|
|
The fuel pump push rod on my '73 Thing was installed upside down by the PO. No biggie, but it was bent as a result.
I'm not with my car now, but can anyone tell me the what the proper length should be? I see two available on CP1.com

Depends on your fuel pump:
If the plunger lever on the bottom side of the pump base is flush, you need the shorter one (100mm/4"). If the plunger lever is recessed into the base of the fuel pump, you need the longer one (111mm/4.25").

Two types of fuel pumps are used on VW air cooled engines. A taller pump was used with Generator equipped engines (earlier VW's), and therefore it used a slightly longer pump rod, and the Alternator equipped VW engines used a smaller "angled" pump that uses a shorter rod.
So, do you have a generator or an alternator? A previous owner (or yourself) may have switched the Generator to an alternator (popular swap on earlier VW's), and therefore swapped the fuel pump out too. |

My engine is block stock '73 Thing. 54,000 original miles. So, Generator. Happily, the electrical system is robust (even the cigarette lighter works) so I won't change it.
I was going to order from www.cp1.com, but when I went to check out, I got a DNS "Page Not Found" message.
Guess I'll try elsewhere. |
