: 1983 Caprice 305hp fuel pump
Raven 04-29-2005, 07:10 PM Iam removing the fuel pump, i read my Chilton book and it said to remove the upper mouing boss bolt, then insert a bolt to hold the push rod, where is this bolt? do you have a photo of hte location?
( small block chevy)
thanks!! Raven
Raven 04-29-2005, 07:14 PM what size is the wrench to remove the fuel filter line from the carb,
my 5/8in fit to wide, is it metric? or a odd SAE?
greywolf 04-29-2005, 08:53 PM Yes, Chevy changed to metric size hardware.
I changed the fuel pump on my [1984] 305 and there was no upper bolt and yes the push rod slid down a bit which prevented the new pump from going in [it doesn't fall into an unknown pit]. No big deal, once I got the slippery devil back where it belonged and somehow managed to hold it in place the pump installation was a snap.
As long as you are working with the fuel line consider changing the fuel filter in the Q-Jet.
Fun isn't it! :D

Oh yeah, make sure if you are installing a aftermarket performance pump that you put a pressure gauge somewhere so you know if it puts out more than 6. My holly out out something like 10-12 and would flood the carb!

Orfunauto 05-06-2005, 05:36 PM What they are saying, is that there is a bolt on the front of the engine, just around the corner from the fuel pump. There are actually two holes on the front of the engine. The top hole lines up with the fuel pump rod. On the later model engines, the top hole has a short stubby bollt screwed into it. Remove that bolt and install a longer bolt. FINGER TIGHT ONLY or you will scar the pump rod. This will hold the pump rod in place when you remove the pump. Much easier than trying to push the rod back up into place when it falls down.
For the younger folks, those two holes were originally the motor mount bolt holes for the early models. Don't forget to replace the bolt with the shorter one after you're through installing the pump.
dave1987SS 05-19-2005, 06:28 PM When I replaced my fuel pump I did not know about the short bolt, I found an easy way to do it was to put a blob of grease on the pushrod and jam it up into the hole until it reached the cam, the grease held it in position until I got the fuel pump bolted in, and the grease will not damage the inside of the engine, it mixes with the oil and dissolves out in your next oil change.

84 G camino 06-20-2005, 08:58 PM if the pushrod doesnt seem to want to go back into the hole at all, BUMP SLIGHTLY the ignition or better yet spin the crank bolt to rotate the engine till the cam lobe is down, then the rod will give a bit more.

just around the corner from the mounting plate for the fuel pump is a small/short 3/8 bolt...remove that bolt and get a bolt with longer threads ...this will hold the push rod once you put it way up into the slot it ride in and keep it there...don't forget to remove the bolt with the longer threads and install the short bolt once your done....the push rod won't like the longer bolt at all!!!

Raven 11-13-2005, 10:26 AM thanks for the info, on the fuel line, i went to sears and bought 5/8 flare nut wrench and it worked.
