned thing as to what I was doing.
So I buy a Racetronix in thinking I was going to do the same thing since the bucket is now long gone, however I find out the pickup screen will not fit on the inlet of the pump. Too small. I call my good friend, Chris (PWRSHFT) who's got me out of many jams before with the plethora of spare parts he has and he gave me a bucket. After looking at this further dawned on me something of great importance.
Keeping your fuel pump cool by submersing it in fuel is a good thing. When the fuel pump is clamped onto the bracket it is then air cooled once your fuel level decreases and, of course, runs hotter. I may be Captain Obvious to some, but to others who've posted what their interpretation of the bucket's usage is for I may enlighten you. The bucket's purpose is not to keep the pump supplied with fuel through "hard cornering". I believe the thank has baffles for that anyway. That is kind of impossible since the pickup screen for the pump is on the outside of the bucket. The soul purpose of that bucket is to keep the pump cool by routing the return line back inside the bucket, thus no matter the fuel level of the tank the pump is always submersed in gas.
Basically all I'm saying is if you are doing a pump install, by all means reuse your bucket. For pumps that do not have an off-set inlet the bucket is very easy to modify. No need to explain since I've seen the write ups on this site. A simple search for either "fuel pump install" or "trap door method" should point you in the right direction. Reusing the bucket could significantly prolong the life of your fuel pump.
