[dich]

Is there any difference between 1.8 t fpr and 7a one.Both are rated at 4 bar.I want to replace my 3b 3 bar fpr with 4 bar one.But I can t find a 7a one.Will the 1.8t fit on the fuel rail.

I am guessing that the 1.8t FPR is a clamp-in with an O-ring. (but I could be wrong) Your 3B needs a bolt in. Link to more info below this table:

7A, 20V NA, 4.0 Bar nominal, bolt in = PN 054133534
3B, 20VT, 3.0 Bar nominal, bolt in = PN 034133534M
AAN, 20VT, 4.0 Bar, clamp in to VIN P080000 = PN 078133534A (UrS4, Bosch 0280160516) (Clamp PN N10210602)
AAN, 20VT, 4.0 Bar, clip in after VIN P080001 = PN 078133534A (UrS4, Bosch 0280160516) (Clip PN 037133047A)
AAN, 20VT, 4.0 Bar, clip in = PN 078133534C (UrS6, Bosch 0280160517) (Clip PN 037133047A)
ABY, 20VT, 4.0 Bar, clip in = PN 078133534C (same as AAN) (Clip PN 037133047A)
RS2, 20VT, 3.8 Bar, clip in = PN 034133534P (Clip PN 037133047A)

i use 4.0BAR FPR from audi 2.8 v6 , I cut 2.8 fuel rail and weld it on one fuel line which go to fuel rail .
other side of FPR are plug n play into 3b pipe

yes they are..

most easy way to fix 4bar FPR on 3B engine is to use 2.8 v6 FPR .

there is lot of 4.0bar FPR in VAG group . and I think that 4.0bar FPR are all the same.

I have an adjustable 3B FPR, built with a conversion kit from a Finnish company some years ago. Works good and a nice kit. It's not for sale, but I can't remember the name of the company, maybe someone here knows it?

ive got 1 kicking about in my shed somewhere.. 7a fpr that is £10 plus postage...

The main benefit of the 7A FPR in the 3B is that it's a simple bolt-in replacement and it's cheap.

Yes! Thanks Thuppu!
