Exhaust and fuelling?
Hello all,
I recently bought a 1999 S40 T4 for pennies from a family member. And I am currently going through bringing it back to its former glory. I have a couple of questions regarding fitments of some parts; 1) The exhaust has snapped between the first silencer and the joint to the cat converter section. I was wondering if the middle section of the exhaust is the same as other S40s? I.e the 1.8 or 2.0 litre models, as there are a few at our local scrap yard with great condition exhausts, or would they be too smaller diameter? Failing that the only one I can find for reasonable money is made by Clarius, which are terrible for rot! 2) I was warned that the fuel pump had been replaced by one from a smaller engined S40, I am not sure which engine but I assume it won't be able to keep up with the demand of the T4 under high boost? The car seems to cut for a second or so when held at WOT in 3rd/4th as the revs build up, could this be pump related? Seems worse when under 1/4 of a tank and happens when low on fuel and cornering! Can anyone recommend a decent aftermarket replacement for the standard T4 pump, as they seem very expensive new at around £270! Any input would be great! Thanks, Mike. |

Thank you for that info ww1dm1! Could you recommend a decent aftermarket fuel pump which may fit? As the official ones seem a little expensive at £270! I am not planning on driving the car again until I have these issues sorted anyway due to fears of it running lean. I am going to just bite the bullet and order the klarius exhaust I think!
Regards, Mike. |

Best option is to retrofit a Walbro 342 into the original sender unit. Make sure you get a genuine one, lots of copies and fakes floating around eBay!
Guide here: http://www.30forty50.com/forum/topic..._fromsearch__1 The Walbro 342 is recommended over the 340 in the guide as the pickup is more similar to the OEM pump so will give zero issues with pickup uphill or round corners.

Hello everyone, today I changed the oil. Oil filter. Air filter and fuel filter, starting from warm or cold is smoother and the throttle seemed more responsive. Took it out for a drive and I'm not sure what I have managed to do but it's not happy
It was bogging and holding back loads when accelerating in 3rd gear and then it bogged out completely until I let off the throttle and back on! The next time it did this I kept my foot to the floor and put the clutch in to see what happened. The revs dropped slowly to idle and then shot back up again! Any idea what this could be? Have I upset something whilst doing the other work as not sure if anything I have done would have had a negative effect? Thanks. Mike. |

What engine have you got? Edit - '99 T4 - sorry just noticed there is a first page in this thread
Checking the fuel filter would be my first port of call - perhaps the seals aren't in properly?

Hello v40alex,
I had a pole around checking all the work I had done. And checking anything I might have upset in doing so. And couldn't find anything obvious. Drove it today and it's perfectly fine! Not sure if there was an air Lock in the fuel filter or something? Thanks, Mike. |

Air in the filter was what I was thinking, sounds like it just needed a burp
