Hopefully this didnt happen to you but its entirely possible. If it did, this will be an expensive lesson. Do you have a scanner? It would be advisable to scan the truck for codes. |
Anything that is similar to the stock lift pump is NOT a good replacement. Trust me I went through a few factory lift pumps before I installed my FASS at just 48,000 miles! You better off getting a FASS or Airdog and saving yourself a lot of headaches down the road with your injector pump

Ok...Is the Airdog Raptor FRRP a decent pump? My biggest concern is dependabilty and my budget is stinking tight right now (I know...not nearly as tight as it will be if I need a new 44). This truck has served me well all these years and I have never had a fuel system problem or a problem with the engine in any way. Corroded connections has been the only problem I have had under-the-hood. Must be my time.

i have a Raptor FRRP, great pump, and real easy to put on. i like mine a lot. no problems at all, perfect for a stock or basically stock pick up. Plus they come with a four year warranty.:tu:

building any oil pressure when cranking

Last night I checked the lift pump one more time. I made sure it was as quiet as possible. Tapped the starter, stuck my head under the hood and I could hear a faint "buzzing" coming from the lift pump. The "buzz" continued for 30 seconds so I knew the pump was getting power and was attempting to run for the 28 seconds. I pulled the inlet banjo bolt from the fuel filter and tapped the starter again, listened to the "buzz", but no fuel ever came out of the line. So am I now safe to assume that the lift pump is trash (evidently more so than it was when new).
