 Posted: Sat Jun 16, 2012 11:18 am Post subject: I cant catch a break - fuel pump leak |
 |
|
So finally got the injectors in. (*thanks BradeyBunch!, payment on the way)
I just filled the tank up with has and I noticed that there was a slow leak. Did not exist before. Seems to be coming from rubber portion of fuel pump. Would this be maybe a bad fuel pump or just a loose connection.
My fuel pressure is fine, it just leaks about a drop every 30 seconds
thanks in advance |

Yes....its fairly common with age on these pumps. Many of them are just getting too old. Its most probably coming from the little nipple where the relief valve resides.
Do yourself a favor....dont get hung up with the type 3 crowd in trying to rebuild these pumps. Unless yours is pristine in the inside...you are just asking for a berakdwon somewhere. get a pump from a Ford escort. Works just as well.....1/3 of the price new....and easy to get. Ray |

Actually, it's an Airtex 2000 from a Ford Ranger.
Oh, wait- I'm a Type 3 guy. I'd better concentrate on getting hung up on an OE pump.  
Actually, they're available new again, and the price is somewhat high but not astronomical:

This is for D-Jet only- L-Jets like mine use the Bay Bus/ Vanagon pump.

yeah the OG repo one is a bit pricey for me right now. Could you maybe link me the correct pump to buy. i saw quite a few on amazon and i figure i should order sooner then later as the type 4 is my only car
Thanks again for all the help

Here's an El Cheapovitch off brand of the same thing on the Bay of E:

These are a straight- through pump, so just plug the little return line from the OE pump to the tank. Make a couple pigtails that you can run from the Ranger pump to your OEM plug, with male spade connectors to plug into the OEM plug end. This way, you can go back to the original style pump whenever you want.
Don't install it backwards.

Thanks for the correction! ....i was sitting in an airport using only one brain cell.....and you know what I mean Tram (I think).
I actually applaud rebuilding when it makes sense. Its nice to keep as much original as possible. So much is disappearing of the history of these cars.
I think Jim Adney revuilds them. I have rebuilt a couple and been inside many of them. The problem is that even the seals that Jim has come up with (from what I read) are not exact. The tolerances of pump head fit with seal have to be really exact. Its a fitted molded, square edge seal.
All of that aside, the condition of the rollers in the cells, the bearing areas on the shaft etc....make a difference on how well itwill even pump if rebuilt with correct seals. Having the original style pump is really a collectors item issue.
With things that are largely out of sight like fuel pumps....when it comes to 411/412....I try to err on reliability side. You just cannot afford to breakdown in some areas with the amount of investment and rarity of parts.
It sucks to walk away from your car in a bad area and come back and find it trash, stolen or towed. Been there and done that long ago. there are too many times when AAA is not fast enough.
If I were still a type 3 guy..... meaning owning and driving one...I would feel the same way with reference to putting an either ancient or unobtanium pump in one of those if ite were my daily or frequent driver.
I did not know that the original pump had gone back into production. I had not been keeping up with that part. I plumbed in a Bosch 044 a long time ago with a feeder pump.
Even those are expensive enough and getting hard to find enough to warrant replacing.
Nice information! Thank you Tram! |

There is really no downside as long as its plumbed correctly. Its basically the same as an L-jet pump and puts out roughly the same specs as a D or L pump or better.
The way to run this is to run the return line to a "Y" fitting (not a T)....with the downward leg of the Y to the tank...the open top of the Y facing the engine....right hand fork to the pump...left hand to the return line coming from the engine.
leave your inline damper in line where it is. You "might" need to move the fuel filter to between pump and engine but maybe not. The type 4 fuel tank flows pretty well. Ray |

| I installed a new style pump, and it works, but it sounds terrible. At first I thought there was something wrong with the pump, but I tried another new pump and it sounded the same, sort of a loud gurggling. Has anyone else experienced this? Can anyone offer any insight as to what the issue might be? The car runs fine, the pump just sounds really bad. |

This is not out of the ordinary...they can be louder....but....depending on how it is plumbed it may or may not be cavitating.
The original D-jet pump had fairly good suction...which is out of the ordinary for most of the straight inline pumps.
You need to be sure that the return line is plumbed into the segment between the tank and pump....with a "Y"...not a "T". The T causes cavitation and turbulence when it intersects fuel flowing past its port at 90*.
so the return line plumbing from the tank rearward goes...... Tank>>bottom leg of Y>>>right leg of Y to intersect a Y that feeds pump>>>>left leg of Y to return line to regulator.
Depending on the pump you may also benefit from having a simple low pressure fuel filter in between the pump and the tank on its feed line...as an accumulator. What pump did you use? Ray |

Is this the Ranger style pump?

This is where the cube shaped filter already is, correct? A different filter than stock, or would the stock filter do? Thanks--Brad |

| Yes. The fuel filter is between tank and pump. The difference I can see is that on most L-jet systems the tank is a bit higher than the pump giving a little better flow. The, cube filter should be enough. ....but this is also why keeping the return line plumbed inline with the "Y" connector between filter and pump is a wise and simple idea. It gives the pump an added volume of already filtered fuel to draw from. Ray |
