Montecarlo71 Posted February 1, 2020 Share Posted February 1, 2020 So I have a 71 mc with a 454. THe fuel pump push rod is stuck. Want to put a electric fuel pump and eliminate the mechanical one. How do i accomplish this? Fuel pump suggestions and install? Or at least find a way to get the rod out . There are no bolts in front of the block holding it in place and I do not have a welder lol Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted February 1, 2020 Share Posted February 1, 2020 On the block, under the fuel pump rod is a threaded "plug". Remove that so when you free up the pushrod it will pass through the block. Try spraying the rod with some penatrating fluid. In your pics, the bolts spoken about are not there. Spray the penatrating oil in those holes. Most likely that's how the rod rusted in the block in the first place and why that part of the engine has excessive oil on it. Then using a heat source, torch, propane torch, heat up the rod and block a few cycles. Try and loosen up the rod with long nose vise grips locked onto the rod.

Montecarlo71 Posted February 1, 2020 Author Share Posted February 1, 2020 Ok thank you will due. So your saying the 2 holes on the front of the block is y it was rusted? How will I no the love on the cam is still good? Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted February 1, 2020 Share Posted February 1, 2020 I'm not saying that's why. Just possibly/most likely why. Glad to hear she runs. That most likely means that the rod moved enough to let the cam turn. So it may not be as bad as thought. 😁 Once freed up, if in ok shape you could hold the rod against the cam and crank the engine. The rod should go in and out of the block to check the fuel pump rod lobe on the cam. Quote Link to comment Share on other sites More sharing options...
Montecarlo71 Posted February 1, 2020 Author Share Posted February 1, 2020 Right on ya been working on it all day not freeing up. So just gonna plate it off and go on to an electric pump. Thank you for your insight, very inlighting. Quote Link to comment Share on other sites More sharing options...
imr Posted February 2, 2020 Share Posted February 2, 2020 when you turn the engine over does the rod go in an out. if not then either it is sort of in a neutral position and stuck or you have a worn cam lobe. with s tock fuel pump it would preload the rod to ride firmly against the fuel pump lobe.

Montecarlo71 Posted February 2, 2020 Author Share Posted February 2, 2020 Ya at this point it's in a neutral spot gonna get a electric fuel pump Quote Link to comment Share on other sites More sharing options...
714024SPEED Posted February 2, 2020 Share Posted February 2, 2020 I would try to get the rod loose. I would hate to think of it coming loose at high rpm and shooting around breaking the block. Quote Link to comment Share on other sites More sharing options...

DragCat Posted February 9, 2020 Share Posted February 9, 2020 I know this isn't what you want to hear, it may be bent and you will have to go through the motor. I found the below link , try google search but I didn't see anything that was easy peasy https://www.chevelles.com/forums/18-engine/376004-454-ho-fuel-pump-push-rod-stuck.html Quote Link to comment Share on other sites More sharing options...

Andy's Auto Posted February 14, 2020 Share Posted February 14, 2020 If the engine turns over fine, just leave it where it is. It will not hurt anything. 1 Quote Link to comment Share on other sites More sharing options...
