Hardened Fuel Pump Pushrod

[unclepunchy]

I am running a Solid Roller Cam (Billet) and just purchased the Melonized Dizzy gear and hardened pushrod from Hughes. Am I good to use the hardened pushrod or do I still need the bronze tip?

I tried several times to ask the Hughes techies but they are impossible to get a hold of and are taking up to 4 weeks to answer emails.

Honestly.....that worries me. Hardened could put it past the hardness of the cam lobe and cause it to fail?

Billet cam, yes, you need the bronze tipped fuel pump pushrod.

What confused me is that the Melonized (Hardened) dizzy gear is okay to use but not the hardened pushrod? I guess they need to make a melonized fuel pump pushrod. :}

I am just trying to make things as low maintenance as possible. I dont really want to worry about checking the bronze tip for wear, etc. I guess I could just buy a blockoff and go electric pump?

Run the bronze tip, and if it goes to ****- move to the electric pump?

Not a bad call. How often do you folks think I should check it? Just normal street driving, no strip.

If you run out of fuel pressure, time to investigate.

Melanized is only a coating, not hardened. The issue is that they can not be similar metals or else they will abrade each other. The bittet cam is a hard steel so the other part needs to be softer (bronze) or coated (melanized).

Lube the wear area before fire up with cam/lifter grease.
Measure it before you put it in - and pull it out after 6 months and check it.
There will be some initial loss of length as it wears in.
If the tip is an inferior metal it will have worn quite a bit.
The tip should be a wear bronze not brass.

Thanks, roger that.

Looks like the Pushrod Hughes sells can be used with Billet Rollers. I just got an email reply from Dave @ Hughes.

This will destroy your cam and pushrod. It does not have the bronze tips
