HPFP Banjo Bolt Leaking - Need Help!

**AudiKilla** · 10-02-2016 12:43 PM

Hey everyone,

After a month of driving without any issues, my pump started leaking from the banjo bolt. I have removed the banjo bolt and tried to torque it several times but it's still leaking. As soon as I turn on ignition, it starts leaking 1-2 drops every second.

Any tips guys? The banjo bolt doesn't look stripped either this is driving my nuts and I can't

Crush washers.

Hmm but how come it's leaking I don't get it

Just put a new bolt in there. Don't drive it until you do.

Does the banjo bolt come with any washers originally?

Looking at the parts catalog, I don't believe it does.

06F127213B for the Banjo Fitting
WHT000285C for the Banjo Bolt

There aren't supposed to be any crush washers there. Buy a new bolt. If that doesn't work, you'll need to look at the brass fitting in the pump and the banjo on the hardline.

Agreed. Yeah, don't hack anything to do with fuel.

You stripped the bolt/fitting. Take both out and check. The fitting is brass and cost about $50 bucks. The bolt is about $15. Sucks and is pricy. I converted to the hose type but I think I may have an extra set of both fittings. I will take a look.

The bolt is supposed to be replaced each time it comes out as per fsm

That's cause the banjo bolt is pipe threaded, I had issues with this for a long time until my friend came over and just cranked down on the bolt to get it tight.

Gonna buy a new banjo bolt in the morning and try again. If it still leaks going to try the crush washer.

Can't take the pump off to check the brass fitting until next week, one of the hpfp threads is messed up. Bought a cam adjuster housing with stud kit from a member here, it should arrive by next week.

Here is the actual issue ....
you didn't have the fitting quite square when you tried to tightened down the banjo bolt so deformed it a little . this is a very low torque bolt for several reasons.
1. I doesn't need to be high if the fittings line up perfectly
2. the banjo bolt is hollow with a hole drilled through it , if it snaps off you will be pulling the hole pump off again to fix.

Even if you get a new banjo bolt it may not resolve the issue if the fitting has been tweaked ( it doesn't take much. ) as the banjo bolt itself does very little sealing . it merely pulls the fitting against the pump face, and im sure that is where it is leaking, not the bolt face against the fitting
if this is the case copper or aluminum crush washers will probably resolve it as they will form to the imperfections and make a seal, but do not over torque that bolt.

Bottom line is take a few extra minutes and make sure that fitting is squre against the pump before tightening the bolt , don't just be thankfull you got the bolt through and eagerly start tightening. When the fitting is settled you will know it.

Good luck.

THIS. Except you can get that fitting out when a skinny wrench without taking the entire pump out. I stripped a couple of these and he is 100% correct. I wouldn't use crush washers because what is going to happen is you're going to be out somewhere and its going to start to leak and being as high pressure as it is you will be stranded or on fire.

Thanks guys, finally got it fixed. Had to remove the pump and torque the brass fitting, it was pretty loose. Also needed a new banjo bolt, the old one wasn't good.

Good to see that this was resolved.

It was just $10. So how often do you guys replace the banjo bolt?

I plan on checking the follower once a year at least.

Haven't done it yet lol. I've taken my moms on and off like 5 times still the same bolt, even got a new pump, still same bolt. Like was said above you just gotta make sure it's all lined up before tightening it but it sounds more like it was your brass fitting than the bolt
