Most folks just remove the mechanical pump and go electric when that happens--I talked to Herb McCandless the other day and he even had to do it on his high $$ Imperial that he does the Power Tour with etc--Mopar sold a TON of soft crappy quality FP p rods at one time and that is the problem--Sorry to hear your trouble.

Thanks The rods only a little over a year old , Why does mopar sell that junk? really suck because its on a restored car so I really wanted the stock fuel pump without resorting to Elec.
Now I'm curious how much metel went in my engine.

If that pushrod is that trashed on cam end, I'd be wondering about the state of cam eccentric. bummer. I keep a few survivor pushrods around and trust them more than new ones. If that little 45 degree bevel is still on both ends, I'm using em.

I suffered the same problem with the worn pushrod but I was lucky once I finially got the plug out the rod came out with a magnet.
I understand the quality issues people are speaking of but some of the failures could be caused by the oil companies slowly but surely decreasing the zinc content in the oil & for the type of cam, lifters etc we use in these cool old engines we NEED that zinc.

Believe me I use zink oil assy lube on the rod everything. This rod probably has less then 500 miles on it this is nuts. The lobe is still moving the rod I cranked it with the pump off but the pumps just not pushing the fuel up. I pulled the plug but the rod hits a stop I assume the end looks like a nail now.

theres been problems with the pushrods years ago, soft metal mushrooming the pushrod. it happened to my 68 hemi rr.
the metal will be soft enough to wiggle out with visegrips on the pushrod.
id be looking for a different brand other than mopar performance as this is a reoccuring problem.

Funny you should say as this is also a 68 hemi Roadrunner ! must be a curse. I don't think I could get any vice grips in the opening with the jaws opened enough to grap the rod. What did you use?

Re: Freeing stuck fuel pump pushrod - 04/04/10 01:25 AM
Had the same thing happen to my new engine, I used needle nose vicegrips and did a lot of wiggling, eventually the rod came out. It took a lot of cussing. Be patient the metal is soft enough that the mushroom will curl up. Since then I have never bought another Mopar Performance part. Never will either. That was a $6,000.00 engine almost ruined by a $20 piece of garbage. Went to the salvage yard and got one out of an old car, no problems since.

Re: Freeing stuck fuel pump pushrod - 04/04/10 01:51 AM
A trick that has worked for me in the past is to take a box end wrench if you have enough room to get it into the open and slide it over the rod. As you push on the other end of the wrench, it will put pressure on the rod as a fulcrum action and will hopefully move for you. A flare nut wrench may also have to be used if it has fallen futher down towards the fuel pump arm, yet still be stuck up in the motor. Good luck!!!

Use "vintage" old ones--always! There are still some of the crappy batch out there on shelves--they had a rough finish on the tips--looked like they were done on a belt sander

Re: Freeing stuck fuel pump pushrod - 04/04/10 04:24 PM
Update!! I got it out this morning! I used needle nosed pliers and worked for 10 min. The metal was so soft it just flaked off. Beware I bought it new about a year ago from my friend at the dealership parts dept. Compairing it to the old one it has lost a good 3/16th. to 1/4" on the cam end. Now What would you guys recommend on removing a 1/4" of shaved metal from my motor?
I will change the oil and filter but , I guess I should drop the pad too? Now I need to find a good seasonded rod. Thanks for the help and if you have a MP pushrod lay around lose it! I will post a picture later.

Good to hear you got it out. 
The one I just ordered from Mancini is already starting to mushroom I pulled it out right away. What a piece of doodoo.

My new one (dont remem where I got it) has concentric rings on the end like tree trunk rings. I'm wondering if it's one of the bad ones

I think that IS a bad one. I bought a MP rod back in the 90's that had rings (sort of irregular rings as I recall), I ended up using the nice looking 30 year old original one instead.
A rough surface sliding against metal cant be good.

Re: Freeing stuck fuel pump pushrod - 04/04/10 08:39 PM
the way i found out i was having this problem is my motor would not stay running, i'd pour a little fuel down the carb and she would fire and then a few seconds later, my engine would stall, at 1st i thought it was the fuel pump but when i dropped the fuel pump, the pushrod wouldnt come out. after finally removing it, it lost a good 1/4" and it was totally mushroomed, i saved it for years over my kitchen sink, i just threw it out a few months ago.
i think i put another MP one in, i havent had a problem yet but i think i need to inspect it again.

I see Moroso, Comp, Crane, Howards etc etc make the fuel pump pushrods for small & big block Chevs but not BB Mopars 
As a turner I would have no problem making a pushrod but what to make it from & the hardening process is what's stopping me, any expert advice?

Jegs Chev push rod - Precision made from 4130 chrome moly tubing. Made in the USA.
Moroso - Lightweight design with hardened ends reduces reciprocating mass
ARP - They're made from premium grade aerospace chrome moly and centerless ground to precise diameter. A hollow core serves to reduce the reciprocating mass.
Barry Grant - Special lightweight high strength tubular push rod.
Comp Cams - Lightweight tubing with bronze tip for steel cams, Lightweight tubing For cast iron cams.
Manley - These pushrod is made for 4130 chrome mole steel tubing.
Carter - Chromemoly
Crane - Chromemoly
MP - Chromemoly
Crower - The Crower fuel pump pushrod is manufactured from lightweight steel tubing that is heat-treated for added strength. The bronze tip ensures proper surface mating with the fuel pump eccentric lobe on 8620 steel billet camshafts. This surface compatibility eliminates the wear problems associated with stock designs. For cast iron hydraulic and solid cams they offer a lightweight model with a steel tip at each end to protects against wear.
Well I guess I'm going to have a crack at making my own, from my experiance & the horror stories I hear here I can't do much worse than MP

Re: Freeing stuck fuel pump pushrod - 04/08/10 02:17 PM
What is the diameter? If it is a common size, maybe a guy could get a drop scrap of O1 or other good tool steel from a machine shop. A drop that length might be free. Or they might cut to length for a nominal fee. Just a thought...

Re: Freeing stuck fuel pump pushrod - 04/08/10 03:18 PM
After all the talk on this thread, I pulled out the new one I put in this February along with a new fuel pump and vapor separator.
Be aware - it was starting to hollow out on one end, this after less than 600 miles. The old rod had been in up to 103,000 miles (I've put on 3000 miles since I got it so at least that many) and there is absolutely no wear on the face of both ends. Got the rod at Mancini's just before Christmas so the current batch is highly suspect. Calling Mancini to alert them to the situation. Thanks for all your help. Saved an engine.

So I gave them the benefit of the doubt and checked all. Used Valvoline VR1 With a zinc additive as well. Plenty of lube. Stock fuel pump and the eccentric was perfect. So buyer beware! Pretty sad customer service.

I received no return message. (and i did not ask for anything but a reply) Well maybe someone will buy one of these rods, does something to their engine and then Mancini receives a lawsuit letter. That might get their attention.

I just got an email saying to return the rod for a refund or store credit. I guess it pays to complain. Shipping is $5 bucks for a $15 part.

Re: Freeing stuck fuel pump pushrod - 09/10/15 09:23 PM
Old thread, but I just had my original pushrod eaten up by my Carter high volume pump, so beware if you are running those pumps. I checked the specs on the pushrod when I installed the carter about 3000 miles ago and it was within specs. Now it is only 3" long and shot, and like I said that was an original pushrod, not a replacement. I have seen now that others have had problems with the carter high volume pumps being too stiff, and eating pushrods.
