Sudden Fuel Rush During Cold Start.
94 F350 7.3idi Engine K
Hello all, Its been a while, Hope all is well.
94 F-350idi occasionally gets a sudden rush of fuel when cold starting it along with some occassional clacking noises during warm up mode. I recently change my low pressure fuel pump that went bad after 2 years probably from not driving it enough since I had a company truck. it sounds healthy once in normal mode. Can anyone suggest what could cause this?
Also 94 IDI Engine K- Hydraulic Lifters or do there need to be a manuel valve adjustment?
Thanks.

You have an airleak in your fuel system thats starving the engine of fuel. The idle governor tries to increase the RPM as the engine is purging an airbubble, and then as air bubble passes, the fresh fuel causes the engine to surge. After a minute or two, the air is purged out of the system and it'll run smooth again. Look for wet spots on your fuel components like your fuel filter and the injector return caps.
